Tire Speed Rating Chart
The speed rating tells you the maximum speed a tire is designed to sustain. Find your tire's speed rating letter on the sidewall and look it up below.
| Speed Rating | Max Speed (mph) | Max Speed (km/h) | Typical Use |
|---|---|---|---|
| L | 75 mph | 120 km/h | Off-Road & Light Truck Tires |
| M | 81 mph | 130 km/h | Temporary Spare Tires |
| N | 87 mph | 140 km/h | Temporary Spare Tires |
| P | 93 mph | 150 km/h | Studless & Studdable Winter Tires |
| Q | 99 mph | 160 km/h | Studless & Studdable Winter Tires |
| R | 106 mph | 170 km/h | Heavy Duty Light Truck Tires |
| S | 112 mph | 180 km/h | Family Sedans & Vans |
| T | 118 mph | 190 km/h | Family Sedans & Vans |
| U | 124 mph | 200 km/h | Sedans & Coupes |
| H | 130 mph | 210 km/h | Sport Sedans & Coupes |
| V | 149 mph | 240 km/h | Sports Cars, Sedans & Coupes |
| ZR | 149 mph | 240 km/h | Sports Cars (over 149 mph) |

| Y | 186 mph | 300 km/h | Exotic Sports Cars |
Understanding Speed Ratings
Speed ratings were established by European tire standards organizations. The rating represents the maximum speed at which the tire can carry a load corresponding to its load index. Higher speed ratings generally mean better cornering, braking, and heat dissipation.
FAQ
What is a tire speed rating?
A tire speed rating indicates the maximum speed a tire can safely maintain over time. It is represented by a letter (e.g., H, V, W) found on the tire sidewall after the load index number.
Does speed rating matter for daily driving?
Yes. While you may never drive at the maximum rated speed, higher speed ratings generally indicate better heat dissipation and handling. Never install tires with a lower speed rating than your vehicle manufacturer recommends.
Can I mix speed ratings?
It is not recommended. If you must mix, the lower-rated tires should go on the front axle, and you should never exceed the speed limit of the lowest-rated tire.
