Tyre Speed Rating: Why it is important?

Speed Rating of a tyre

The speed rating of a tyre represents the maximum speed the tyre can reach. When your old tyres are worn off and you need to go for a new set of tyres, then you should always follow the instructions given in the user manual of the manufacturer. The speed rating is generally mentioned on the sidewalls of a tyre and is denoted alphabetically. For example, if your tyre has got ‘S’ rating then it is capable of reaching a maximum speed of 180 km/h. In the same way, if it has got ‘H’ rating then it can go up to 210 km/h. However, while choosing the best tyres for your car, you should always keep in mind that the tyres should complement the vehicle’s performance.

It is also recommended that the speed rating of your tyres should be more than the top speed of your car. Note that speed ratings just apply to tyres that have not been harmed, altered, under-inflated or overloaded. Furthermore, most tyre producers keep up that a tyre that has been cut or punctured no more holds the tyre maker’s original speed rating, even in the wake of being repaired.This is in light of the fact that the tyre manufacturer can’t control the quality of the repair.
