I am looking at buying new rims for my 2009 F-150 Crew Cab, the ones that I found and like have a -12mm offset and have a warning that it may not fit wheelwell. This comes from a national warehouse and after talking with a tech, they could not confirm it would fit or not because of the offset. I am wondering if there are any sizing tolerances that would let me know if they would fit, or to keep looking for something else.

 

We need some more info. 4x4 or 4x2 truck? Tire size you want to run? Are you lifted, lowered or stock? What is the width of the wheels?
