That is for Street Touring which allow some modifications (ie. basic bolt-ons) done to a car. It says 225 is the maximum tire width.
Please don't lecture me about driving school. I know very well driving school is the best thing for the racing. And by the way, .5 seconds is quite a bit of a difference when you're at national level. And for your comments about my wheels/tires, no I'm not putting extra money for them. I'm going to be spending the extra money on the 17's for the street already, and the 16's will just be sitting here collecting dust that's why I'm going to be using them for autox.
