I have a 2006 supercrew fx4 with the 6 in fabtech on it. The dirtlogic coilovers up front have been tweaked to give me an extra inch up front. I was wondering if anyone could give me advice on whether or not I could run a 35x1450 tire on the 20 in rims without any rubbing problems.

 

Depends on your backspacing on the wheels. Your going with aftermarket, correct?

What setup are you looking at? You should be ok with a 35" inch tire, but 14.5 is wide...

 

I've seen one or two trucks running 36x15.50's with a similar setup.
