Hi all, I just inherited at truck of my dads. It's 2005 45000 miles 4.8 and lower 4/6. He never did put any aftermarket wheels and I'm wanting too. My question to you guys what's the wides wheel/tire comb for the rear and normal size for the along with the B.S, you guys are running. I'm thinking of 8" up front and a 10" on the rear. Let me hear you guys thought. Thanks
