Tire Speed Ratings

All tires made today are required by law to have a speed associated with them before they can get DOT approval. This number ensures that the tire will withstand highway speeds, and more on certain models designed for pricey exotics.

At a bare minimum, we here at TractionReview.com recommend no lower than “S” rated tires for normal street use. While many folks will never see 112 MPH, it’s always better to have a tire rated for a higher speed than you will ever drive at than to be at the tires limit under normal driving conditions on the highway.
