not exactly true....the more rubber on the road the better, unfortunately with a slick you have no rubber on the road when water gets beneath them.
You have two types of race tires, DOT approved and race only.
Now a DOT tire has to go through a bunch of tests....things like separation, temperature, etc....non-DOT tires are illegal in the US for road use.
race tires don't have to be tested, but some are tested more strictly than street tires are by the DOT.
A drag radial is usually a street-legal and treaded tire of softer compound than normal, many are mostly slick with just a little tread on the outside for water to tunnel out. These are designed to get you to and from the track without a trailer, but not meant for daily use.
A street radial is a normal tire.....some are 'stickier' than others.
A racing slick is a smooth tire of a very soft compound....many times a slick can create enough traction to break driveline components with driver error.
All season tires are tires that can handle snow (many think all-season is for rain, but that is not the case).
