17.Most lifted trucks use 15-inch wheels with tall sidewall tire combos. That's a fine look, but we wanted less side wall so our truck would have better cornering abilities. We selected a set of Weld Racing 18x8.5 Evo Velociti 6s for both front and rear. Here, the rim is trial-fit for size and clearance. Our offset was perfect for what we had in mind. If we didn't want to run the fender flares and widen the stance of our truck, we would have ordered rims with an inch more backspacing.
