Michelin 275/80R 22.5 XZA3 LRH
« on: September 09, 2011, 08:00:58 PM »
 This tire was OEM ON MY 10 tour. I want to carry a spare tire...no wheel. Called some of the larger tire dealers Boston area...no one has this in stock..searching their wholesalers for me now. I have been told michelin does not make this tire now. Is their a comparable replacement tire???

When I couldn't find them in my original XZA2 I replaced with CONTINENTAL HSL 275/80R22.5 LRH.   I've had two of them for about 4 years, and the other four for almost 2 years.  Both times I found them at a Best One Tire dealer. They ride and handle well  ...and they were apx $100 less per tire than the XZA2's would have been.

When we put new shoes on the Horizon a couple of years ago, we went with XZA3s, sorry to hear they aren't available any longer.

I carried a spare tire on the roof of the Jeep to and from Alaska; I was so happy to get rid of it at the first opportunity in the lower 48.  Even on the Alaska Highway, road service is available.  My spare tire now resides in my wallet  ;)

Did they drop just the LRH or both the G & H version?  An H load range is a lot of weight for a 275/80 tire and most chassis manufacturers have probably gone to 295 or 305 for that much carrying capacity.

Nothing wrong with Continentals, though. I've got Conti 11R22.5's on my rear axle now. That's equivalent to a 295/80 in most all respects.

I have the 295/80 across the rear axel on mine and wish I had the 11Rs,, much cheaper and more available thruout the country, although they are slightly smaller in rolling diameter.>>>Dan

The Continental 11R22.5 is only 1 Rev/mile skinnier than a GY G670295/80. The difference is almost unmeasurable. Carrying capacity is a little less, though.

I'm surprised that they are telling you that the 275/80R-22.5 LRH is not being made, I just bought (6) in March.  Our dealer had none in stock & got all of them in a week.  The date codes showed that they were only a month old.  The salesman is more likely saying that they are waiting for Michelin to make another production run.  This is a common tire used for RVs, buses, & OTR trucks.

Are you aware that the bare tire weighs 120#?  I'd rethink the need to carry that size & weight around as a spare.

Michelin is weird about 22.5" tires...their 275/80R22.5 is a 295/75R22.5 to most of the industry.  Those are the same size, they will work on the same dual without a problem.

That is dangerous advice.  They may fit on the same rims, but they aren't at all equivalent tires.   The 295 has about 700 lbs more carrying capacity per tire than the 275, which means you could have axle overload if you changed from 295 to 275.  And the 295 gives 503 revs/mile vs 518 for the 275. That will give you a 2.5% difference in speed and odometer readings. The 295 is a wider tire and requires more dual spacing.

The 275 is a smaller tire in all respects, so don't go swapping your 295s for 275s without calculating all the effects of the differences. Michelin sells the 295/80 size as well as the 275/80, so clearly they know about the difference.

This is not adfvice.  This is not a theory.  I drove a truck (2005 Ford F-650) with one 295/75R22.5 and one 275/80R22.5 on each dual.  The truck had (left to right) one Bridgestone R194, one Michelin XZE, one Goodyear G149, one Michelin Pilot XDHT.  In over 70,000 miles, there were no, repeat NO problems and minimal wear.  Side by side, the tires were identical...same height, same width.  A guy from Oliver even confirmed they use the same caps!

LOL, we have 255/80R22.5 XRV all around, rated at 5205 lb/110psi front; 4805/110psi rear.  I don't even know if the larger tires would fit even though they are rated for more weight.

...with one 295/75R22.5 and one 275/80R22.5 on each dual... Side by side, the tires were identical...same height, same width.

Ah, I see you are talking about a 295/75 rather than the 295/80 typically used on large RVs. I missed that in the original post.  The difference in aspect ratio (profile), with the 295 being a 75 profile while the 275 is an 80 profile, makes for a difference in height.

This has nothing to do with Michelin  vs the rest of the industry and has everything to do with arithmetic. 275 x 0.80 = 220 and 295 x 0.75 = 221.25, so indeed the sidewall heights will be nearly identical. There is still a difference in load capacity, but on a standard 20,000 lb dual axle each tire need carry only about 5000 lbs anyway, so that's not an issue.  If it was on a front axle, the story might be different.

But the width is still different. 295 is still 20 mm wider than a 275.  However, by combining a 275 and 295 on one wheel, the required dual spacing is reduced vs what a pair of 295's would need. Using a pair of 275's would reduce it even further.

No, the width is NOT different.  Side by side, they are the same size.  Again, they are capped in the same mold!

Clearly the section (tread) width is different between those two - 275 vs 295 or 20 mm (0.8"). The overall width (widest part of the tire) is probably much closer. For the 275/80, it varies between 10.9" and 11.1", depending on which model Michelin you are looking at.

Oddly enough, I can't find the 295/75 in the Michelin data book, but I know they make one cause I see it for sale. Competing brand 295/75's mostly spec out at 11.2" overall, which is very close to the 275/80.

But this is mostly just trivia. The real issue is weight carrying capacity. You either have enough, or you have a blow-out.

They generally do not...never seen a 295/75R22.5 Michelin.  A few other companies (seen BFG and Continental) have a 275/80R22.5, but not many.
