JV-Tuga asked:

“Have those hundreds of pickup drivers adjusted for the offset odometer reading of the distance travelled?”


Big Dave answers:

Yes. Reprogramming the speedometer on Ford (I mostly talk to Ford guys) pickups is easy. There is a tone ring in the rear axle and all you have to do is tell the computer what size tires you have. Some guys (computer geeks) do it themselves, for others like me its $75 at the dealer. If they have not reprogrammed the speedometer, I ignore them.


JV-Tuga asked:

“Also, outside of stop and go traffic, wouldn't those larger flywheels be beneficial, like on the highway?”


Big Dave answers:

If all you did was drive the Interstates, that might be true, but nobody drives like that. Even light hot-shotters and driveaways drive enough surface streets to destroy any advantage the large diameter tires give them in MPG. These subsets do tend to use larger diameter tires to gain load capacity.
