I can not get the Michelin xse 275 h rated tires here in Canada anymore. Is anyone running the 295 tires on the rear single axle with no issues such as rubbing etc?
I run them front and back.......no issues.
Peter, 295 75R 22.5 tires are with on one tenth of an inch in diameter of 275 80R 22.5. Both have run fine in my coaches.
If you want the Michelin brand tires, Call Dave Ward, 32 one 6 zero 7 2265. He is a Michelin reseller and has found tires when dealers say there are none. He is in Florida and will share how being in Canada impacts his sourcing tires.
I'm running 295/75R22.5 Toyo on 36' 98 U270 with no interference issues. Many others are as well.
To make comparisons valid, please specify:
275/80R22.5
vs
295/75R22.5
OR vs
295/80R22.5
Just saying 295 doesn't really address the issue.
295/75R22.5 are within one revolution per mile compared to a 275/80R22.5. The 295 is about.0.79 inches wider. All things equal, the wider tire will stop shorter and handle better. Probably not a factor but the 295 is a lower profile tire so in case of a blowout, there is less distance between the aluminum wheel and the road. 295/75-R22.5 vs 275/80-R22.5 Tire Comparison - Tire Size Calculator | Tacoma...

If you decide on a 295, regional or bus/OTR use (most RV manufactures recommend regional), load rating and speed rating are specifications to consider.
We have 295s on our 1993 U300. Love them.

Running the 295/75R22.5 size on our rig with no problems
Pierce,
I think they are so close to the same size that it makes no measurable difference.
295 x .75 = 221.5 mm between the rim and the road
275 x .80 - 220 mm
1.5 mm difference x 2 would make the 295/75 about 3mm larger in diameter than the 275/80
Yes, the numbers are in the site I linked to: 295/75-R22.5 vs 275/80-R22.5 Tire Comparison - Tire Size Calculator | Tacoma... (https://www.tacomaworld.com/tirecalc?tires=295-75r22.5-275-80r22.5) As you say, not much difference and one manufacture to another may be as great as this. We occasionally get a very slight contact with the right bag in off road slow turns on uneven ground but nothing significant.

X2 👍👍 they are a little wider
295/75/22.5 came on my coach and when it's time to buy I will get the same.
OK, one suggestion-- applies to all coaches, but is especially important when fitting a wider tire (even a little wider):
Check and adjust CUT-ANGLES. Very easy to do. Special tools needed: Small standard screwdriver and something to measure a small gap-- I use an old scrap of 1/8" thick aluminum about 6" long. Also a wrench to adjust the physical/mechanical stop.
Why did I say applies to all coaches-- easy. All of us want the max cut angle without allowing the tires or wheels to contact body or suspension components and more critically, so that the Sheppard steering box does not "keep working" against a mechanical stop, as this shoots hydraulic pressure way up and is often the cause of blown seals in the steering box.
This takes two people-- one to turn the steering wheel and another to check clearances and make adjustments. The adjustments are done on the two tiny exterior screws on the Sheppard box-- one on top, one on the bottom where it is easier to see. Each limits cut angle in one direction. Screwing them in reduces cut angle, out increases it.
Coach needs to be at standard ride height (a good time to check) and reasonably level. Running the front wheels up on 2 stacked 2X12"s should give you safety clearance. If you are "thicker" use three! Easier for the helper to turn the steering wheel with the engine running/power steering.
When set up correctly, the Sheppard box (with properly adjusted screws) will not allow the tires/wheels to contact body, chassis or suspension components AND also for there to be an air gap between the mechanical stop (the bolt) on the steering knuckle.
Have the helper turn the wheel all the way to the lock on one side. Verify both clearance for tire/wheel and about 1/8" on the mechanical stop. If there is too much gap/reduced cut angle, screw out one of the adjusting screws on the Sheppard box. Easy to verify whether top or bottom screw is the one to use for that side-- just screw it in or out 2 full turns and see if it affected the side you are working on. Return to initial screw location. On our coach I gained 7 degrees on one side and a whopping 10 degrees on the other. Since this was the OE steering box and had never been adjusted after it left the factory, it meant it was not dialed in at the factory. Appreciated those extra few degrees each time I had to maneuver.
This IS CRITICAL anytime you change tire width or the steering box is removed for any reason. Do not count on whoever works on the box to return the cut angle screws to exactly their original position OR assume this was dialed in at the factory.
