All-terrain tyre
（重定向自All terrain tire）
An all-terrain tyre is a type of automotive tyre most commonly found on four-wheel-drive vehicles.
The all-terrain tyre is intended to provide a good compromise between off-road capability and on-road manners. Since manufacturers are aware that the majority of sport utility vehicles (SUVs) and other four-wheel-drive vehicles will never stray very far from public roads, the tyres they are fitted with as standard tend to be biased towards road use. That is to say that for highway driving in a variety of conditions, they will offer good traction and low noise levels.
