We'll definately have to trim the front and rear of the flares but the backspace on the rim should be enough to allow the tires to tuck. It will probably touch the flare if the tire is turned though, If that is the case I'll either relocate the flare or just take them off. I like the look of flareless anyway.
Thats because they're a 10.5 on a 15-7 rim. They are a very skinny tire but do pretty well offroad. They've been on both mine and my dads rigs. We had them on a 15-8 rim with 4" backspace so they didn't look as skinny.
