When you Google why are f1 tires smooth, the answer is no tread means more surface area, so better grip, but when you Google why do street tires have grooves, the same answer comes up. I’m confused. Also, is this a physics question, engineering or technology? Lol
In: Engineering
F1 tries are extremely soft so they can mold themselves to the surface to keep flat. They also deteriorate extremely quickly.
Commercial tires typically are at a higher pressure and designed to last longer, so don’t mold themselves as much. If they were completely smooth as well, they would have no grip if there was a rapid change of surface. The grooves are there to increase the surface area in loose surfaces such as dirt or water.
