Within the framework of this article, we will try to figure out which wheels should be put on the VAZ 2107. The marking will be disassembled, which indicates what sizes this or that disc, this or that tire has. Based on the information given here, everyone will be able to independently choose a set of wheels for their "seven".
Factory parameters of the rims of the "seven"
The AvtoVAZ automobile concern installs steel rims on VAZ 2107 cars, which are designed for mounting tubeless tires. Factory wheels are marked 5Jxl3H2 ET 29. Let's try to figure out what this means.The number "5" is the width of the rim of the disk. Unit of measurement - inch
Article "J" is symbol special rim profile
The number "13" is the landing diameter of the wheel rim under the tire. The unit of measure is inch.
The combination "H2" - this means that there are two annular protrusions on the rim of the rim, which are designed to install a tubeless tire
The article "ET" is a symbol for the size of the offset of the rim of the rim
The number "29" - the value of the size of the offset of the rim of the rim. Unit of measurement - millimeters
Factory parameters of tires "seven"
Leaving the factory, VAZ 2107 cars are equipped with tubeless tires, which are marked 175 / 70R13 82T. Let's now understand what this means.The number "175" is the width of the tire profile. Unit of measurement - millimeters
The number "70" is the ratio of the height of the tire profile to the width of the tire profile. Unit of measure - percentage
Article "R" is the accepted designation of the radial tire
The number "13" is the diameter of the tire fit. Unit of measurement - inch
The number "82" is the so-called load index, which determines how much weight can put pressure on one such tire. In this case, it is 470 kgf
Article "T" - symbol top speed for which the tire is designed. In this case, it is one hundred and ninety kilometers per hour.
It is worth noting that the recommendations that are given by the manufacturer did not appear out of the blue. All data has been checked by engineers in theory and tested in practice. And you can see different tire tests that have been tested online. So these parameters rims and tires are ideal for a combination of several factors, including stability vehicle on the road, the handling of the vehicle, the cross-country ability of the vehicle and the safety level of the vehicle.
To make it more clear, we present possible options developments when some of the recommended parameters are not met. So, if the rim offset on the wheel is larger than the standard one, then it will cling to the brake mechanisms while driving, which can increase braking distances. If the rim offset is less than the recommended value, then this brings the value of the load on the hub bearings beyond the norm, and this can lead to their unexpected failure, which will lead to the unpredictability of the vehicle's trajectory, and this is a direct threat to the life of the driver and his passengers .
Violation of all other recommendations given by the manufacturer will also not lead to anything good. At best, this will increase the wear of parts of various assemblies, and at worst, it will seriously reduce the already not the best best level safety of a VAZ 2107 car. It is also allowed to install 5 "/2Jxl3 wheels with a rim offset of 25 - 30 mm on a VAZ 2107 car.
When giving recommendations in choosing certain tires for a VAZ 2107 car, the manufacturer proceeds from the conditions for ensuring maximum stability, controllability, patency and safety of a VAZ 2107 car. So, wheels with a long reach can touch the brake parts, and with a smaller one, they increase load on the hub bearings and can lead to unpredictable behavior of the VAZ 2107 car during emergency braking or in the event of a failure of one of the circuits brake system. High-profile tires can touch the body parts of a VAZ 2107 car at maximum suspension travel, and wide tires can rub against the side member of a VAZ 2107 car or its wing at large turning angles.
A tire with a lower load index may burst when the most loaded VAZ 2107 car hits an obstacle, and lowering the speed index is fraught with tire destruction at high speed.
Tires that can be installed on a VAZ 2107 car are divided into three types: summer tires, winter tires and all season tires. If the VAZ 2107 car is operated all year round, and the winter is snowy, then it is better to have two sets of wheels: with winter and summer tires. Winter tires are made of softer rubber, and narrow wavy slots are made on the tread - sipes. This allows the tire to better cling to the roughness of the coating and not “stone” at low temperatures. On the sidewalls winter tires the inscription "M + S", "MS" or the pictogram "snowflake" can be applied. The possibility of using studded tires in winter depends on the specific operating conditions of the VAZ 2107 car. It should be borne in mind that the studs are designed to improve the grip properties of the tire on slippery hard surfaces, such as ice or packed snow. In other cases, the spikes do not work, and on asphalt they even slightly worsen the grip of the tire with the road.
The use of winter tires on a VAZ 2107 car in summer leads to their intense wear.
All-weather tires for a VAZ 2107 car can be used all year round. They are distinguished from other tires by the inscription "All season" or "Tous terrain" on the sidewall. According to their indicators, they behave satisfactorily in various weather conditions, but at the same time they lose in summer technical indicators summer tires and winter tires.
The tread pattern on tires can be universal or directional, and is not regulated by the manufacturer's requirements. With a directional tread pattern, the inscription “Rotation” and / or an arrow are applied on the sidewall of the tire, indicating the direction of rotation of the wheel when the VAZ 2107 car moves forward.
