Going to use an '09-'14 F-150 FX4 to build my Raptor clone.. originally the '10 Raptor rolled on 35" All-Terrain T/A KO (315/70R17) tires.. the '09 FX4 comes with P275/65R18 all-terrain OWL tires.. gear wise the Raptor has 4.10's and the FX4 comes with 3.73's.. Can I match the Raptors tires with the 3.73s or is it going to be to much.. don't want to change gears

 

You would get the same RPM at the same speed with 32's. You could run 35's with 3.73's with a Ecoboost or 6.2 - a 5.0 or 5.4 would be doggy at the bottom end.
