What does a tire speed rating mean?
The speed symbol is the letter after the load index, such as H in 98H. It states the top speed the tire was rated for in a standard test. T is 190 km/h (118 mph), H is 210 km/h (130 mph), V is 240 km/h (149 mph), W is 270 km/h (168 mph) and Y is 300 km/h (186 mph). Letters in brackets, (W) and (Y), mean a tire rated above that speed, and Z means above 240 km/h. Miles per hour are the km/h figure x 0.621371, rounded, so a few published charts differ by 1 mph for P and Q.
| Symbol | km/h | mph |
|---|---|---|
| B | 50 | 31 |
| C | 60 | 37 |
| D | 65 | 40 |
| E | 70 | 43 |
| F | 80 | 50 |
| G | 90 | 56 |
| J | 100 | 62 |
| K | 110 | 68 |
| L | 120 | 75 |
| M | 130 | 81 |
| N | 140 | 87 |
| P | 150 | 93 |
| Q | 160 | 99 |
| R | 170 | 106 |
| S | 180 | 112 |
| T | 190 | 118 |
| U | 200 | 124 |
| H | 210 | 130 |
| V | 240 | 149 |
| Z | over 240 | over 149 |
| W | 270 | 168 |
| (W) | over 270 | over 168 |
| Y | 300 | 186 |
| (Y) | over 300 | over 186 |
The letters are not in alphabetical order of speed (H sits between U and V), so read the table rather than assuming. Replace a tire with one rated at or above the original equipment speed symbol to keep the vehicle maker's intended performance.
Frequently asked questions
What does H mean on a tire?
H is the speed symbol for 210 km/h, which is about 130 mph.
Is a V rating faster than an H rating?
Yes. V is 240 km/h (149 mph) and H is 210 km/h (130 mph). The letters are not in alphabetical order of speed.
Does the speed rating mean the tire is safe at that speed?
It is a laboratory test rating, not a recommendation. Load, pressure, tire age and condition all matter, and legal limits apply.
Can I use a lower speed rating than the original?
Vehicle makers specify a minimum. Using a lower rating than the placard or owner's manual calls for is not advised, so ask a tire professional before you do.