It's safe to say that rims have always been a "stumbling block" for many owners. On the one hand, stamped standard wheels are quite cheap, unpretentious and durable, the right size of wheels is always on sale, both R13 and R14 can be bought without even leaving the regional center.
But something needs to be changed appearance car, repaint the body, carry out minimal tuning- and the desire to "put the casting" increases exponentially. In addition to beauty, fuel economy alloy wheels allow the owner to make a serious argument in favor of choosing the VAZ 2107 and even brag a little to the audience: they say, “I could buy a foreign car a long time ago, but as a patriot, you know, I put the central lock, casting, and continue to respect our auto industry.”
So, about the rims in order.
Wheel functions
- The disks transmit torque to the bus of the drive pair.
- The discs contribute to the uniform compaction of the tire along the entire length of its circumference, or around the perimeter.
- The disc ensures the correct location of the tire in the suspension, providing all the rigidity of the structure.
Disks are different, both in width and in diameter, (R 13, R 14, for the classics) by weight, by the number of holes for fasteners.
First of all, according to the production method, discs are stamped and cast. And the first question of a beginner “what disks to install” implies exactly the answer to this question. He is not so simple. Let's see why.
stamped discs
Their advantages are unpretentiousness, low cost, high wear resistance, as well as ductility. This means that if it falls into the pit, the disc can be crushed, but not split or broken. A bent disc is easy to straighten even with an ordinary hammer. Stamped rims are so cheap that cars don't take them off at night.
As for the shortcomings, the most important is a lot of weight, which affects acceleration, braking and inertia. The result is poor handling and higher fuel consumption. In addition, from a purely aesthetic point of view, all cars have the same face. Rust can also be a disadvantage, as factory paint is usually short-lived. Also, stamping should be well washed in spring and autumn, in order to avoid unnecessary noise and salt corrosion.
Alloy wheels
Casting is fashionable, cool, modern. In addition, such discs can be 20-30% lighter than stamped discs, because they are made from an alloy of light metals, they are less susceptible to corrosion, and more durable. The very technology of casting under low pressure increases the strength of products.
Outwardly, alloy wheels have an individual look, there are design bureaus that produce new forms and follow fashion.
Functionally, the ride on alloy wheels is smoother, acceleration is improved, and fuel consumption is lower.
But there is also a “reverse side of the coin”. disadvantage alloy wheels is an extension of their virtues. That is, when it enters the pit, the cast disk does not wrinkle like a stamped one. But under supercritical load, it simply bursts, splits - and its place is in the alloy processing shop, or in the trash.
This is due to the fragility of the disk. In addition, the casting cost is higher and the service life is shorter. An important disadvantage is the transmission of all shocks to the suspension, since the disk cannot absorb them with its own deformation. Therefore, before deciding which wheels to install, decide where and why you will drive a car.
When choosing a disc, the most important thing should be their compliance with the car model. So, installing disks under a low profile will not suit summer residents, and installing heavy and durable disks will not save on fuel consumption. If you missed the choice of size, then the wheel on the corners can “short” the fender liner, or, which is completely offensive, cannot be installed at all.
What quantitative parameters do standard disks for the classic VAZ 2107 have?
More complete labeling, thus, looks like 5x13, or 5.5x13.
In simpler terms, if the offset is positive, then it will seem that the disk is immersed, or "drowned" in the arch.
If the overhang is negative, then it will seem that the disk itself protrudes from the wheel arch, and the seat of the disk itself is recessed deep enough.
For all VAZ classics standard reach is +29 mm.
If you don’t know which offset you should get, then the Leninist rule “better less is better” is perfect here, since if the offset is too large, the wheel can rest against the fender liner, despite the correctly selected radius. The standard deviation is about 5 mm on either side, so for the VAZ 2107 it will be from +24 to +34 mm. At the same time, it must be remembered that this parameter only works for a certain width of the disk, if you want to install wide disks, then you need a smaller overhang and vice versa.
- Wheel bolts must be M12 with a diameter of 1.25 mm. Standard drilling is designed for this size.
- In case of wheel installation bigger size R 14 instead of the stock R 13 will have to install a lower profile tires, such as 55-60 mm, because there is "less room" on the tire. The limit of love for a low profile can be the following photo. Before deciding on such a bold act, you need to understand that leaving the center of a large city is categorically contraindicated for such a car.
In conclusion, I would like to say that a compromise can be winter tires for stamping, and a summer kit for casting, for beauty lovers. And for lovers of benefits - on the contrary, since fuel consumption is higher in winter, and the chance of getting into a pit is less than in summer. In addition, there are fewer out-of-town trips in winter, and the roads there are smoother than in summer.
