Which of the following factors has the greatest impact on the grip of the truck tyre to the ground?
Explanation
Correct answer: The type and condition of the road surface.
The type and condition of the road surface has the greatest effect on the grip of a truck tyre. A surface that is wet, icy, or covered with mud or gravel sharply reduces the friction between the tyre and the road. Neither the size of the tyre nor the engine power affects grip as much as the condition of the surface the vehicle travels on.
