Eli5: Why are f1 tires smooth and grippy, but street tires with no tread are dangerous and slippery

2.79K viewsEngineeringOther

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

Smooth tires means maximum contact with the road surface, hence their use in F1. That would be the same for your vehicle.

The difference is that your vehicle spends a lot of its time on roads that are in less than ideal conditions. The main problem the average driver faces on ordinary roads isn’t getting maximum traction (grip) during cornering — it’s coping with conditions that could separate the tire from the road and cause a loss of control, like driving through wet conditions — or worse, slush, or snow.

In those less-than-ideal but normal driving conditions, you need the grooves and treads on the tire in order to disperse the water.
