Tire Speed Rating
Quick facts on tire quickness.
Speed rating is a handy system to indicate the range of speeds your tire is certified to safely handle under specific service conditions. This rating is indicated by a letter, A-Z, tacked onto the end of the tire's service description, as seen here:
|205 = Section Width in Millimeters|
|60 = Aspect Ratio|
|R = Radial Construction|
|15 = Rim Diameter in Inches|
|91 = Load Index||(Service
V = Speed Symbol
Check out this chart to see the top speeds that correspond with each letter.
When tires have a maximum speed capability above 149 mph (240 km/h), a "ZR" may appear in the service description and if it can handle over 186 mph (300 km/h), it must. Here is an example:
||270 km/h (168 mph)|
||300 km/h (186 mph)|
