What Is a Tire Speed Rating?

What Is a Tire Speed RatingTire speed ratings indicate the maximum speed a tire can safely handle before it no longer performs as desired. The higher the speed rating of your tires, the more control you can enjoy at higher traveling speeds. Your tires are giving a certified speed rating in the form of a letter from A to Z with speeds ranging from 3 MPH to above 186 MPH. With the exception of H-rating, the higher in the alphabet the rating, the better a tire can manage heat and friction created at higher speeds.

It is important to note that your actual speed capacity may be lesser than the designated tire speed rating. This rating indicates the maximum speed for a new tire, and your actual maximum capacity depends on tire condition, pressure, cargo capacity, and road conditions. Always pay attention to weather conditions and adhere to speed limits to ensure you and your car stay protected.
