The speed rating system was developed to help control the safe performance of tires at standardized speeds. As a general rule, tires with higher speed ratings also handle better at slower speeds. Department of Transportation (DOT) set the ratings scale, shown below. But tire makers test their own tires and assign their own speed ratings. Wider, larger-diameter tyres often have a higher speed rating as they are usually fitted to higher-performance cars therefore, are typically designed to cope with higher speeds.

It describes the top speed for which a tire is certified. Once the highest speed rating a tire could have, “V” used to represent a maximum of 1mph ( 2kph ) or more. Nowadays, it means 1mph but no higher.

A relatively new addition to the speed rating chart, tires with speed rating “W” can achieve a maximum sustained speed of 1mph ( 2kph ). A tyre ’s speed rating is the top speed it can maintain under its approved load capacity. For example, a tyre with a speed rating of ‘Y’ has a top speed of 1mph. Your tyre ’s speed rating can be found in the tyre ’s sidewall data and is always referenced in the form of a letter, usually after the wheel diameter.

Going back to our Audi, the H speed rating is equal to 1miles per hour , meaning that under optimal conditions, the tire can perform at speeds up to 1mph. Speed rating ensures a vehicle’s tires match its top speed capability. Now just a secon leadfoot … that doesn’t mean you should drive 1mph.
