What do speed ratings mean on a tire? Where can I find the speed rating? Are speed ratings important? All great questions that most people do not know. If you are doing your homework, here is a short video and brief article to help you understand.
The tire speed rating is indicated by a letter on the side wall of a tire. In the example on the video, the speed reading is rated as a W. This W designation means the tire is rated for speeds up to 168 miles per hour. Just because the tire is rated for 168 miles per hour doesn’t mean your vehicle is safe at that speed.
