I have the stock 18x7.5 rims on my stock 2005 F150 Ford pickup. The rims came with the Lariat package. I was wondering if I were to buy 17x8 rims, if they would rub or cause damage because of the 1/2 inch extra width. I still have the warranty on it, and don't want to damage the truck with them and void the warranty.

Thanks!!
I wanted to put some 275's or 285s back on there. I forgot to add that in the original question. I'm sorry.
