I have an 03 1500 4x4 with a leveling kit and 365/65s on 18s (35x13.00) terra grappler all terrains. i have never rubbed during regular driving, towing, off roading, anything. i do not know the backspacing on the wheels, but i couldnt be happier with how they look. the tires fit in the wheel wells perfect, and do not stick out past the body of the truck too much, overall perfect fit for me. i do not have the lower valance on the front bumper though, so if you were to do it you might have to either trim or take that off. i kind of like the way it looks without it though...

 

i meant 325/65***

 

'02-'05s can run the 35's with as little as a level kit, but many '06+ owners are reporting problems, especially around the control arms. If you are going to just go the level kit route, then stay with 33's. You'll also be able to get by on stock 3.92 gears with the 33's, you'd get better performance with 4.10's, but the 3.92's won't really hurt you, so this will save you considerably.If you have 3.55 gears stock, then a gear change would be in order not matter which way you went on the lift and tires.
