VAZ 2109 - 5-door front-wheel drive hatchback, produced at the Volga Automobile Plant. In comparison with the "related" VAZ-2108, the model was positioned as more "solid" and was intended for a family man, since it was endowed with a less expressive appearance and 5 doors. For the characteristic contours of the body, the car was often called a "chisel".
"Nine" represents class B. The main competitors of the model are Skoda Felicia and Renault 19. The Russian car lost to its "classmates" in reliability, but was much more affordable.
The peak of popularity of the VAZ 2109 fell on the 90s. Then the production of the model opened in Belgium and Finland. However, soon the release of the "nine" in these countries stopped. In 2004, the model was discontinued at the Volzhsky Automobile Plant. Until 2011, the VAZ 2109 was produced in Ukraine.
Sales of the "nine" started in 1987. Externally, the model almost completely repeated the VAZ-2108, differing from it only in the number of doors. The car has remained the same style: angular body features, a relatively slight slope of the windshield, a large protruding bumper and noticeable rectangular headlights. Despite the similar design and dimensions, "nine" and "eight" were fundamentally different machines. The width of the front doors in the VAZ-2109 was reduced by almost 250 mm. In the exterior of the model, the swiftness of the lines was guessed, but the sportiness became much less.
The salon of the "nine" turned out to be extremely practical. At the same time, the developers managed to increase the comfort indicators. The car has a "low" dashboard, which has become more convenient. The front seats received head restraints, and the upper belt anchorage points were height-adjustable. Padded upholstery and fabric seats, available as an option, added prestige to the model. The folded rear seats were made from the VAZ-2109 to resemble a station wagon. The cabin had ventilation and heating systems.
The first modernization of the car took place in 1989. The front part of the body was slightly refined. The whole restyling consisted in the transition to the "long" front fenders, replacing the "short" version. In 1990, the model received a new 1.5-liter engine (72 hp). The upgraded version was named VAZ-21093. It was this modification that became the most popular. By the mid-1990s, 1.1- and 1.3-liter engines were excluded from the line of power units. Engines were combined with 5-speed gearboxes.
Another restyling of the model took place in 1995. They stopped melting the radiator grill. The last cosmetic improvement of the VAZ-2109 happened in 1997. More than the car has not changed.
Sizes of discs and tires
Regardless of the modification, the "nine" could be equipped with the following types of tires and disks:
- wheels 5J by 13 ET40 (5 - width in inches, 13 - diameter in inches, 40 - positive offset in mm), tires - 165 / 70R13 (165 - tire width in mm, 70 - profile height in%, 13 - rim diameter in inches);
- wheels 4.5J for 13 ET40, tires - 155 / 80R13;
- 5.5J wheels for 13 ET40, tires - 175 / 70R13;
- wheels 5J for 14 ET40, tires - 175 / 65R14;
- 5.5J wheels for 14 ET37, tires - 185 / 60R14;
- wheels 6J for 14 ET35, tires - 185 / 60R14.
Other characteristics of the VAZ-2109 wheels:
- PCD (drilling) - 4 by 98 (4 - the number of holes, 98 - the diameter of the circle on which they are located in mm);
- fasteners - M12 by 1.25 (12 - stud diameter in mm, 1.25 - thread size);
- central hole diameter - 58.5 mm;
- tire pressure - 1.9-2 bar.
Any owner of a VAZ-2109 sooner or later has a question: what is the bolt pattern on the disks of their car? Usually they ask it at the moment when they begin to think about replacing these important wheel elements that ensure traffic safety and the image attractiveness of the vehicle.
In general, the concept of "bolt pattern" means the distance from the center of one mounting hole of the disc to another. For the most part, this parameter is the same for all products of the Volzhsky Automobile Plant, but in general no standard values have been developed. Therefore, the bolt holes on the hubs are not the same for different manufacturers.
Razorovka - dimensions
If you buy discs with a lower ET value, then the grip on the road surface will increase significantly, which means:
- controllability will deteriorate;
- fuel consumption will increase;
- wheel bearing wear will accelerate.
Can I put 4 × 100 discs
This option can often be seen on the VAZ-2109. However, in reality, this decision is not correct.
The problem is that the standard bolt pattern of the model in question differs relatively slightly from the factory one. It seems to many that these couple of millimeters do not matter. However, a 4 × 100 disc cannot be properly secured with conventional bolts. There is a thickening (under the head) on them - it is this that does not allow the fasteners to be completely screwed in. Moreover, if you try to do it by force, you will most likely rip off the threads in the hub.
We will figure out how to choose the right tires and wheels for your VAZ 2109. We will not touch on specific manufacturers, we will just make an overview, thanks to which you will be well oriented in tires and wheels by their appearance and markings.
On VAZ 2109 cars, 13-inch discs are used. Therefore, if you saw R13 on your tires, then this is just an indication of the diameter of the disc.
