The two new tires should be installed on the rear axle of the vehicle. New tires generally provide better traction and water evacuation as the tread grooves are deeper. Higher traction over the rear axle of a vehicles is essential to prevent possible oversteer situation and poor vehicle stability.
REPLACE ONE (1) TIRE
If replacing four or two tires is not an option and only one tire can be replaced, make sure the tire is of the same size and construction as the tires already mounted on the vehicle. Make sure to match the single new tire to the tire with the most tread depth, and place both tires on the rear axle.
