The tires has to be with in 1/4 inch width of the stock size? Interesting. I seem to recall an STI at hawthorn with slicks on in A-stock, and the slicks were definatly wider then stock , probably an inch wider or more. as it was noticeable that instead of completly vertical sidewalls, the sidewalls were recessing back towards the rim, from the edge of the tread. and i think that was the guy who kept thinking Brian D's tires were not legal becuase they were so worn. ah the irony of it all