However, in addition to the diameter of the disc, there are other important parameters:
Disc diameter - everything is clear here, this is the diameter inside the disc on which the tire will be installed.
Rim Width - the width inside the rim that the tire will be mounted on.
ET-disc outage. A parameter showing how deep the disc will be sunk into the car's arch.
PCD - the number of mounting holes and the distance between them.
DIA is the diameter of the center hole of the wheel disc.
There are five important parameters, and each of them must not be forgotten. Standard marking
VAZ disk is as follows:
5Jx13H2
And that's all. In this case, the unspecified parameters are as follows:
Wheel overhang 40 mm
PCD 98/4 mm
DIA 58.5 mm
The diameter and width of the disc are important because if you do not take them into account, then the standard VAZ rubber will not fit on this disc. Departure is important in how the wheel will look on the car: Departure<40 мм — колесо будет утоплено в арку, >40mm will stick out from the side of the car.
PCD is very important, if you take a disc with any other PCD, then you simply cannot screw it to the hub. Either the number of holes will be wrong, or the distance between these holes is not exactly 98 mm. The bolts will not fall into the holes on the hub, and if they do, the disc will warp during compression. There are many discussions on the Internet about this. For example, disks from Renault Laguna with a diameter of 13 inches have a PCD of not 98 x 4, but 100 x 4. This means that the distance between the holes in the disk is not VAZ 98 mm, but 100 mm. The subject of the dispute is as follows: some argue that this is all nonsense, carefully squeeze the bolts when installing crosswise and go to health. Others argue that this is not worth doing - the disc will become uneven and the car will shake when driving. We are all different people, and what is good for one person may be bad for another. One will drive with a broken suspension on such discs and not pay attention to the fact that the car shakes. Another person will notice even minor vibrations when the vehicle is moving. The reason for the vibrations is as follows: due to an uneven fit (even fractions of a millimeter play a role), a wheel on a disc with a PCD 100 on a hub with holes of 98 x 4 rotates not in a circle, but in an ellipse. That is, the center of the axle of the car will not coincide with the center of the disc, but here the supporters of 100 x 4 discs will again object - there are special bolts
with eccentrics:
It makes sense to use eccentric bolts if you install alloy wheels. The reason is as follows: a stamped used disc in good condition on a VAZ 2109 costs about $ 10, and one eccentric bolt costs about $ 2-3. That is, it turns out that four eccentric bolts cost the same as the disc itself.
Now let's get into the tires. The overwhelming majority of tires produced by the industry today
tubeless radial. The explanation of the type designations on the bus is given below.
Let's look at a few examples. Example # 1:
The picture shows a tire with a diameter of 14 inches, a width of 185 mm and a height equal to 185 mm * 0.7 (70% of the width of the tire). This is winter tires, since there is an M + S inscription, it is also tubeless. The arrow shows the direction of rotation of the wheel. This is also important, because if you put it not on the arrow, then the rubber will wear out more. Here are a couple more typical tire designations:
Is it possible to install R14 wheels (or even more) on the VAZ-2109? How will this affect the behavior of the car and will there be problems with the traffic police?
Wheels with a tire diameter of 14 inches can be installed on the "VAZ" "Samara". But at the same time, other dimensions of the disc (width and offset) should not exceed certain values, otherwise in turns and at maximum load of the car, the wheels will touch the wheel arches and suspension elements. The "bottleneck" of the VAZ-2108, -09, -099 is the rear arches and suspension, which often "conflict" with oversized wheels.
For Samar, stamped steel discs 5 or 5.5 inches wide with an offset (parameter ET) of 38 - 40 mm are suitable. Light-alloy wheels can also be installed. In this case, the disc width should be 6 inches and the ET should be 33 or 35 mm. In this case, a tire with a dimension of 175/65 R14 is used - for example, such as in the factory configuration of a VAZ-2110 or Skoda Fabia. It is possible to use tires with a width of 165 and 185 mm.
In addition, installation on "nines" and "eights" and 15-inch wheels is allowed - provided that discs with ET equal to 30 - 35 mm are used, and with sufficiently low-profile tires 185/55 R15. The "eights" also drive with 195/50 R15 wheels. But even more "cool" tires 195/55 R15 and 205/50 R15 are installed only on the front axle or simultaneously with the modification of the suspension or wheel arches.
Based on the operating experience of the "overdone" "Samar" we can say that the recommended tire size for R15 rims is 195/50, and for R14 - 185/60.
Let us also remind that for any "VAZ" disks the diameter of the circle of the location of the four mounting bolts (PSD) is 98 mm, which is coded as 4x98 in the catalogs. The diameter of the central hole in the discs for Togliatti machines should not be less than 58.5 mm.
Fitting low-profile tires improves the vehicle's handling when maneuvering and speeds up cornering. Low tire beads are less crumpled under lateral loads on the tire, and the steering wheel becomes "sharper", and the car deviates less from the trajectory. But such wheels absorb defects in the roadway worse and transfer more shock loads to the body when driving over bumps. In addition, a tire with a low profile, even when driving through a pothole at low speed, is easy to "punch" to a disc, the edge of which can be crumpled up to complete failure.
