U would have to lower ur max and get used to the messed up speedo. I figure if I get pulled over I will use that for a reason

or just get some fatty 18 in wheels and 225/40ZR18 tires and not have a speedo problem at all.
or purchase some 225/65/15 michelin pilots great tires cost some money though.

Actually, if he gets lower profile (ie, smaller diameter) tires then his speedo and tach will read as if he were actually going faster. So while you think you're blasting down the highway at 80mph, it won't feel like it and you may actually get passed by some Geo Metro or UPS truck because you'd really be doing 60 or 70-something. On the other hand, the car will probably accelerate faster because of the lower effective gearing.
