RV Tire Recommendation

Recommended Posts

I'm looking for a recommendation for replacement RV tires. I currently have 6 Toyo M147, 11R22.5, 146/143L tires mounted on my 2004 Alpine Coach. Although the tires are in good shape and ride great, they're now 8 years old and starting to show some uneven wear on the front tire edges and a slight bit of early weather checking on one of the dually sidewalls. I have always maintained the correct pressures and alignment. I checked with Toyo and they say that my current tires are no longer available and they do not manufacture tires specifically for RVs. They referred me to a local truck tire center. I checked online with the FMCA Tire Program and came up with a list of over 30 different 11R22.5 tires manufactured by General, Continental and Michelin with prices ranging from $367 to $652 per tire. I've seen tires for under $300 online. I'd appreciate a sanity check before I shell out over $3 grand on tires.

djcarlson1,

Welcome to the FMCA Forum.

A question before we get started-- is 11R22.5 the OE size on your coach (per the GVWR sticker which is likely in the nose next to the diesel fill)?

Welcome to the FMCA Forum. I know how you feel. I am going through the same process. I am looking at The Continental program.

It would also be good to know what the load range is, probably G or H

Goodyear is the only tire company that makes a true rv tire these days. I have a set of Hancook on my coach. I've had real good performance from them.

Add to that the Michelin XRV series.

I just compared prices on 275/70 R22.5 Michelin XZE2 & XZA2(didn't find XRV) and Continental Coach HA3 via the FMCA web site. The specifications are very close and load weights are identical. The Continentals were $50 less per tire at $489.32 + tax.

So, I am considering Continental, but do not know anything about them as related to RV tires.

Sometimes there are marketing decisions that dictate who sells or advertises certain products to different markets. For a variety of reasons some companies would rather not be confronted with the problems of improper maintenance (low inflation & overload) seen on too many RVs. Some are making the conscious decision to go after the "niche" market of RV application.

IMO many "truck" tire would work satisfactorily in RV application. Some tire companies do identify generic types of service as more applicable to different designs.

For RV service it is generally suggested "all position"   and "delivery" or "regional haul" or similar service. While "Bus" may seem similar to RV it really isn't as many Bus tires are speed limited and have extra tread depth (increased cost) for in city service.

I am going to try the Continental HSL2 Eco Plus 275/80R22.5 load range G Price is $401.00 +FET. This should be close enough to the 255/80R22.5 that came on it that Continental does not offer. I have used several tire comparison programs and the difference is minimal.

My main problem is geting the tire store trained up so they understand how to use the program. The outher is is finding inventory.  I have one store that has the tires but can't seem to figure out the program and one that has used the program but can't get the tires.:o

There is a tire company in Denton that handles the Michelin tires. You might check with the. Can't remember the name but is out on Hwy 380 east and the loop. They might be the ones to call.

Bill,

A 265/75R22.5 is a lot closer in dimensions to the 255/80R22.5 than is the 275/80R22.5. 

You might also look at a 275/70R22.5, but will sure has to check clearances to body and suspension components, as well as verify proper off-set and rim width.

Herman, I have a local Michelin guy I have bought from before. The problem is the Continentals are about $100.00 cheaper than the Michelin advantage price.:o

Brett, Yes but Continental doesn't offer a tire in that size. I have tried several tire comparison programs and find this one pretty good. https://tiresize.com/comparison/

The 275/80 is only 1.2" larger diameter than the 255/80 and .8" wider I don't think there is a problem.

I have plenty of clearance and they list to fit on my rims.

Big difference is revolutions per mile.  Per the Michelin documentation:

255/80R22.5 is 538 revolutions per mile

275/80R22.5 is 516 revolutions per mile

That significantly changes your effective axle ratio, speedometer, etc

These are going to be steer tires. It would be 1.9 mph faster at 60 mph. The rear tires are 10R 22.5 they came on the couch. :P My speed already runs at 5.8% faster than what it shows. I have a corrected GPS speedometer that I use.

I plan to install Sailun truck tires on our MH when DW is able to travel again. If you wish to check up on them this is your size.

Sailun is a popular tire in Canada, and is becoming known in the U.S.A. now. I notice many HDT's at truck stops running them.

I replaced my 5er tires with sailun load range G tires and eliminated my tires worries, never had another tire failure.

Think I'll stay away from China this year! :)  Sailun is distributed by the GBC Group in W. Palm Beach, FL who is part of the SCOTA Group of Tokyo, Japan. :P

My only recommendation for whatever tires you buy are that they are as "new as possible". There's a lot of tires sold as "new", BUT have a manufacturing date that is already a year old... check the sidewalls the date is stamped into every tire.  

Tires last on average 5 to 6 years.  It's much more likely that you will run out of time before the tread is run down. On a vehicle as large as an RV and due to its height and center of gravity, it's much safer to replace the tires in terms of time rather than actual wear. Just my opinion.

The size comparison web page is interesting but IMO it is not a substitute for printed (or web page) dimensions from the tire manufacturer. Tire "size" is a generic goal and all tires have some variation. Sometimes the variation in one dimension can be significant for one tire design because it might have been designed in Europe to meet a different application. I am aware of some tires being "tweeked" to fit a specific application.

I also note that a critical dimension "Minimum Dual spacing" is not provided by the web page.

It might be ok to use the page for a quick check but I would NOT rely on it for final, actual dimensions.

Yes Minimum Dual Spacing is a factor However as I am talking steer tires it would be irrelevant. I would bet that if you pulled 10 tires out of stock (same size) there would be more than 0.8 difference between some of those rires. I have compared 3 of the different comparator programs and found them to match the factory listed dimensions quite closely. 

However it would be a best practise to always check the manufactuers web site.

The tire company in Denton, TX is Pro Tire.  Just bought 6 Toyo tires from them and they are great.  Pat is the owner.

Welcome to the forum. Now go put some miles on them.;)

Never heard of Sallun tires "up here in Canada". I have always bought Michelin tires with great results. How much would you pay as you had a tire failure or blowout? Don't go cheep with your tires - your and your family's life might depend upon it.

That's odd; http://www.sailuntires.ca/MRT/dealer-locator.html

I figure if they meet the Canada trucking industry requirements, they're good enough for me. Sailun tires meet the exact same govt standards as Michelin. I've read of many Michelin tire failures, plus the sidewall cracking flaw.

Interesting, just looked at link.  There are a lot of excellent tires available out there, that your not paying for the name and advertising....when I had 19.5" tires on Gasser coaches, I ran Kelly's!  Had no more problems than any of the other, big brand names and very cost effective!  How their performance compare to air ride and 22.5', I don't know, but guessing that it would be a harder ride, as they are mostly OTR truck tires!

Carl,

I am using a Goodyear OTR tire front steer and the ride is the same as when it had the original Goodyears RV rated tires  on it as supplied by Safari. I do not think it is the least bit harsh. The ride did improve when I put the nice gold Konis on it however.
