# 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.

Speed symbol

### 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.

Current marking Candidate marking

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.

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.

Seasonal check

## Planning a long summer drive?

Use the budget and running-cost tools before a trip, especially if the current tires are worn or the replacement size changes diameter.

What changed

- Added a localized current-versus-candidate service-description comparison using the published load-index and speed-symbol tables.
- Verified the published speed-symbol table against UN Regulation No. 30 and added visible provenance.
