Tire Speed Rating Decoder
The letter in 205/55 R16 91V is the speed rating. Select a letter to see the certified maximum speed and what it means for your driving.
How it works
The speed rating certifies the highest speed the tire can sustain. It must meet or exceed the vehicle's top speed capability. Most passenger tires are rated S to Y; H is common for sporty cars, V/W/Y for performance models.
Frequently asked questions
Can I use a higher speed rating?
Yes, a higher rating is always safe and often comes with a firmer ride. Never go below the rating the manufacturer fitted from the factory.
Does a higher rating mean better grip?
Not necessarily — it certifies speed capability, not wet grip. Wet braking is rated separately by the EU tire label.
