I do not want to lift the truck just yet. I want to put the biggest tire i can on it without any rubbing problems. I have the factory 20 inch rims and tires which I don't have a problem with. I will run the factory tires in the summer and the new tires in the winter. Any suggestions?

2007 f-150 Supercrew with factory 20 inch tires and wheels right now

 

4x4 or 4x2?

 

It is a 4x4. Thanks, i definately need help on this.

 

if you put a AS on you can fit 33-35s depending on your off set

 

AS claims that you can run a 35" tire with the 2.5" leveling kit as long as it is on the factory rim. Aftermarket rims they do not recommend any larger than 33's.

 

I agree.
