Speed rating

The speed rating describes the maximum speed at which a given tyre can be safely driven. It is worth choosing a model according to this parameter in such a way that during operation it is not allowed to exceed the speed rating — this creates increased loads on the tyre and can lead to its damage (up to an “explosion”). And it is best to choose an option with a margin of at least 10 – 15 km/h — this will give an additional guarantee in case of emergency situations. For truck tyres, speed indices in the range of 100 – 130 km/h are considered popular, and these are the J speed rating(100 km/h), the K speed rating(110 km/h), the L speed rating(120 km/h) and the speed rating M(130 km/h). For agricultural machinery, the speed is much lower: index A6(30 km/h), index A8(40 km/h), index B(50 km/h), index D(65 km/h), index F(80 km/h) ). There are also high-speed truck tyres and less popular speed indices C(60 km/h), E (70 km/h) and G (90 km/h).
