I need some help with picking the right wheels and tires. I thought about going with factory rally wheels but I kinda want to go 20’s with a 4/6 drop.

Yes the wheels on it are 20’s right now but they are flaking real bad and I’m not sure if I like them.

The 17" aftermarket ralleys look good, with and without a drop. Use around a 275/50 rear tire and a 245/50 or 255/50 front tire.

Thanks. I really do like the rallies.

On a Suburban, which I assume shares the same basics up front. A standard dia tire scrubs the top of the inner fender when the suspension is near bottoming out. I changed mine to a 3" drop up front with smaller tires to make it a 4" drop.

It got to the point I would cringe when I would hit a big bump waiting on the scrubbing sound that always came.

I run a 5" front drop with 245/50/17's or 255/45/17's depending on my mood over the years. The 245/50's will hit the inner fender on really huge bumps, but they are so few and far between I don't even think about it. The 255/45's never hit.
For your truck I'd go 18"s. If I could get my current rims in 18"s I would probably switch.
