Road-gripping ability, also known as TRACTION, is the ability of a vehicle's tires to grip the road and provide stability while driving. It is an important factor in driving safety, as it helps to prevent skidding and slipping on wet or icy roads. TRACTION is affected by the type of tire, the condition of the road surface, and the amount of weight on the tires. Good TRACTION can help a driver maintain control of their vehicle and avoid accidents.
