The legendary first all-wheel drive domestic SUV "Niva" won the hearts of fans of outdoor activities, and just car enthusiasts who often encounter problems on Russian roads, back in 1970. The monocoque body and comfortable interior, all-wheel drive, and independent suspension were a breakthrough not only in the domestic automobile industry. At that time, only the Jeep Wagoneer and Range Rover had such parameters - cars of a different class and for a completely different price. Subsequent modifications only increased the popularity of the model. Unpretentiousness in repair and operation distinguishes Niva favorably in the modern Russian car market, with an abundance of SUVs of other brands.
In the beginning, to reduce the cost of production, a prerequisite for putting a car on the assembly line was the use of units from VAZ passenger cars and, accordingly, VAZ wheels. With good cross-country ability on soggy loam and a relatively low price, this equipment has serious disadvantages:
- Poor handling on asphalt, even sideways drifts, which is inconvenient when operating in the city;
- Average cross-country ability for rough roads
Without any modifications, the Niva can be fitted with 27-28-inch tires with an offset of 35-48 mm. But even in this case, it is possible for the wheels to touch the fender liners up to the point of pinching the wheel in the arch in the following cases:
- Off-road driving with strong rolls;
- Overloading the car.
As a method of combating this phenomenon, VAZ offers special lifting kits that allow the wheel axle to be lowered to 40 mm. The kit includes:
- Reinforced longitudinal and transverse rods;
- Upgraded spring cups and spring spacers;
- Spacers for ball joint.
A radical method of significantly improving cross-country ability, saving fuel, and what to hide, raising the prestige of a car and specific “aggressive” tuning is the transition to 29-inch tires.
This method requires reworking the arches and, in some cases, lifting the suspension.
Let's take a closer look at the description of this process.
Lifting for Niva for 29 tires. Is it worth doing?
With the development of tuning, the opinion has become established that to install 29 tires on a Niva, it is enough to only trim the arches. The rationale for this decision is the fact that lifting has a negative impact on the main components of the car and reduces their service life, namely:
- Car drive – due to changes in the bend angle;
- Front suspension – due to the small stroke inherent in the design, the upper arm rests against the bump stop and limits the downward stroke of the suspension, which indirectly affects the camber of the wheels. A spacer for the upper ball joint further distorts the suspension geometry
- Rear suspension - due to the fact that spacers or larger springs change the position of the front axle.
Whether it is worth lifting, thereby reducing the life of the car, you have to decide for yourself. The reason for carrying out such an operation is the ground clearance, which is critical for operating conditions; lifting will give an additional 3 cm, for example, for the Niva Urban or Niva Chevrolet with a ground clearance of 190 and 205 mm, respectively.
In addition to mechanical changes, in order to achieve improved dynamics, especially during acceleration, it is advisable to raise the gear ratio from the standard 3.9 to 4.44. This is possible as a result of replacing gearboxes. The procedure is not mandatory, but desirable, as it will also reduce the load on the engine and clutch
Legal consequences of changing wheels or what the traffic police think
Driving a car with large wheels can be divided into two situations:
- Traffic on the highway . Rules of traffic regulations in the “Basic provisions for the approval of vehicles for operation” Section 5 “Wheels and tires” clause 5.4. The admission of vehicles with tires that do not match the vehicle model in size or permissible load is limited. As a result, the car owner may receive a warning or a fine of 500 rubles in accordance with Article 12.5 of the Code of Administrative Offenses of the Russian Federation, Part 1. Also, enlarging the wheels will lead to distortion of the speedometer, since the tachometer is structurally designed for a different diameter. This can lead to unknowing speeding and a fine of 500 to 2,500 rubles;
- Passing maintenance. A twofold situation is possible, but numerous Niva owners, when replacing the wheel diameter from standard to 29, usually do not experience difficulties during passage, with rare exceptions, which can be circumvented by returning standard tires for the duration of the passage.
Advantages and disadvantages of Niva as a result of installing 29 tires
Undoubtedly, the majority of car owners, in their desire to tune the Niva, want to achieve increased cross-country ability, because most often these are people who lead an active lifestyle, are fond of hunting or fishing, or simply live in a completely off-road situation, for example, farmers or rural residents.
The main parameters for assessing cross-country ability are:
- Clearance value;
- Overhang angles;
- Angles of roll and longitudinal passability;
- Angle of transverse static stability.
Installing 29-inch wheels will increase the ground clearance from the existing 228 mm to 232 mm, which is especially important for the Niva Urban with a low ground clearance of 190 mm. This is especially noticeable if you compare the location of the bumper
The difference in ground clearance is a result of switching to 29 tires.
The overhang angle is the maximum slope angle at which a car can move or drive on its own without the body touching. For Niva this is 32° on the way up and 37° on the way out. A larger wheel diameter improves the lift angle to 35, but due to a shift in the center of gravity, it reduces the departure angle to 33°. And the losses and achievements are not so significant as to seriously increase the level of cross-country ability.
The longitudinal flotation angle is the maximum possible angle that a car can overcome when moving from a slope to a horizontal surface. The roll angle reflects the opposite situation, leaving a horizontal plane with a downward slope. These figures are mainly affected by the wheelbase distance. But Niva drivers noted an improvement in driving down an inclined plane due to an increase in ground clearance as a result of replacing it with 29 tires.
The angle of lateral static stability determines the maximum trim of the vehicle from the central axis, which will be followed by a rollover on its side.
For Niva, this angle is 6.5°. The wheel diameter increased to 29 inches, on the one hand, should theoretically worsen stability indicators due to a shift in the center of gravity of the car; on the other hand, a larger wheel offset and wider tires compensate for this, especially on straight sections. In areas with a large curvature of the trajectory, the Niva loses its dynamics. Reduces the dynamics and deterioration of the parameters of the body's streamlining by wind flows when driving, by increasing the ground clearance.
The negative consequences of installing 29-gauge tires also include an increase in the load on the hub units due to spacers to increase the offset of the wheel rims. In order to slightly relieve the unit, double-row bearings are used in the steering knuckle. Such modernization increases the cost of the entire tuning.
The improved exterior of the body, increased cross-country ability with a general improvement in driving performance, exceeds the negative aspects of increasing the wheel diameter to 29 inches. Installing 31-inch wheels is undesirable, as it will require mandatory modifications to the suspension components.
Trimming the arches of a Chevrolet Niva has a similar algorithm.
Which tires are better to put on the Niva 2121 - MT or AT?
The choice of the type of off-road tires for a Niva M/T or A/T directly depends on the type of roads on which the car owner will drive more often.
A/Ts are good for rural conditions and occasional off-road trips. In conditions of viscous clay and swamps, these tires can simply get stuck. Each model has its own recommendations for the ratio of asphalt and off-road - 50/50, 60/40, 40/60, etc.
A/T tires
M/T are more suitable for unpaved and off-road conditions. They are characterized by high noise on asphalt roads, long braking distances on asphalt, comparatively worse handling when driving only on asphalt road surfaces, and wear out and wear out extremely quickly. These tires show excellent driving performance in mud.
Note!
M/T tires have low speed ratings, the highest of which is R. It is recommended to drive on these tires at speeds of up to 160 km/h.

