you CAN'T steer, you can't accelerate, and you can't brake
not to mention the wheel has to be VERY heavy to be strong enough to take the forces because it's so large. Those clear wheels weigh something like THREE HUNDRED POUNDS APEICE. It's simple STUPID...
A truck lifted to clear 44" tires is fine if he actually uses it, as it's street legal, not to mention they don't weight NEARLY as much...
Personally, the ONLY reason to go with a larger wheel is to clear bigger brakes, as you're moving the weight mass out and it decreases performance in all regards (turning, stopping, acceleration)
it's NOT a performance mod, it's a "my dick is small so I'm going to over compensate"
