A tyre’s adhesion to the road surface depends on what?

You answered correctly. A tyre’s adhesion to the road surface is influenced by several factors. Tyre temperature affects how well a tyre grips the road—warm tyres typically provide better traction. Road conditions matter as well: smooth, dry roads offer more grip, while wet, icy, or dirty roads reduce adhesion. Weather conditions directly impact both the tyre and the road surface—rain, snow, or extreme heat can change how tyres behave. For safe driving, always consider all these factors, as they determine how effectively your vehicle can brake and handle.
