4x4 tyres are divided into on-road, all-terrain and off-road. On-road tyres (80% road, 20% terrain) are marked as 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 markings. Last type is off-road tyre (80% terrain, 20% road). When reading their description you can see such markings as MTR or M/T. Winter tyres for 4x4 cars are not divided this way – every winter 4x4 tyre is an on-road tyre. This wide range of types lets drivers choose according to the type of terrain they will be travelling the most. What differs them from passenger cars is very good handling and grip on rough 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 protector which protects the wheel from damage. In this case tyres have inner steel belting which strengthens the carcass construction and makes the tread pattern more resistant to deformation. The sidewall is also harder in order to carry heavier loads and this feature is very important with SUV cars. These tyres are produced to increase the user’s driving comfort as much as possible – this feature is very important in 4x4 vehicles. The tyre has to be silent and lower all vibrations caused by terrain. Some manufacturers produce their tyres with additional sipes and harder rubber compound which allow summer tyres to act correctly even in winter. 4x4 tyres should also, like other tyres, have good grip and handling on wet surfaces. 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, these tyres will be much harder and louder.
