2003, we converted a 1997 Ford CF8000 commercial truck to our concept of an ExpeditionVehicle.
Swapping from 22.5 to 24.5 on the front axle adds about three inches ground-clearance under the radiator.
For the rough tracks to the remote mountain lakes and isolated Baja beaches we prefer, the additional ground-clearance works for us.
We operate a small organic teaching farm near the outskirts of Eugene Oregon.
Farmers and loggers abound around us, so ground-clearance helps keep equipment earning.
Accordingly, our local heavy-truck suppliers automatically stock 24.5 tires and wheels.
