With the 2" As leveling kit can i fit 35's? And if so how bad is the rubing would 33's be better?

 

If your truck is 4x4 then you will be able to fit 35's on the stock wheels or wheels with very similar specs. The 33's probably won't rub but the 35's will, depending on the tire it's not too bad.

I have the 2" Skyjacker kit and my truck sit 1/4" higher in the rear.

 

Right. A 35x12.50 will rub the control arms slightly at full steering lock.

 

I think im going with the 2" As on my oem 18" wheels with 35x12.50 bfg mt km2's

 

I Have a 2.5" spacer and have 33" BFGs and they do not rub at all
