Automobile manufacturers choose tires that have the best safety, performance, and comfort for their vehicles. Vehicle manufacturers may approve alternate tire sizes for certain vehicles in which the original handling characteristics can still be maintained. However, it is important to be aware that tire sizes inconsistent with those listed on the vehicle information placard can adversely affect vehicle safety and stability. A change in the outside diameter of a tire can affect the accuracy of your speedometer, your odometer and possibly the safe operation of your vehicle. Always check with the vehicle manufacturer before changing tire sizes.

A recent trend for some motorists is to upsize their wheels/tires. For example, installing a bigger diameter wheel/tire. It is important to note that installing a larger diameter wheel on your vehicle can sometimes be accomplished by replacing your original equipment tires with a lower profile size equivalent. The overall diameter of the replacement tire must be equivalent to the recommended original equipment tires. A tire specialist is equipped to provide you with sizing options.
