Why do you need special tyres for a 4×4 vehicle?
It is important to install special tyres for your 4×4 to maintain contact with the road and stay safe when driving. Due to their heavy weight, 4×4 vehicles have a higher centre of gravity which requires further assistance from tyres.
Standard 4×4 tyres, which typically refer to off-road tyres, have a deeper tread than common tyres and contain larger gaps. This allows the wheel to maintain contact with the ground through increased traction, even in adverse weather conditions. This contrasts with standard tyres which, when encountering difficult terrain, will quickly become bogged down in the mud and become uncooperative with the ground.
The most important reason why 4x4s require special tyres is that they are powered differently. Power travels from the engine and eventually resides in the transfer box, where it travels to a differential unit. The consequence of this is that all wheels are working. Unlike standard cars, no wheel passively spins as, instead, they all work together to manoeuvre the vehicle. This allows for better movement on difficult terrain where 4x4s are usually employed.
