Looking at a couple different Super C's on the F600. Both Dynamax and Grand Design use three different size rims. Rear inner is steel, outer is aluminum and front is aluminum.Some say they just carry a spare tire (no rim) and have a tire service put it on whichever rim has the bad tire. I hate waiting (and paying) and would prefer to do it myself.I do have the Bead Buster and I have used it with my impact to remove a couple large tractor tires so I should be able to swap the tire out myself on the side of the road.The other option (from a post on the Dynamax forum): This guy says to just get a spare to fit the front. The buy some through hole lug nuts. That way you can use the tire in any position.Thoughts on this idea?If we carry a full spare (tire and rim) will carry it either in the cargo trailer with the Xpedition or if pulling a TOAD in the back of it.

Per Grand Design: "They are all the same tires, but different wheel configurations to accommodate offset and backspacing"

Correct what?They run different spec rims (not talking aluminum vs steel in each of the 3 positions, that’s common and doesn’t affect the spare) ? if so what is it? Are the fronts converted to SRW?what about the rear? The chassis is standard and same offset inner/outer is how any/all dual wheel vehicles come off the assembly line. I’d be real interested to hear their “custom” setup because it defies logic. Also defies standard roadside tire changes. Which isn’t the case unless one is running staggered setup wheels or srw conversion on the front of a dually. (of course the latter makes having the same size tire in all 3 positions virtually impossible)Gotta know the problem before finding the solution.

Where’s the laughing emoji? Still waiting for you to fill us in on these “differences” since you’re the one who thinks you have an issue. It’s crazy how someone can be smart enough to make enough money to buy a RV that costs more than the median home price in some states yet can’t be bothered to respond with anymore than “learn to read?”My point was, IF what you’re saying is actually true and you could produce what the different offsets were (since the lug pattern, wheel diameter and likely the wheel width is the same if it takes the same tire), I could tell you which spec wheel of the three “different” ones would work as a spare in all positions. Instead, you’re asking a question based on some weird thing you quoted and can’t be bothered with the details.

I know, but he/she refuses to acknowledge that. At this point it’s just spam and could be some _______ living in his moms basement dreaming of Super Cs while eating Cheetos playing video games….

OMG, this is classic gold plated humor!!!What on earth are you talking about? Not the home prices thing. Everyone knows that and doesn’t care. Im talking the “new” tire rotation “routine”? What’s new? What changed? I mean, I’m not that old but tire rotations and the reasons and positions to rotate to have not changed one bit. Even though most, including tire shops, don’t understand proper rotation based on what’s happening to the tires. But even more boisterous humor is why tf you’d need a trie machine to rotate tires? The only instance or conditions I can think this is even remotely applicable is when one is wearing the outer half of tires prematurely by driving on predominantly curvy highways. In that instance when we lived in CO mtns, I’d usually have the tires removed and flipped once the outside tread got to about 50% to use the other half of the tread on the outside. And that is done once per tire and not really common. Most just wear them down and replace when the outside is bad and the inside is still 50% or more. And yet even funnier, your post/rant/story has nothing to do with the (also inane) topic!

Just dropping by to see if JDF and khiggins have provided anything of substance…..lol.
Would seem someone who is claiming to be a farmer and can apparently dismount and mount a med duty truck tire on the side of the road would be able to understand a little more and have more informative responses than “learn to read.”

Real headache doesn't even come close to describing the new routine for tire rotation. I'm 64 and hate to pay the inflated prices for such things. We're building a new 40x80 shop here on the place for personal use and I'm already shopping for the tire machine and spin balancer. Prices of new construction in this area have gone thru the roof and clear out of sight, so we're putting the new house plans on hold, building the shop and a concrete pad for parking our 5th wheel on when we're home. I rotate tires religiously just about, so paying to have it done on the new F-350 Platinum won't hurt near as bad when I can do it myself here at home. The old Coates style just won't cut it this time. It's gotta have the bead breaker, the power lift/lower and rim clamp design. I'll find the ones with my "name" on them eventually.

  And a little credit where it’s due, to this guy, IF he’s talking a dually then it’s more likely to do one tire flip rotation on the front tires like I mentioned about the mountain road driving, but only the fronts because heavy duallys running pizza cutters up front will a lot of times exhibit some of the same outer tread wear prematurely on the front tires under “normal” use.
  Rear tires on a drw? Meh. If they’re getting feathered a bunch maybe swap them L to R once or twice during the tire life.
  But removing tires from rims (even on a dually) especially on a srw is an effort in idiocy in most cases save for the cases I mentioned.

I guess I’d ask the mfg/dealer of these $3-400k rigs some very specific questions.

Well my apologies….never seen a normal ish dually truck with 3 different backspacings.
And honestly still find it hard to believe.
But assuming it’s true, and say the inner rears have the least backspacing or offset, no reason that offset wouldn’t work on outer rear or front.
What are the different dimensions?
Did you visually see this looking at these rigs?

There’s 3 different size rims/wheels? I doubt it.
what makes you think a standard steel rim like your inner rear dials won’t work in other positions?
Maybe these new dually trucks are special?
