You could.... but you would have no rim protection, and they wouldnt look right.
With a 9" wheel you need 275's. Wont your tire shop let you trade them?
Well I ordered some 17x8 rims from ford racing and some black lug nuts now my last concern is if my tires are going to be damaged at all when they take them off and switch them out on the non-warped rims. Supposively the rims I'm riding on right now are pretty bad according to the tire shop that wants to fix my 3 rims for $600.
...and if they tell you otherwise, take them someplace else. I find it a little shady that they didn't inform you that new rims could be bought for less than the price they wanted to fix the old ones.
