whenever i crank the wheel to either the far left or far right and am backing out (havent dont it while going forward) the car wants to barely move.. but if let it out soem, the car will go faster. im thinking they are rubbing on the rear wheel well (closest to the driver) i have 235/60/15s on there and they have never dont this before, but i just noticed it now.. it could be i need to check my alignment againand see if its somethign there (nothing against u camarostud1988.. hell ill prob have u help me) and i dont have the backspacing of the rims off the top of my head, or id post that as well.

Are you sure it's rubbing--you would hear/feel a kinda grinding noise. What you describe is normal for any car that has decent sized tires on it. With the wheels cranked, you create lots of rolling resistance. If you have ever pushed a car inside a shop, you will see the effect. With the wheel cranked it's much, much harder to push.
