I use Nokia 15in auto tires on all of my car trailers. The "trailer" tires are crap.

Hopefully they're not 15" Goodyear Marathons... the Airstream forums are resplendent with stories about them... and major failures... This is the reason so many are going to 16"... But I understand the 6 to 7 year rule is a standard as MoHo tires rarely earn the 50K+mile wear on 'em. Most time sitting & a'waitin' for some action in the sun before giving up the ghost...

We also went through several years of tire problems while running the Goodyear Marathons on our 29' travel trailer. Decided to switch to Cooper brand of trailer tires and never had an issue with them. These all were 15" 6 ply rated tires....

Putting Toyo M170 on my SOB, 295/75R-22.5.
M177 tire has what they call an "isolation groove" around the perimeter and the M170 does not.
Dealer says this groove is easily damaged by curbs taking a chunk out and he often gets folks coming back claiming a defective tire.
He strongly recommended to use the M170 almost identical tire to the 177 to avoid this one issue.
Will see how they work out, travel safe.
Regards,

I am thinking of replacing 4.5 year old Michelins (have a buyer) with Toyos and wonder what is the difference between Toyo M170 and Toyo M177 tires?

Wyatt, I have had my issues (well documented) with Michelin, but I am curious about why you are getting rid of tires that are less than five years old.

Even if you don't care about yourself or your own coach, think of the guy you run off the road when you lose control, or the guy behind you who gets that "gator" in the windshield, or the motorcyclist that doesn't see it, and hits it, and dumps his bike. THIS, I can testify to.

This is the best argument I've seen for replacing old tires. I've seen too many incidents on freeways during my career.

Bridgestone, continental, Michelin say 10 years for legal reasons.

Dry air or nitrogen prevents cord belt rusting as does not using a water based grease when mounting and ozone protection and checking for cracking can make that a safe length of ownership.

No way I am telling you a safety protocol you feel is correct should not be done..

The earlier changeout time cannot be wrong. Just expensive

Regarding inflation pressures: In Oregon we have a lot of unmanned weigh stations that make it is easy to weigh each axle and side on my 97 U295. I've Toyo 154's H rated, however anyone with Toyo tires should find this chart useful. I'm running 115 in the front (approx correct for 12,000 lb front axle rating and current load) and 95 rear (min. recommended 19,000 lb axle) https://toyo-arhxo0vh6d1oh9i0c.stackpathdns.com/media/2155/2017_commercial_loadandinflation_tables.pdf

I also posted the following on a different reply "It is not just the sidewall checking or cracking, the rubber dries out. It then separates, the flapping will heat up the tire, raising the pressure, and then, boom, if not just throwing off the tread. Three years ago I had a blowout, never want to again or hear of someone else. The day before the blowout I went to install 6 new tires on the rv I just bought, they were out of stock, driving approx. 100 miles to get the tires installed. The day before, checked tire pressure, jacked up the rv and had the tire store check the tread, 3/4 left, no tire checking, no splits in tread. The next day, boom. You are not wasting $$ to replace at 6-7 years. You might be wasting your life if you do not. Michelin in the past recommend dismounting and inspecting at 5 years, replacing at 10. I now will not go over 7 yrs. I've know several people that sell their tires at 3 years and buy new ones. I believe that is overkill. All 3 had experienced a blowout. If I had the $$ I'd do the same."

Now it's my turn, again. Much sooner than expected.

I've had it with Michelin.

Three years ago, I replaced all six tires with brand new (fresh date code) Michelins. Great ride and handling, zero tread wear.

But now they are checking. Badly. After just three years in Southern California.

I need to replace my tires, pronto. Anything but Michelin this time.

So I am re-reading all the tire threads on the forum, and will try and find a suitable tire with as good ride and handling as possible, probably not as good as Michelin, but safety is more important to me. My mechanic says he wouldn't feel safe driving my three year old Michelins very far at all.

Will likely go with Toyo, but will also look into other brands.

My mechanic says Michelin is the only brand in this size. What is the equivalent size to use from Toyo or other brands?

Michelin makes Uniroyal truck tires in 275 80R 22.5 also.

The diameter of the Michelin tire is the same as a Toyo 295 75R 22.5. The Toyo tire is 20 mm wider.

Hope this helps.

Have had Continental HSL2 Eco Plus 275/80 LRH steer/all position tires for two years. Pleased with the noise and ride.

Bob, We've had the same Continental tires on for six years with no troubles. Had a chunk come off the outer rib and was told that it was no problem. No checking, etc. Curious how steel belts rust. Aren't they enclosed in rubber on the inside of the tire, too? If they can rust from moisture on the inside wouldn't the moisture on the outside do the same thing. Maybe I'm the only one who drives in the rain or through puddles.

I put on eight Generals tires this year, I believe General is a division of Continental. I think the ride is great but have only had them on a short time so far. They gave me $ 600.00 for the old Michelins.

Yokohama seems to be popular with truckers, and manufactured in the USA, at a new plant in Mississippi.

When I get the coach back from my mechanic, I'll run it to a Michelin dealer to see if the 7 year warranty helps with my 3 old tires. Wish me luck. Mechanic says the cracks are troublesome, who knows what Michelin might say.

Had Toyos on my BMW 730 for many years and found them much better than the Michelins. I put them on coach 3 yrs ago and they look fine and ride well 170.s

What was on the coach before Toyo, how do they compare in ride, handling, steering?

Why did you choose 170 vs 177 Toyo Tires?

What size? Any issues with odometer or rubbing?

Answer: 7 year old Continental/General/S371. New Toyo 170 is much more smooth all around. Maybe because they are new.

Why did you choose 170 vs 177 Toyo Tires?
Answer: Not for any strong reasons but 177 has a edge that visually appear to me as if it could wear out faster or problematic according to something i had read somewhere during my research.

What size? Any issues with odometer or rubbing?
Answer: 295/75R/22.5, No rubbing. I did not pay attention to odometer, I have a feeling it is within ~1 mil. I think OEM was Michelin 275/80/22.5

We had MOT replace the Michelins on our coach (chalking at 5-6 years old) with Toyos M154, 295/75R22.5 16 ply (H), steer all around. Put about 6K on them so far and have no complaints - handle very well, comfortable drive. Actually feel better ("tighter" steering) than the Michelins at the same pressure (105lbs front, 100lbs rear). Tires, mounted & balanced all around was about $2800. Quite a bit less than with same in Michelin.

I get my coach back today or tomorrow, so will soon see what Michelin has to say about the cracks. If that is not enough, my other mechanic says my Michelin tires on the MDX, also three years old, are badly cracking. He too is checking with Michelin to see what they might do under warranty.

As i said earlier, unless i get a good in-warranty deal from Michelin, I've had it with them. My RV mechanic is recommending Honkook.

The seven year/700k mile warranty on my Xza-3+'s is that they guarantee the inner casing will take three retreads though an authorized Michelin commercial retreader for up to 700k miles or seven years.
