it won't mess any thing up as long as you have good clearance. you can buy tires to fit the rims as well as match up the ride height you are currently at. you wanna change the rim size but not the height. is that right?
Thanks for your input about the tires&wheels.I talked with another guy about this,and he told me just get the original tire to put back on it because it's possible that it might mess with the transmission and the rear end sence it's all computerized.If you think this would happen please reply back.Thanks Ed
