It is very important to keep your tires in good condition and at the correct pressure - a tire failure at any speed is very dangerous. The type of driving affects the wear of your tires - hard braking and acceleration, or fast cornering will accelerate the wear of your tires. As a rule, the front tires wear faster than the rear ones. Swapping your tires (front to rear, "rotating" your tires) will result in more even wear. However, if necessary, you can change all four tires at once! Remove nails or stones that have become lodged in the tread. If the tire starts to leak water after removing a nail, insert a nail to mark the puncture. Then immediately replace the wheel and repair the punctured tire.
Check your tires regularly for damage in the form of cuts or bulges, especially in the sidewalls. Remove the wheels periodically and clean the inside and outside surfaces of dirt. Inspect the inside sidewalls of the wheel rim for signs of rust, corrosion, or other damage. Lightweight wheels with alloy wheels are easily damaged when driving over a curb; steel wheels can also become bent. Installing a new wheel is often the only way to repair serious damage.
New tires should be balanced in the installed position, but may need to be rebalanced as they wear. Unbalanced tires will wear faster, as will steering and suspension components. Wheel imbalances usually show up as vibrations, especially at certain speeds (usually about 80 km/h). If this vibration is felt only through the steering, then it is likely that only the front wheels need to be balanced. However, if the vibration is felt throughout the entire vehicle, the rear wheels may also be unbalanced. Wheel balancing should be performed at a service station.
Tread depth - visual inspection
1. New tyres have tread wear markers (B) that will appear when the tread depth reaches approximately 1.6 mm. The marker positions are indicated by a triangular mark on the sidewall of the tyre (A) (refer to the accompanying illustration).
Tread depth - manual control
1. Tread wear can be monitored with a simple, inexpensive device known as a tread depth gauge (refer to the accompanying illustration).
Tire pressure monitoring
1. Check tire pressure regularly when tires are cold. Do not adjust tire pressure. Do not adjust tire pressure immediately after using the vehicle (refer to the accompanying illustration).
Tread wear
Lateral wear
Insufficient pressure (wears out on both sides)
Underinflation causes the tire to overheat because the cord will bend too much and the tread will not sit properly on the road surface. This will cause loss of traction and excessive wear, not to mention the risk of sudden tire failure due to increased temperature.
Check and adjust pressure.
Incorrect wheel alignment (wears out on one side)
Repair or replace suspension parts.
Difficult movement on the turn
Slow down!
Central wear

Pumping
Overinflation causes rapid wear of the central part of the tyre tread, as well as reduced traction and increased risk of tyre failure.
Check and adjust pressure.
If you occasionally need to inflate your vehicle's tires to a pressure higher than specified for the maximum load rating or high speed to be maintained, be sure to reduce the pressure back to normal afterward.
Uneven wear
Front tires may wear unevenly due to wheel misalignment. Most service stations can check and adjust the wheel alignment for moderate loads.
Incorrect camber or caster angle
Repair or replace suspension parts.
Faulty suspension
Repair or replace suspension parts.
Unbalanced wheels
Balance the tires.
Incorrect alignment
Adjust the front wheel alignment.
