Why the hell do they make slicks so much taller than regular street tires. I used to have a set of 26" tall M/T and I would put them on and it was like going from 4:11 to 3:50 gears. What gives? Cant find anything shorter.
I'm not sure, but I'm going to give it a shot. First, I would assume the taller tire allows more sidewall flex to help absorb some of the shock of the initial hit. Second, a taller tire gives you a bigger "footprint" which aids traction on a limited width tire. Thats why all the stock class cars run a 30" tall tire, even though it is limited to 9" of actuall tread.
Just about every tire on a performance vehicle is about 24" tall. This is a guess but I think it is close. The reason I posted the question is that I was looking for a drag radial but the price was going to about 320$ mounted and balanced, for that kind of money I could get real slicks on seperate rims so I start looking and there is nothing out there I could find that wasnt 26+ inches tall.
I have yet to use a drag radial so I cant answer the question about them, although I have friends that use them and they say traction is good, but not like a slick, also tire life is low, about a year if you drag race a lot, another reason to run a dedicated slick.
