Well, I borrowed a tilt/flatbed trailer to haul a car from California to Nashville Tennessee and bring one back. Prior to leaving I did quite a bit of "road ready-ing" on the trailer. I thought about replacing all tires as they were Chinese Load Range E tires that were about 3-4 years old. Against my better judgement I aired them all up to 75psig, put two spares in the pickup and took off with the Yukon on the rig. Changed the first on 120 miles down the road. The tire place said the other three were in good shape and did not recommend changing them. By Kingman AZ the second one shredded. Swap a spare on to it. An hour later the third one shredded. In Flagstaff I put 4 new 225/75R-15 Goodyear Endurance tires on @ 80psig in each. Smooth sailing the all the way to Nashville and all the way home. I suppose if I took off with two spare tires expecting the worst.............I should have known I needed to replace the tires! I will be replacing the Goodyear Marathons on my CreekSide with these Endurance Tires

We now have over ten thousand miles on our Endurance tires -- so far, so good. These are Load Range D on a very small trailer, and I do not go over 62 mph. So yes, this is overkill. But I never again want to experience a blowout on a single axle trailer. Once is enough.

My research into these is that they are made here in the USA and are the replacement brand for the Marathon. They sound pretty skookum to me and will be ordering them for the trailer.

Hi.. I put on Goodyear endurance tire2 on my 5th wheel this spring.. I have about 4000 miles on them now and I like them at this point. Jim A.

The set four I had installed in Flagstaff took me to Nashville and back to California @ 75mph for just about 5000 miles. Smooth sailing!

Mine have close to 5000 miles this year also. No issues.First year is easy. Year 4 to 6+ are the tough ones.

I've been towing trailers of one kind or another for 42 years and have never ever experienced a blow out. I've had two flats. One on a small utility trailer that got a nail in it. The other was last summer on my 5ver driving east on I40 just east of the Arizona/New Mexico state line. This was caused by a bad valve stem. Fortunately my TPMS warned me of the leak. At one time or another I've put on the cheapest ST tires I could find because the pocket book just wouldn't stand anything else, I've used U.S. made Marathons and now Maxxis. The key, regardless of tire, is proper tire pressure and loading. You mess up either one of those and you are doomed no matter what brand you buy.

Again, if you're referring to "test stds.", you need to provide a citation. But, they're simply adhering to industry standards.- from the TRA.

one difference is that the goodyear endurance does NOT need any inflation adjustment or carrying capacity reduction above 65mph. the load rating is the same as other sized ST tires and applies all the way up to 87 mph.

Does this make the endurance any better than other ST tires? who knows. but at least the endurance has sidewall markings indicating a higher speed rating than other ST tires. Only time will tell about the quality of the tire.

But I'll bet in the next year or so we will find more ST tires going through the additional testing to be able to stamp a higher than 65mph speed rating on the tire.

NHTSA has a pdf of the testing required for tires. some 80 pages of test requirements including the testing for speed rating etc. etc.

Gee sound guy, I’ve read two of your posts on this topic and each has been rather harsh. Remember it’s not what you say but how you say it. People post on here to get other people’s experiences and opinions on topics not to be ridiculed. In fact I just read your posts on tire inflation and again you can’t post a comment without being sarcastic to the other posters. Thanks for your experience and opinion but yours I don’t need.

Makes me laugh when I hear people say "it's the best towing tire I have yet". I have been towing trailers for most of my adult life and I can never tell the difference between one tire brand or another on a trailer on how it feels going down the road.

Laugh all you want, who cares? :R I myself switched to a set of Endurance after one of my originally supplied off shore tires self destructed by splitting internally and I immediately noticed much improved towing with the new tires. This past summer I camped with a friend who co-incidentally had also installed a set of Endurance tires on his own trailer just prior to this trip. When I happened to mention I'd just installed a new set of tires he replied "Me too!" and went on to describe just how much more stable his trailer towed with the Endurance tires, all without me saying anything at all about it. Doubting Thomases will only be convinced once they try a set themselves, until then their opinion is meaningless. :R

I was in my local Good Year dealer last week having a set of LT tires installed on my newest horse trailer. Talking to the owner of the store, and the subject of the Endurance tire came up. At the end of the short conversation, his comment was, "it's still just an ST tire".

From that comment, I take it that he too is withholding judgement until more time has passed and the tires have a history.
Maybe they will work out well. I'm like a few others here though, I have found what works for me, so I see no need to do beta testing for the tire companies.

yes it sorta still is an ST tire. However it is N (87mph) speed rated without derating the load capacity. Many other ST tire mfg do indicate going above 65mph is possible if you derate the load.

So.... in theory goodyear has at least designed the tire to pass the much more stringent speed rating tests than the pretty easy to pass ST 65mph test.

Now I have no intention of towing my trailer at anything close to 87 mph. But it is good to know the tires in theory are designed to handle the load at that high a speed.

We've put about 1500 miles on our goodyear endurance. The previous Maxxis went about 20K before needing to be replaced, no failures.

Also, the endurance took way smaller weights to balance than the Maxxis did. And the Maxxis took less weight than the Towmax that they replaced.

Time will tell, but it looks to me like Goodyear is trying to address some or all of the issues with ST tires.
I am not certain that an ST tire with a higher speed rating has to pass any of the govt. mandated performance specs. Just having the ST designation may exempt it from those requirements.

It may be that the only testing that will be done is in house testing by goodyear.

Don't laugh. OSHA has been doing this sort of thing for years.

We have an outside contractor bring in propane floor cleaning equipment at my work. Often they belch a lot of smoke/noise and awful smells.
I filed an OSHA complaint once. OSHA announced in advance to the company when they would be doing their inspection (as a courtesy I was told)
On the agreed upon date a brand new buffer showed up with all the latest noise reduction and smog equipment. It was so quiet and smell free that you could stand by it and hardly tell it was running. After they passed the inspection, that buffer disappeared and old smokey came back. After some more conversations with OSHA, I found that it is a rigged system. The contractor company is required for their machines to pass annual tests.... But they are permitted to self test.

Guess how often they fail.

since the sidewall is stamped with a load index and a speed rating it's highly likely they must test to and pass the industry std test for speed rating and load index.

Now for the mfg that don't stamp the tire but have a link on the website talking about increasing speed rating by derating the load, that I would agree is highly suspect that it would meet the test stds. If it did why wouldn't they stamp the tire?
