Wheel sizes on Oka: how to choose tires and wheels for VAZ-1111 and 11113

Small but nimble VAZ-1111 "Oka" - a legend of the domestic automobile industry, which still travels the roads of Russia and the CIS countries. Despite its compact dimensions, the choice of wheels for this car requires attention: the wrong size can lead to friction on the fender liners, poor handling, or even suspension failure. In this article we will figure out what tire and wheel sizes suitable for Okie different years of production, how to choose the right tires for winter and summer, and also what to consider when tuning the wheelbase.

Feature Okie - its miniature size. Standard wheels here are not just a design element, but part of the design that affects ground clearance, dynamics and even fuel consumption. For example, increasing the diameter of the rims by 1 inch without adjusting the tire profile can lead to touching the wheel arches when the vehicle is fully loaded or on uneven surfaces. And incorrect tire pressure will accelerate wear on the suspension, which Oke and so it does not differ in its safety margin.

Standard wheel sizes for VAZ-1111 and 11113

Factory wheel parameters for Okie depend on the model and year of manufacture. Basic version VAZ-1111 (1988–2006) and its modification 11113 (with 0.75 l engine) are equipped with wheels of the following sizes:

• 🔧 Drives: 12×4.0J, departure (ET) +40 mm, drilling 4×98 (analogue 4×100 with adapters).
• 🚗 Tires: 135/80 R12 or 145/70 R12 - depending on the year and configuration.
• ⚖️ Pressure: 1.8–2.0 atm front and 1.9–2.1 atm rear (for even wear).

Important: on Oku with engine 11113 (volume 0.75 l) tires were sometimes installed 155/65 R12, but this required modification of the arches. Such wheels improved traction, but increased the load on the transmission. If your car was manufactured after 2000, check the nameplate on the door pillar - the permissible dimensions are indicated there.

Compatibility table for tires and wheels for Oka

Below is a table with proven dimensions that can be installed on VAZ-1111 without modifications. The data is valid for the standard suspension and standard arches.

Tire size	Rim Width (inches)	Reach (ET, mm)	Notes
135/80 R12	4.0J–4.5J	+35…+45	Standard size for most modifications.
145/70 R12	4.5J–5.0J	+35…+40	Improves stability, but may chafe when fully loaded.
155/65 R12	5.0J	+30…+35	Requires rolling out arches or installing spacers.
165/60 R12	5.0J–5.5J	+25…+30	Only for tuned versions with modified suspension.

⚠️ Attention: When installing discs with a smaller offset +35 mm the load on the wheel bearings increases. This can cause them to wear out prematurely, especially on rough roads. If you select discs with ET 25–30, be sure to check the bearing play every 10,000 km.

How to choose winter and summer tires for Oka

Due to the light weight Okie (about 650 kg) specific requirements are imposed on tires:

• ❄️ Winter tires: Optimal choice - 135/80 R12 with deep tread (at least 8 mm). Studded tires are suitable for ice, but on asphalt they reduce handling. For a snowy winter, it is better to take Velcro with a soft composition.
• ☀️ Summer tires: 145/70 R12 Provides better grip on dry surfaces. Avoid tires that are too wide (eg 165/60) - they will increase fuel consumption and steering load.
• 🔄 All-season: Possible, but not recommended for regions with harsh winters. If you choose this option, give preference to models marked M+S and speed index not lower T (190 km/h).

Tip: when buying tires for Okie pay attention to load index. Enough for this car 62–65 (maximum load 275–290 kg per wheel). A higher index is unnecessary and will only increase the price.

Is it possible to install larger diameter wheels?

Many owners Okie want to enlarge the wheels to improve appearance or maneuverability. However, there are nuances here:

1. R13: Theoretically, it can be installed, but hubs and brake discs will need to be replaced (for example, from VAZ-2108). You also need to roll out the arches. Such tuning will cost 15–20 thousand rubles.
2. R14: It is possible only with a complete rework of the suspension (installation of springs from VAZ-2109, change of levers). Without modifications, the wheels will cling to the fender liners even on a flat road.

⚠️ Attention: Increasing the wheel diameter by more than 1 inch without changing the gear ratio of the main pair will lead to loss of dynamics and increased load on the engine. For example, when moving from R12 on R13 the speed on the speedometer will be reduced by 5–7 km/h.

What happens if you install R13 wheels without modifications?

When installing wheels 155/70 R13 on standard suspension Okie the following will happen:

1. The tires will touch the front fender liners when turning the steering wheel.

2. The load on the shock absorbers will increase, which will lead to their leakage after 5–10 thousand km.

3. Fuel consumption will increase by 0.5–1 l/100 km due to the changed gear ratio.

4. The speedometer will lie at 10–15 km/h (show lower speed).

Which wheels are suitable for Oka: steel vs casting

When selecting disks for Okie It is important to consider not only the size, but also the material:

• 🔩 Steel wheels: Standard option, cheap and repairable. Weight - about 5–6 kg. Suitable for winter use, as they better withstand impacts from potholes. The downside is that they rust and require regular painting.
• ⚙️ Casting: 1–1.5 kg lighter, improves acceleration and braking. However, when subjected to a strong impact, they crack rather than bend. For Okie optimal diameter 12" with departure ET 35–40.
• 🌀 Forged wheels: The most durable and lightest, but cost 3–4 times more than casting. For Okie are not economically feasible - their price may exceed the cost of the machine itself.

