Are the formula one racecars tires smooth or flat?

Answer 1

It Depends. The smoothness or the general characteristics of the tires change based on their type.

a. Slicks - These are the tyres used during dry races. They are smooth and have little or no grooves in them

b. Intermediates - These are tyres that are used during light rain or drizzles. They have small grooves in them to provide better grip under the light rainy conditions

c. Rain tyres or Wets - These tyres are heavily grooved to provide good grip to the cars which are being driven under heavy rain conditions.
