To be considered a "street tire" by SCCA standards means a UTQG treadwear rating of 140 or higher. To qualify for Street classes - as opposed to street TIRE classes, they must be DOT stamped. Nationally there are no street tire adjustments. There are street tire classes - the IRL goes to STX - and that's it. Other Street classes allow DOT stamped tires, period, including "R-comps" with treadwear ratings in the 30-80 range.

Those V700's are a very good autocross tire. They have a UTQG treadwear rating of 50. They are a treaded R-comp as opposed to a semi-slick, but an R-comp they are. Nationally, this means they're right for Stock, SM, or SP. They most likely will NOT qualify for any local "street tire" modifiers, which usually have a PAX adjustment - or even separate run group - for cars in those classes running tires with 140+ treadwear ratings.

Great info!! What tires would you recommend that are legal in a street tire class?

If you're going to run in STX, I would recommend a few street tires. But that limits your mods. If you're in Stock, Sm, or SP and will have a second set of tires for race only, I wouldn't recommend a street tire - get the real deal, run in the regular class. Take-offs are cheaper than good street tires anyway.

bigbrother, in all honesty, how do the nankangs handle as compared to other street tires in the sub-$500 range?
