I posted this over in the tire/wheel/break forum, and I did not get any responses; I don’t think they are hardcore enough there to run real race tires. Please take a look at the post.

In short, I do a lot of autoXing and soloII style events over the summer and I found these tire which seem to be about $100 cheaper then a set of same sized kumhos from tirerack. Yeah, these tires arnt very wide, but the price seems really good and I have wheels that will fit these perfectly.

I know I can get away with running these at small autoX events, but I'm not sure how they are going to class me at the soloII style events I go to because they are not DOT.

Has anyone else had experience with these?

 

Stock class you can run any kind or size of tire as long as they fit on a rim of the same size as stock with I think a 25% difference in offset.

 

You'd need to be in Prepared or higher to run non-DOT tires.

 

Tires must be DOT in stock class

 

Stock rules say you can run any DOT legal tire but the wheels must be of stock size with the exception of a .25" installed allowance in offset from stock.
