A detailed explanation of tyre specifications
The markings on a tyre may look confusing but they are actually very important. Each marking provides a vital piece of information about the specification of each tyre. This includes information such as the maximum speed the tyre can safely sustain, the loads it can carry and the relevant safety standards.
If you are looking for a guide with the tyre markings explained in Australia, the following will be of great help. From enabling you to understand the tyres speed rating codes to the tyre date code, the tire writing and lettering provide you with a lot of information.
- The width of tyre in mm.
- Aspect Ratio of the tyre. The height of the tyre sidewall as a percentage of the width. In this case it would be XX% of XXmm.
