Well, the contact patch of any tire is very small, once you cut those wide, deep grooves into them, that contact patch shrinks, almost like comparing a thong to briefs and as soon as you do groove a tire the drivers complain all season long how "nervous" the car is under braking, how it "skates" and "skewers" and "slides & slips" towards an apex, it's almost beyond a fan's humble endurance. Slicks have a larger contact patch, yielding more traction under acceleration, better adhesion cornering, braking is more effective. A slick can use a softer compound than a grooved tire because the treads don't shimmy and shake like grooves do, which generates heat and with heat the tires start to throw chunks all over the place so you have to use a stiffer compound with grooved tires. Yes, a slick with a soft compound sheds a lot of rubber, but not in chunks, so when a driver goes off, he can blame "the marbles" ... it's all about the drivers.
I want you to know... I laughed a lot; a comic's best moments aren't nailing a joke with perfect timing, driving an audience to near asphyxiation chuckling as they black out... no , no ...the best thing to watch is another comic bomb, die on stage, but then I have to nod in admiration because you turned a comic's death knell into a routine, a pretty good one; my respects.
