What Are Speed Ratings for Tires?

Tires are one of the most important parts of your car. They provide you with traction to help you slow down and stop safely. To get reliable performance, it’s important to take good care of them and make sure you’re following their recommended speed rating.
So, what are speed ratings for tires? World Ford Pensacola explores this important topic to help drivers in Pensacola, Crestview, and Fort Walton Beach take better care of their car’s tires.
What are Speed Ratings for Tires?
Speed ratings are located on the side of your tires. They represent the maximum speed that the tire should travel. For example, if you see the letter Q on your tire, then it means the top speed that the tire can safely travel is 99 MPH.
These ratings usually match up with what the tire is designed for. A spare tire has an N rating because it’s not made to go over 87 MPH. The other extreme is performance tires, which often have a Z rating. These tires are made to hold up at speeds of over 149 MPH, so you’ll usually find them on race cars and roadsters.
Most cars and SUVs on the road today will have a rating somewhere between Q and W. Each one follows a scale that was designed to help you and your local tire center fit your vehicle with the proper tires.

The U.S. Department of Transportation established this scale to get every tire manufacturer and tire center on the same page. By buying the right tires for your vehicle and not exceeding your speed rating, you’ll be in for a safer drive.
Where to Find Your Tires’ Speed Rating
The speed rating should be listed on the side of your tire. Usually, there’s a series of numbers and letters on the sidewall that represent everything from the tire size to the recommended speed and weight. The letter at the very end of this line of letters and numbers, the character furthest to the right, should be the speed rating.
You may also be able to find it on a sticker located on the front driver’s side door jam or the hatch to gas cap. It’s also a good idea to check your owner’s manual since it’ll list all your recommended tire information.
