I have a 2000 F250 7.3L with OEM tire size (265/75/R16) and spent months trying to figure out how to increase the tire size without dropping thousands of dollars on a lift. I took the truck into Les Schwab - they were _awesome_ by the way - and they added a leaf upfront for ~$500 and installed new 315/75/R16s on new 16x8.5 wheels with a -12 offset . Here's the results:
Also got tired of the undermount spare tire lift. It's possible these tires don't fit but even if they do, I wanted a swing out hitch carrier so we went with the Rig'd Ultraswing Megafit. Really happy with the build quality and a 1/3rd of the cost of a new bumper with a swing out tire carrier.
- Front tires rub a little on the leaf all the way at full lock. Not a big deal to me.
- The truck handles better if you can believe that. It feels more solid, less wandering.
- Zero loss of power. This engine does not give a shit what you do to the truck. It just keeps rolling.
