i put 1.25" adapters with 245/70's. It brought the tires out flush with the fenders. I have had them on for about a month. No alignment problems I can speak of. Bending over the pinch weld on the rear fender well is a must.

Hey there kjsportcrd06....Welcome to lost and head on down to the Southern lost section sometime if you get the chance. There are a couple of us that live in Cordova and another in Bartlett. So whenever you get a chance give a shout.
