Ok...how about *Shaved* BFG Radial T/As?

Like what?

nitto 555r perhaps.

I assume your looking at 14 or 15" wheel diameter tires? if so then the side wall of the tire will have more flex then any tread ever did. even if you had the BFG tire shaved or any sort of modification to make it a better tire it will still handle like a shopping cart. if you want performance handling in a tire then your going to have to step up to the 17" or better rim diameter. thats why all the new cars have them. they are better in every measurable way.