When purchasing alloy wheels, check for a certificate - cheap Chinese analogues often have an imbalance, which at high speeds (from 90 km/h) causes vibration in the steering wheel. Also note center hole (DIA): for Okie it must be 58.1 mm.

Make sure the drill bit is 4x98 (or 4x100 with adapters)

Check the offset (ET) - optimally +35...+40 mm

Measure the center hole (DIA 58.1mm)

Inspect the disc for cracks or dents

Check the tire and wheel compatibility chart

Common mistakes when choosing wheels for Oka

Even experienced car owners sometimes make mistakes when choosing wheels. Here are the most common mistakes:

1. Ignoring departure (ET): Discs with offset ET 20 or ET 50 lead to uneven tire wear and wheel bearing failure.
2. Installing tires with the wrong speed index: For example, Q (160 km/h) instead of T (190 km/h). This is dangerous when driving on the highway.
3. Buying used tires without checking: On Oke Tread wear must be at least 3 mm (for winter - 5 mm). Check the production date (not older than 5 years).
4. Using tube tires: Tubeless tires are safer and lighter. Tubes are installed only on old wheels with damaged rims.

⚠️ Attention: If, after replacing the wheels, the car begins to wobble at speeds above 70 km/h, check immediately wheel alignment. On Oke Even a slight deviation in wheel alignment leads to strong vibration due to the short wheelbase.

Wheel tuning on the Oka: what is possible and what is not

Wheelbase tuning Okie popular among enthusiasts, but requires a competent approach. Here's what you can do without serious consequences:

• 🎨 Wheel painting: Use powder paint or liquid rubber. Popular colors are matte black, silver or metallic gold.
• 🔧 Installation of spacers: Spacers 10–15 mm thick will increase the track, improving stability. But do not exceed 20 mm - this will accelerate the wear of the ball joints.
• 🚘 Wide tires: Maximum - 155/65 R12 with rolling arches. Wider options will require suspension modifications.

What not to do:

• ❌ Install disks with PCD 4×100 without adapters - this will disturb the alignment.
• ❌ Use tires with a lower load index 62 - they will burst when fully loaded.
• ❌ Putting wheels with different tread patterns on one axle is prohibited by traffic rules (fine 500 rubles).

For radical tuning (for example, installing R14) you will have to change the brake system, springs and shock absorbers. Such modifications will cost 30–50 thousand rubles and will require registration with the traffic police as a design change.

FAQ: Answers to frequently asked questions

Is it possible to put wheels from a VAZ-2108 on the Oka?

Partially. Discs from VAZ-2108 (size 13×5.0J, drilling 4×98) will do, but you will need:

1. Install spacers 10 mm thick (extend to 2108 — ET 29, and on Oke needed ET 35–40).
2. Roll out arches or use tires 155/65 R13 with minimal tread.

Without modifications, the wheels will rub against the fender liners.

What pressure should Oka tires have?

Recommended pressure:

• Front wheels: 1.8–2.0 atm.
• Rear wheels: 1.9–2.1 atm (due to trunk loading).

With a full load (4 people + luggage), increase the pressure to 2.2 atm front and 2.3 atm behind. Check with a pressure gauge at least once a month - the valves are Oke often bullies.

Which tires are better for Oka: radial or diagonal?

Definitely radial. They provide:

• Better grip.
• Less heating during long driving.
• Longer resource (on average 40–50 thousand km versus 20–30 thousand km for diagonal ones).

Bias tires are cheaper, but can only be used at speeds up to 90 km/h. For Okie this is irrelevant, since its maximum speed is 130 km/h.

Is it necessary to balance the wheels on the Oka?

Yes, definitely! Despite the low maximum speed, an imbalance of even 10 grams will cause:

• Steering wheel vibration at speeds of 60+ km/h.
• Accelerated wear of wheel bearings.
• Uneven tread wear.

Balancing must be done at every seasonal tire change or after hitting a hole. The cost of the service is about 200 rubles. per wheel.

Is it possible to drive the Oka with different tires?

According to traffic rules (clause 5.5 Appendix to the Russian Traffic Regulations) it is prohibited to install tires on one axle:

• Various sizes.
• With different tread patterns.
• Winter and summer at the same time.

On Oke You can put different tires on the front and rear axles (for example, 135/80 R12 front and 145/70 R12 rear), but this will worsen handling. It is optimal to use the same set on all wheels.
