Tire Speed Rating Selector
Key Takeaways
- Never downgrade speed rating. Match or exceed the rating on your vehicle placard and original tires.
- Use a buffer for style. Daily = 0% buffer, occasional high-speed = ~10%, motorsport/track = ~20%.
- Ratings measure heat resistance. They are not a target speed—do not exceed the tire’s rating.
- Winter & specialty tires differ. Some winter tires carry lower speed ratings—follow manufacturer limits.
- Pressure and load matter. Maintain proper inflation and correct load index to preserve speed capability.

Fitment Notes
- OE floor: If your placard says H, V, W, Y, etc., do not install a lower letter.
- Track use: Consider motorsport-rated tires and consult us about heat cycling and pressures.
- Winter sets: It’s common for winter tires to have a lower rating; verify maker guidance and keep speeds down.
- Mixing: Avoid mixing different speed ratings on the same axle.
