In prep for departure I crawled under the back of the coach to check the spare and find out what size socket I needed to carry. (3/4”). I fully expected to find a full service Hankook matching the 6 on the chassis. Nay Nay
What I found is an off the wall sub-brand “Cordovan” tire. I did some research and discovered that it comes from TBCBrands, a Florida Outfit. However, they do not list it as one of theirs, offer zero warranty information and no references.
I have not found specs yet so I can determine if it the same diameter as the Hankooks.
under my rv. Six Michelin on the rv. Never thought about possible difference in diameter. The size is the same 225-75-16. Looks like 29 inches diameter.
Thanks for the research. It looks like the Cordovan has a 40,000 mi warranty. A bit short but I have seen worse. If it is because of increased traction, that could be a good thing. They are cheap enough. Few ratings to be had. The ones I could find are 3 star across the board. That does not speak well for the Cordovan.
I also found that the Hankook is 29.2” just like the Michelin. As you can see in Fords specs, the Hankook does 709 Revs per mile at 45 mph (growth factor).
Cannot find that spec for the Cordovan.
Edit: There appears to be a discrepancy in literature on the Cordovan diameter.
They will do anything to save a buck.. where you aren't looking and sometimes where you are. I noticed the cheap spare a few months back. Most of us will never use it, so I guess it is ok.

Either they are saving a buck or after 4-8 buyers the Dealer has new tires for resale! Or someone in the shop has a side business reselling the Top Brand Tires!
I purchased my rv used and it had an older well worn tire. I purchased a new tire and now I have a spare that matches my tires and one that I can trust.
I just took a look at my own pic in the original post. In the middle pic you can see the edge of the rim clearly. I just noticed the weights. Holy cow! Thats a lot of lead. Made me relegate that tire to permanent spare duty.