The choice of wheels on the VAZ-2107 for car owners is important. Properly selected tires provide stability and controllability, fast acceleration and easy braking, smooth running and safety on the road. They take the torque from the motor of the car and contribute to the movement of the vehicle by traction.
A brief overview will help you figure out which wheels and tires to put on the “seven”, how seasonality affects the choice of wheels and what type of tread is best for different weather conditions.
When choosing discs for the VAZ 2107, strength, balance and wheel sizes are taken into account. The main parameters that are paid attention to when buying are the radius and width. The manufacturer completed the machine regular disks marked 5Jx13H2 ET29. The numbers and letters represent the following:
- “5” is the width of the rim, in inches;
- “J” – profile;
- “13” – disc rim diameter, in inches;
- "H2" - the number of humps on the wheel rim;
- “ET” - letter designation of the wheel rim offset;
- “29” – rim offset, in mm.
Valid disk parameters look like this:
- The number of holes and the diameter of the circle on the wheel disks (bolt pattern) - 4x98 mm.
- Hub diameter - 58.5 mm.
- Rim diameter – 13-15”.
- Wheel offset - 15 - 30 mm.
- The recommended width is 5.0-6.0”.
- Fasteners - M12x1.25.
It is better not to put wider disks on the “seven”. Under them, you need to choose the appropriate tires. They are larger in parameters than the fender liner and can touch or rub against the structural elements of the car.
Consequences of installing wide wheels:
- Rapid contamination of the side parts of the machine.
- When turning the wheel, they rub against the side member and wings of the body, which leads to intense wear and damage to the car.
- While driving, tires can touch the brakes, and this is fraught with an accident on the road.
- Increased wear on the wheel bearings, as they will bear more load.
Discs with a small rim overhang (the disc will protrude more outward of the car) are also not installed. The hub bearing at the same time takes most of the load, so it can quickly fail or jam.
Wheels are divided into forged, stamped and cast. In the "seven" steel stamped wheels are installed by the manufacturer. They have an average margin of safety, are inexpensive and have a long service life. The disadvantage of tooling is the need for periodic rust treatment, which leads to a rapid loss of appearance.
Particular attention is paid to the 4x98 bolt pattern. There are 4 holes on the rim for the mounting bolts with which it is attached. The diameter of the circle with holes is 98 mm. The distance between the centers of two closely spaced mounts for the VAZ 2107 is 69.3 mm. In the disks used on foreign-made cars, there is a bolt pattern - 4x100, the distance between the centers is 70.7 mm. When such imported equipment is installed on a VAZ, an error of 1.4 mm appears, due to which the disk is not fixed and is quickly damaged. Therefore, car owners use studs, elongated bolts, spacers and eccentrics as fasteners. Incorrect installation leads to unbalance and vibrations, the wheel falling out and further accident.
Parameters of standard tires
The base tires on the VAZ 2107 have the designation 175 / 70R13 82T, which stands for:
- “175” – tire profile width, in mm;
- “70” – ratio of profile height and tire width, in %;
- “R” – radial type;
- “13” is the diameter of the rubber fit, in inches;
- “82” - tire tonnage, 470 kg;
- "T" - the highest sustained speed, 190 km / h.
except standard size tires R13 82T with a height of 70% to the width, the manufacturer recommends installing rubber with a width of 165 mm and a wheel size of 80R13 82T. Standard elements are low-profile, with a 1-ply steel cord breaker to reduce rolling losses.
When choosing, the following factors are taken into account:
- Tires with a lower profile often result in rim defects when hit in a pit.
- Rubber, which has a larger profile, does not fit into the wheel arch and constantly rubs.
- Non-standard profile height affects rim length and speedometer speed measurements.
- The maximum wheel size can be larger than the standard one, for example, R14, R15 and R16 when upgrading the car and converting it into an SUV or sports car, but the tire parameters must match the bolt pattern and offset, not touch when cornering.
- An underestimated speed index leads to the destruction of rubber at high speeds.
- Tires with low load burst when hitting an obstacle with a full load of the car.
The choice of tires for the season
Rubber on the VAZ 2107 is divided into summer, winter and all-weather. For year-round use, drivers use all-season tires with the All season designation or Tous terrain lettering on the side. The behavior of the "seven" on such rubber is satisfactory in all weather conditions, but in summer they are worse summer tires, in winter - winter.
Winter tires are made of soft rubber, the tread has narrow wavy sipes for better grip. pavement. At negative air temperatures, they do not petrify. Studded tires are designed for driving on slippery hard roads (ice, packed snow). When driving on asphalt, they are not used. The use of winter options in the summer season leads to intense wear. The designation of the tires is applied to the sidewall, the markings are “M + S”, “MS”, the “Snowflake” pictogram.
Summer wheels are stiffer due to the smaller rubber composition. They are characterized by increased wear resistance, but at low ambient temperatures they have bad grip coated. The lugs of the tread are larger than those of winter tires.
