4x4 tyres are divided into: Road, All-terrain and off-road. Road tyres ( 80% road, 20% terrain ) are marked by H/T and S/T. In case of those tyres tread patterns are asymmetric. Second type is all-terrain tyres ( 50% road, 50% terrain ). In this case you will see ATR, AT2, A/T or All Terrain. Last type is off-road tyre ( 80% terrain, 20% road ). When reading their description you can see MTR or M/T. Winter tyres for 4x4 cars are not divided this way – every tyre is a road tyre. This wide range of types lets drivers pick according to the type of terrain they will be travelling the most. What differs them from passenger cars are very good handling and grip on terrain such as woods and fields. Solutions used in those tyres give you safety on both: roads and terrain. It is a perfect solution for drivers who want to have same results on all kinds of terrain. Tyres like these have an additional rim protection system which protects the rim from damaging. In this case tyres have inner steel belting which strengthens construction and this makes tread pattern more resistant to deformation. The sidewall is also harder which can lift heavier loads and this feature is very important with SUV cars. These tyres are produced to increase driving comfort as much as possible – this feature is very important in those types of cars. Tyre is silent and lowers all vibrations caused by terrain. Some manufacturers produce their tyres with additional sipes and harder rubber compound which allow summer tyre to act correctly even in winter. 4x4 tyres should also, like other tyres, have a good grip and handling on wet roads. We have to point out that 4x4 CANNOT BE FITTED to non-4x4 cars, because they are built differently and have totally different construction. Fitted to a passenger car those tyres will be much harder and louder.
