I want to lower my truck, it's at stock height right now but my wheels are too wide...if I were to lower the truck with the wheels and tires that are on it now, my fenders would rub on my tires. I know I'll need different wheels and tires before I drop the truck if I don't want anything to rub, so I've been looking at some 17"X8" deep wheels and I'm wondering if a +0mm offset would be ok, or if I'd need a higher positive offset? I want to lower the truck 3 inches in the front and 4 in the back.
