I for sure use the 75MPH rating of the GY tires when traveling in the 75mph speed limit states.

What's you mileage like traveling 75 with the monster behind you??

One thing about the Goodyear is they always seem to stand behind their trailer tires and pay for any damage incurred within the first 5 years due to tire failure.
The Michelin tire info says it is rated at 62mph while most the other brands in this size tire are rated at 75 mph. That alone is one reason to go with another brand over Michelin.

The 62 MPH is a hold over from 100 KM. Michelin reps have stated that the XTA at lighter loads can be used at high speeds.

Tire ratings are a relationship of speed, inflation and weight carried. Even with 8K axles each tire has 805 pounds of excess capacity. So Michelin states that because the tire is never fully loaded it can exceed the 62 MPH rating. Given the weight of trailers that use such tires, unless one is using a class 7 or 8 truck as a tow vehicle, they should consider around 65 as a max tow speed anyway. Chris

The OP is looking for 17.5" tires so a Maxxis ST8008 or the G614 RST both being a 16" tire won't work.

I frequent more haulers forums than RV forums and I see the Sailun S637 in a 215/75r-17.5" 30.6" dia 16 ply rating @ 4805 lb capacity 125 psi is a very popular tire for those folks that are on the road 24/7 pulling heavy GN trailers.

nuwaowners.org has a very good tire forum for members HH II heavy trailers.

Go with GY "H" tries the only failure I have heard of with a GY "H" is the one Rusty just mentioned. Rusty can confirm or deny but I believe GY paid for a new tire and the damages. I only buy Michelins for my TV's and had excellent performance but for the RV it's GY since they will pay when not a road hazard. I for sure use the 75MPH rating of the GY tires when traveling in the 75mph speed limit states.

Op I would bet your Michelin tire was a recipient of something that punctured the tire.

It sounds like a "fluke" failure. I've seen a few reports of failed Michelins, but one was because of a brake problem that resulted in the wheel getting so hot that it actually melted the Michelin at the bead which deflated it which caused it to disintegrate when the owner kept running it deflated.

I ran the 17.5" Michelin XTAs on our previous Mobile Suites for over 4 years and never had a problem with them. Our current Mobile Suites came with the 17.5" Goodyear G114s and they've been OK so far, but our daughter and son-in-law threw the tread on a Goodyear G114 this year on their Mobile Suites, so nothing is a sure thing, I guess.

Elwood (OP) - which Michelin "model" of tire were you running?

why change? you don,t say why it blowed? could be road junk,, 5yrs no problems , I,d stay with a winner.

For my 34' 5th. wheel trailer, I have used the
Good Year G614 RST "G"rated tires for the last 15 yrs. and have not had one tire problem. I buy new ones every 5 to 6 years regardless of the condition of my old tires. They used to make a Wrangler "D" rated tire that the trailer mfg. put on new trailers to save some profit---They were useless and frequently blew out. Good Year paid to replace all four tires and moved me up to the G614, they even paid for damage to the trailer as a result of tire blow out:):)

Interesting - Just finished reading Trailer Life and their 2015 Reader's Choice Awards did not mention "Tires".
