While tire size does not dictate the specific characteristics each tire has, it is something that cannot be neglected when searching for your next tire set. Each tire size consists of numbers and letters that have specific meanings. The different components of the tire size together determine on which vehicles and in what type of applications these tires can be used. Learn more about what each section of the tire size means.
