Tire speed rating chart
What is the tire speed rating?
The speed rating is a letter on the tire sidewall for the maximum permitted speed. W means 270 km/h. The chart below lists all common symbols in km/h and mph; ZR means over 240 km/h.
Try a speed symbol
Type the letter after the load index, such as V in 91V.
- km/h maximum
- 240
- mph maximum
- 149
Reference-table value only. Always match your vehicle placard and tire sidewall markings.
Compare load and speed markings
Compare a current and candidate single service description, such as 91V and 94W.
The candidate table values meet or exceed both current values.
| Current marking | Candidate marking | |
|---|---|---|
| Maximum table load | 91V: 615 kg | 94W: 670 kg |
| Speed symbol limit | 240 km/h | 270 km/h |
Reference-table screen only. Match the vehicle placard and manufacturer requirements; higher table values alone do not approve a tire.
| Symbol | km/h | mph |
|---|---|---|
| L | 120 | 75 |
| M | 130 | 81 |
| N | 140 | 87 |
| P | 150 | 93 |
| Q | 160 | 99 |
| R | 170 | 106 |

UN Regulation No. 30 supports the symbol-to-km/h values shown here. A speed symbol describes tested tire capability under specified conditions; it is not permission or a recommended road speed.
