Too much tire pressure leads to premature wear of the center of the tread, which is accompanied by reduced traction, a "harsh" ride and tire failure due to impact loads.
Regularly inspect your tyres for cuts and bulges, especially on the sidewalls. Nails and glass caught in the tread should be removed before they cut through the rubber. If, after removing a nail, you find that the hole is already through, you should replace it to mark the puncture, immediately replace the wheel and take the damaged tyre to a tyre shop. In many cases, you can simply install an inner tube of the correct size and type inside.
Periodically, remove the wheels and clean them from dirt inside and out. Inspect the wheel rims for signs of corrosion and other defects. Light alloy wheels often become deformed when hitting a curb, and steel wheels can become warped and rusty. Very often, when defects are detected, the only way out is to replace the wheel.
Wheels must be properly balanced to prevent premature wear and damage to suspension and steering components. Wheel imbalance is indicated by strong vibration of the body when driving, especially noticeable through the steering wheel. Likewise, damage or defects in steering or suspension components can lead to premature wear of tires. Wheel balancing usually does not eliminate vibration caused by these reasons.
Overall tire wear is largely determined by your driving style - hard braking or acceleration, as well as high-speed turns, will cause tires to wear faster. Wheel rotation helps to even out wear, but is only permitted if the same type of tires are used in the front and rear.
Uneven wear of the front tires may be caused by incorrect wheel alignment. Front wheel alignment should be checked and adjusted according to the manufacturer's instructions.
It is best not to mix different types of tires on the same machine. The only acceptable combination is to have bias-ply tires on the front axle and radial tires on the rear axle. When using tires with different cords, the fabric-cord radial tires should go forward and the steel-cord radial tires should go backward.
