UK speed ratings explained
The speed rating is the maximum speed at which a tyre can carry its rated load. The most common UK speed ratings are:
- T — 190 km/h (118 mph) — common on older family cars
- H — 210 km/h (130 mph) — common on family cars and SUVs
- V — 240 km/h (149 mph) — common on UK family and premium cars
- W — 270 km/h (168 mph) — common on premium and performance cars
- Y — 300 km/h (186 mph) — performance and premium
Replacement tyres should meet or exceed the original speed rating. A lower speed rating may invalidate insurance and reduce safety.

What does the speed rating mean?
The speed rating is the maximum speed a tyre is rated for under its load. Common UK ratings are H (210 km/h), V (240 km/h), W (270 km/h) and Y (300 km/h).
What does the load index mean?
The load index maps to a maximum weight each tyre can carry. Replacement tyres must meet or exceed the original load index.
Where do I find my tyre size?
On your tyre sidewall, the driver's door frame sticker, your fuel flap or your vehicle handbook.
What if my tyre size doesn't match the standard format?
Some tyres use slightly different formats, including ZR speed prefixes or fractional rim sizes. Enter what you can read — we'll flag anything that looks unusual.
