I haven't been on in a while and am wondering if I can fit my 305/55-20 Pro-comp Extreme AT's on a stock OEM 20" aluminum wheel without rubbing. Right now they are on 20x9 Panther chrome Realm wheels (not sure of the backspacing) and they fit fine, but the aftermarket chrome can't take the winters in WNY.
Does anyone know of a good place to get "take off" stock wheels. I'm looking at either the 2010 FX painted cast aluminum 6 spokes, or the regular cast aluminum wheels. Thanks for the help.

 

The problem with the OEM 20x8.5 inch wheels is they have 6.5 inches of backspacing. This pulls the tire inward and can cause some 305mm (12.50 inch) wide tires to touch the upper control arm/ball joint. This is usually a problem with tires with aggressive sidewalls. So, the answer is: maybe. Hopefully someone here is running the Pro Comps and can tell you for sure.

 

Thanks for the reply. I thought I might hear from you, you've helped me in the past with some questions, I appreciate it. There was a truck on here that had the stock 20x8.5 aluminum wheels that he had painted grey, and he had the same size Pro Comp AT's mounted on them. I'll see if I can track him down on here. Is the back spacing the same on the older (07-08) OEM 20's as on the newer style (09-10's)?

 

Yes.