Goodrich is not a friend of Simex. I rode hydrichs for a year without a head and the blockage was alive, I installed Simex at the first race and died. I started driving with my head. From my observations at competitions, too many cornfields on the 31st do not reach the finish line. If memory serves, then at the “Autumn Marathon” in the village of Kanevskaya, three cornfields on the 31st broke, if memory serves, then more cornfields with such there was no wheel size.

Duke's entire transmission is reinforced. Which is not difficult, but quite expensive for Niva.

Re: Niva tires 31-32 or 33
Grandfather, please tell me what exactly should be strengthened/modified on the field so that it runs on 31 wheels?
I read half of the forum on the field, and in the end my head is a mess. Can you tell me more details? Everything said is my opinion, not necessarily correct.

Re: Niva tires 31-32 or 33
The survivability of the transmission is not determined by size alone.
Mudrichi 33 is one thing, silvera is quite another. True silver 33 is actually 32 I apologize, I didn’t notice that this was already said in post 26

Solo , well, as a former novovod 29, you can’t strengthen anything much………….. it dies very quickly and most importantly at the wrong time

Try it. But they are heavy for the field. I have a mass of 2700 kg, and that is extremely flat at 1.2. It’s not clear up to 1.5 Atm; 3.0 or 1.5 Atm is pumped up. Silvers(stone) have a 6-layer side court. Niva is a ton lighter than me. Better narrower. Silvers 285s. Niva will be stunned by them. Really.