It is worth noting that road traffic regulations prohibit the use of vehicles with tires that “do not fit the vehicle model”. However, the practice of operating tuned VAZs testifies that traffic police officers usually have no complaints about 14-inch wheels - obviously, due to the fact that “14” disks at the plant are equipped with “Lada-2110”, similar in chassis to “eights” and “ nines ". But with fifteen-inch wheels, the likelihood of "running into" trouble during the inspection is higher.

If you look at the VAZ 2109, the size of the wheels is not very impressive in its appearance. The discrepancy between the small diameter of the wheel and the high profile of the rubber immediately catches the eye. Therefore, car enthusiasts often think about which discs are best suited for a comfortable car ride.
Which discs to choose?
Wheel disks perform the following important functions:
- transmission of torque;
- sealing the tire along the inner perimeter of the touch;
- precise placement of the wheel in relation to the suspension and body.
1.Decoding the characteristics of rubber
First of all, you need to figure out how to decipher the characteristics of rubber, which are usually applied to the side surface of the tire. Usually the size is designated 175/70 R13. From this entry it follows that the tire width is 175 mm; 70 - tire profile height (% of width). In this example, the profile height is determined as follows: 175x0.7 = 122.5 mm.
Let's translate the diameter into a general dimension: d = 13x25.4 = 330 mm. As a result, the outer diameter of the tire will be: D = 330 + 122.5x2 = 575 mm.
For 14 ″ disks, the basic dimensions can be as follows: 185/60 R14 and 175/65 R14.
2.Features of using wide and narrow wheels
Each size has its own advantages and disadvantages. A wider tire increases the grip patch. As a result, braking is improved and the car becomes more controllable. If you use an alloy wheel, the wheel becomes much lighter. The car runs more steadily on a straight line, but dives worse into a turn. The wider the tire, the more likely it will aquaplane on the fast lane.
With a low profile, the rubber is more resistant to deformation when cornering. But then the bumps from the bumps in the road become stronger. They are transferred directly to the suspension and bodywork. As a result, the wear of the chassis increases and the ride comfort is impaired.
In winter, a wide tire is less able to push through a thin layer of snow or water, which worsens traction. A tall tire is better at smoothing out impacts from uneven road surfaces, but when cornering sharply at high speed, it can “break”. It folds to the side or jumps off the disc. The disc can also touch the asphalt and this creates a tip over hazard.
The use of 15 ″ discs is prohibited by the manufacturer and the vehicle may not pass the technical inspection. If such discs are used for VAZ 2109, wheel sizes are recommended with a width of 185 mm and 195 mm. In the latter case, the wide tire is already starting to touch the arch. For a wide disc, it is required to increase its overhang, which leads to overload and rapid bearing failure.
Changing the outer diameter of the wheel
For VAZ 2109, they usually try to take the recommended wheel sizes or a little more, as far as the design of the arches will allow. Fitting a wheel with a smaller diameter to a car reduces noise and increases acceleration dynamics. As a result, there are more shortcomings: the vehicle's ground clearance decreases, the maximum speed decreases, the speedometer starts to "twist", and the grip deteriorates.
The maximum wheel width on the VAZ 2109 is 195 mm. The next dimension is 205 mm and this is already exceeding the limit. The wide tire starts to graze on the arches and need to be trimmed. Numerous videos and photos on the Internet show that this is a rather difficult job.
An increase in the outer diameter of the wheel, if it does not interfere with driving, eliminates all the above disadvantages, but then acceleration deteriorates. The load on the steering wheel also increases and this is noticeable since there is no power steering.
Other settings
In addition to the basic characteristics of the tire and wheel, there are other important indicators that must be considered. One of these is wheel offset, which is the distance from the wheel hub to the middle of the disc.
You can also increase the vehicle's ground clearance by using spacers under the shock absorbers. You can install them yourself. Then the overhang can be made smaller, but its deviation from the recommended leads to a change in the load on the hub bearing. This will lead to a decrease in its resource and affect the controllability of the machine.
The overhang can be made less than recommended for wide discs. If the disks are narrow, then you can take more. For the correct choice, it is advisable to seek help from a specialist, from whom you will receive precise instructions on what parameters are needed. When purchasing discs, it is imperative to accurately select the installation dimensions for the mounting bolts and nuts (PCD). If the choice was made even with a small mistake, a disc can be installed on the hub with a slight PCD deviation, which is not noticeable visually. Then some of the bolts will fit exactly, while others will be skewed. Such a wheel will begin to "eight", and the nuts spontaneously unwind.
Conclusion
Deviations in tire and rim sizes from the standard for your car have features that should be taken into account when driving. The choice of one or another version of the VAZ 2109 wheel depends on its price and the preferences of the motorist.
