Crack in sidewall of rear outside dually
So I head to my RV storage place today on my day off to do a few things and get ready for a trip next week. I decided to check my tire pressure and found a 2-3 inch long crack in the sidewall of a re...

Do you have a spare tire? It is probably a different tire outside diameter than the current tires. Just a slight difference.
What I did when I had a right inside blowout is put on the spare, continue to my sister's house, and then rotate the spare and outside good tire to the front, then put the front on the back (they are basically the same age and would be same tire diameter.) I replaced the bad tire and one of the front one's (kept it for a friend) and found some 14 ply replacements! (they do not make them anymore).
So if your rear tire has a lot of miles on it, then I would consider putting on the front pair in the back (if the rim size and tires are the same).
If you have older tires on the front, and the rear is the same size, it will not matter to have the old and new tires on the front, with slightly different tire outside diameters (say within 3/4" outside diameter will not matter on the front).
On the back, say one tire where 30" tall and the other 29-3/4" tall. The outside diameter is 3.145X the height, or about 3/4" longer on the 1/4" taller tire. So while the inside tire might turn 600 times per mile, the outside would only turn 595. This is a problem! They are attached to the same axle, and will turn the exact same RPM, but one will be dragging the other along due to being taller.
You could have them mount the new tire, and then using a cloth tape measure, (for sewing) you can measure the outside diameter easy, and make a decision to replace both tires, and perhaps keep the best and youngest as a spare? Or if you have a 'new' spare, it will be the same diameter as any new replacement tire.
Good luck!
