Question: what is the difference between w and v rated tyres?
Answer: This means that a tire with a V-rating, for example, can be driven at 149 miles per hour until it wears out! Less frequently seen ratings are Q 99 mph and R 106 mph- used in some light truck tires. The W rating replaced what was once Z, which was anything above 149 at the time, and is now limited to 168 mph.
