What is AZ tyre?
Z-rated high-performance tyres are rated for speeds in excess of 149mph. Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph. See the full list below. However, H-rated and higher-speed tires vary by manufacturer and brand. For example, when you repair a sidewall on an H, V, or Z-rated tire, you should no longer use the tire at extreme speeds. Similarly, if you repair a hole smaller than 1/4-inch in the tread, the original speed rating may no longer apply.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.
What is an AZ rated tire good for?
Speed rating Z While it nearly always means a high performance tire for high-performing sports cars, “Z” may actually appear in the middle of a tire’s size information. When it does, it represents either a maximum speed of more than 149 mph (240 kph) or 186 mph (300 kph). The ‘Z’ indicates that the tyre can safely operate at speeds higher than 150 mph. This is in addition to its normal speed rating (see below). Your tyre will not have this ‘Z’ if it’s rated for a speed lower than 150 mph.
