Factory 20s And 33s

[Duramaxduner]

Hey guys I just wondered if any of you running the factory 20" wheels and big tires had issues with the tires rubbing on the upper control arms? I want to run a 305 55 20 and I have to air down my tires to about 10 psi when I go in the dunes and I just wonder if they would rub since there is no offset? Right now I am running a 275 55 20 and I can get my fingers in between the tires and the upper control arm but I just wonder what you guys have seen running 33s and 35s if that was an issue? I also have the cognito upper control arms.

We have done a few sets of 33&35s on factory 20s.. Never had one rub the control arm, but also haven't aired them down. Which I don't think will change it enough.

Also stock control arms so I don't know how much of a difference that will make.

I ran 305/55/20 BFG AT's on my 11' with no problems. I am now running 275/65/20 Duratrac's and they hit the plastic liner once and a while when fully cranked.
