Tyre Speed Rating Chart
A tyre speed rating (speed symbol) is an alpha or alphanumeric code that indicates the
maximum speed a tyre can sustain under specified operating conditions. It forms part of the
service description together with the load index. Example: 225/45R17 94V
→ speed symbol V means a maximum of 240 km/h.

Notes
- Speed rating assumes correct inflation, appropriate load (per load index), and proper operating conditions.
- Always follow the vehicle and tyre manufacturer recommendations for size, load index, and speed symbol.

Understanding Tyre Speed Ratings
The speed symbol indicates the tyre’s certified maximum speed. However, safe operation also depends on
load index, inflation pressure, ambient temperature, road surface, and vehicle condition.
For daily driving, choose a speed rating that meets or exceeds the vehicle manufacturer’s specification.
FAQ
Is it OK to use a tyre with a lower speed rating than OEM?
Generally no; using a lower speed rating than specified may not be safe or legal in some regions.
Can I mix tyres with different speed ratings?
Mixing is not recommended. If unavoidable, keep the lower-rated pair on the front only if the vehicle manufacturer permits and drive within limits.
How does load index relate to speed?
Both are part of the service description. Exceeding the load index or running underinflated can reduce the tyre’s effective speed capability.