The tread pattern is universal and directional, it is not regulated by the manufacturer. Tires with directional tread have a Rotation designation on the sidewall and an arrow that indicates the direction of travel while moving forward.
Air temperature affects tire pressure. In hot weather, it rises and when driving at high speeds it reaches 3-4 atm. If there is a cut or bulge in the rubber, it can explode. The most dangerous explosion of the front tire, because it will lead to a skid of the car.
Before installing the equipment on the VAZ-2107, the driver must know what pressure in the wheels needs to be maintained.
The nominal pressure in tires depends on their typical size. For the front wheels 165 / 80R13 it is 1.6 atm, rear - 1.9 atm. For rubber 175 / 70R13, the pressure of the front tires is 1.7 atm, the rear - 2 atm.
Wheels are always of great interest. Stamped can always be bought at any auto shop. Their reliability and durability is time-tested. However, it is only necessary to slightly change the appearance of the car, and you no longer want to go back to such models. There is a desire to install alloy wheels for the VAZ 2107. They have a positive effect on fuel consumption, make the trip more comfortable and safe.
Functionality of rims
In front-wheel drive cars, with the help of a disk, revolutions are transmitted to the drive pair. The cover sits tight on it. The front suspension becomes stiffer due to the correct positioning of the tire.
Wheels for a VAZ 2107 car are available in several versions. They differ in certain parameters:
- Width.
- diameter.
- Mass.
- Number of mounting holes.
It is allowed to install disks of size R13, R14 on any VAZ 2107 car. According to the production method, it can be both stamping and casting.
Beginners always ask the question, which discs are better to put on a seven? It will not be possible to answer it in one sentence. Each type has its own advantages and disadvantages.
stamped
Main advantages:
- Low cost.
- Unpretentiousness.
- Excellent wear resistance.
- Plastic.
Stamping, falling into the pit, does not break or crack, only creases. You can straighten the dent with a regular hammer.
The main disadvantage, perhaps, can be called a large mass. Because of this, the car accelerates for a long time, it has a large inertia, and the braking distance increases. All these qualities affect the controllability of the car, increase fuel consumption.
If we looked at the stamped wheels on the VAZ 2107 from the point of view of aesthetics, we can see that they all look the same.
The factory coating is usually of poor quality, so the paint quickly begins to fly off and the surface becomes rusty. So that the stamping does not make noise, does not corrode with salt, it must be constantly washed.
cast
Today the best discs on the VAZ 2107, cast products are considered. They have recently become fashionable and quickly gained great popularity. Light alloys are used for their production, so they weigh 30% less than stamped counterparts.
Alloy wheels are highly durable and almost never rust. In addition, their appearance has many differences. Designers are engaged in the aesthetics of the product, giving it an original look.
If we consider cast models in terms of functionality, certain advantages immediately become noticeable:
- Fast acceleration.
- soft movement,
- Reducing fuel consumption.
For all their merits, alloy wheels are not without negative qualities. After a strong blow, for example, when flying into a deep hole, it will not crumple, but simply burst. These parts are not repairable.
The cost of cast structures is always higher than ordinary stamping, and the service life is much shorter.
Any shock is transferred to the suspension, since alloy wheels cannot absorb external influences with their own deformation. Which discs to put on the VAZ 2107, each driver decides individually, taking into account future operating conditions.
When choosing, it is very important to consider the model of the car. For example, wheels for low-profile tires are not suitable for summer residents; heavy structures will increase fuel consumption.
Wheel sizes VAZ 2107
Four mounting bolts are used to fasten the products. The holes for them are located in a circle with a diameter of 98 millimeters. For bolts, holes with a diameter of 12.5 millimeters are drilled.
In order for the disk to be freely placed on the hub, it is made central hole 58.5 mm in diameter. It is along this hole that its orientation occurs. The bolts only press the flange against it.
When installing an alloy wheel, you may need to use an adapter ring. Sometimes without such an additional part it is impossible to create an exact alignment of the hub and the surface of the disk. The ring can be freely bought at any auto shop.
Removal, or departure of the disk on the VAZ 2107 is usually equal to 29 millimeters. This term refers to the distance formed between the mating surface of the disk after installation on the hub, with a conditional plane passing through the center of the disk rim.
That is, when the offset is positive, it seems that the element has gone deep into the arch. With a negative value, it seems to come out of the arch, it seems that it is too deeply recessed in the seat.
Experts advise to make a flight within the normal range. If the overhang is too high, the wheel may begin to touch the fender liner. It is allowed to withstand a deviation of 5 millimeters in any direction. In other words, on the VAZ 2107, the departure can be in the range of +24 - +34 mm.
Moreover, this parameter is designed only for a specific disk width. To fit a wider model, it is necessary to withstand a smaller overhang.
