as copied from the GGR rules book:
QUOTE Tires: i. Street tires: Any street tire/wheel combination may be used. Tires must be DOT approved. ii. Race Tires: Race tires may be used, but may not be mounted on wheels wider than seven (7) inches or one inch wider than stock, whichever is greater. This leaves open the possibility of cars being competitive on very large street tires. given the choice, what would be better and more cost effective?? wide street tire/wheel or 7" wide rim with race tire are there DOT tires "close" to being a race tire??? |

As usual others have more clearly expressed than I am able..
but mike I just wanted to comment regarding your mention of the rain channel.. dot certification involves quite a bit more than a rain channel... There is a federal testing process with load/time/heat etc.... Certification is a pain in the butt, and I don't imagine its cheap either... Sorta like crash certification for cars... a lot of low volume manufactors don't want to/can't afford to go through it... The full race slicks haven't been through it... doesn't mean they will blow up or kill you ... they may or may not pass the test.. but the differences are more than a rain groove.. There are a few tire that fall into this inbetween.. for example the hoosier rain tire. Its compound is more similar to a dot tire than a slick.. its composition and side wall is also more similar to a dot than a slick.. yet hoosier didn't bother to put it through certification probably for cost reasons.. I've heard that it was actually faster than the 03 hoosiers, but didn't qualify as a dot for pca stuff, so it gets classified as a race tire even though it is truly not built like a slick... true slicks are another world. very different in every way.. most will heat cycle out before they wear out. Go with the DOT... use something cheapish to learn on. My experience with 2nd tear level tires has shown that the victoracer works better with a 2000lb car where as the yoko is superior with a 3000lb car..... just buy one of these consistent and longer lifed tires, and then do the driver training route. b |
