So, I searched for my answer, but could only find the answer for 18" wheels.

I have a 2013 Screw 4wd, and my rough country 6" lift kit will be here today. Will the stock 20" wheels and tires on my truck work without any issues until my new wheels and tires arrive, or should I just wait until they are here too.

I'm sure it's been answered somewhere, but I cant seem to find it.

 

So since nobody else knows, yes, the oem wheels and tires will work.

Seen multiple times on the rough country website that they won't, but I just installed mine today and had no problem getting the wheels on.
