One of the most frequent questions we hear is, “Where do I install my two new tires?" and the answer is, “On the rear, on the rear, on the rear!”
Whether you have a front-wheel drive, rear-wheel drive, four-wheel drive or an all-wheel drive car, install your pair of new tires on the rear! The only real exception to this could be a vehicle that has a staggered fitment with different tire sizes on the front and rear.
The reason for the rear installation is new tires on the rear axle will help the driver control their vehicle in wet conditions since the newer, deeper tread tires provide better hydroplaning resistance. With the older, lower tread depth tires on the front, the front tires will tend to lose traction first causing the vehicle to under steer (making the vehicle want to move straight ahead) which can be controlled by releasing the gas pedal to allow the driver to re-gain control of the vehicle!
