Do I have to replace my present tires with the same size tires?
Tires should always be replaced with the same size designation or approved options. Never choose a smaller size than those that came with the car. It is recommended that all tires be the same size, construction (radial, non-radial) and speed rating. If tires of different speed ratings are mounted on the vehicle, it is important to place the same size, type and speed ratings on the same axle.Tires of different size designations, constructions, and stages of wear can affect the vehicles handling and stability.
