Correct tire installation depends on a number of factors, which you need to check before putting on the wheels and tightening those lug nuts. Find out more about installing new wheels and tires safely and effectively below.
Check the Positions for Each Tire
Match each tire, whether directional or asymmetric to its axle and side of the car. Stack each tire by its appropriate wheel well, as race car pit crews do.
Install the Newest Tires on the Rear
Put the newest pair of tires on the rear axle, where they will maintain steering control if your car hydroplanes upon hitting glare ice or water. Alert the tire shop mechanic if your car takes 2 different sizes of tires. The smaller ones should never be put on the rear.
Check the Rotation Indicators
Directional and asymmetric tires have direction of rotation indicators marked on the sidewalls. Install the tires according to the rotation information provided.
Install the Tires and Wheels
Hand-tighten the lug nuts on each wheel when first installing them on the car, to ensure they are aligned correctly, then tighten with a lug nut wrench. Tests with the disc brakes and steering need correct wheel alignment. Check the wheel torque after driving a few miles, as they nuts will lose tightness.
