John tells me that Ford has stated explicitly that if the speedometer/odometer function modified from stock in any way--this includes changing tire size--it voids the warranty, by definition. Do not pas Go. Definitely do not collect $200.
Moral of the story: All of John's conversions utilize the original go-cart wheels and tires. And--at least according to him--that is the only option there is. Perhaps someone else will figure out how to hack the system without causing Ford to declare it a warranty-voiding change.
In any event, I think I'll stick with my ten year old F-350.
