Traction No matter what you have heard or learnt in the past, this is the most important thing for successful four wheel driving. Without TRACTION, your 4×4 will get nowhere. There are five key elements to traction…. 1. Track condition. 2. Tyres. 3. Suspension travel. 4. Engine revs. 5. The number of driven wheels. Just one of these in poor condition or of the wrong type and your forward motion can be seriously limited.
