Driving over rock beds in a 4×4
Rock beds are common on mountain routes, dry riverbeds and river crossings. It is important that you know your vehicles clearances and the position of vulnerable components under your vehicle.
- Begin the crossing with your tyres at ‘road’ pressure.
- Deflate your tyres slightly, if necessary. This will improve traction, but you will lose some ground clearance.
- While driving, use the rocks to improve ground clearance.
- Proceed slowly in 1st gear low-range.
- Don’t straddle large rocks. This could result in the vehicle being ‘hung up’ with it’s wheels in the air and stuck.
- Tyre side-walls are easily cut by sharp rocks. A slightly deflated tyre is more puncture resistant.
