Will 35's fit on an 07 silverado without rubbing? Or 33's? I would like to
put them on 20X10's if possible?

 

You MIGHT be able to get them on with a level kit and lots of trimming...Other wise look at 4-6" lift kits...

 

i have a 6" procomp lift kit and it rubs with 35's. very minor but does rub. Procomp and every tire shop i went to said to run 33's. I dont mind a little rub!
i just switched from 20x10 to 20x12.

 

my roomate is stuffin 37's on his prerunner 07 silverado. but it has a custom long travel kit.

his 35s rubbed on turns, (35/12.5-17) but not till the very end of the steering radius. BUT he was on a total chaos mid travel suspension kit. basically a 5" lift in the front and 2" in the rear is what his suspension translates into. He also has fiberglass front fenders and tube bumper. These pics are his old setup, il get some of it on the 37s soon.

 

I just put a rough country 6 inch on mine and i had to trip just a very little bit to clear 35's
