Goodyear made Marathon tires in it's Ohio plant for years. They came in every size that typical ST tires were sold. Then, in the late 80's, Goodyear shut down that line and moved it to China. The early 90's Marathons started having significant problems and in 1994 Goodyear had a recall to exchange all existing 14" and 15" Marathon tires with "upgraded" tires. That tire also had significant problems and Goodyear has still got a lot of "followers" who refuse to buy Marathon tires.

Last year Goodyear introduced the Endurance as the "evolution away from its Marathon brand" It's been on the market almost 9 months now. I can completely understand the rejection and reluctance that comes from experience with the old Marathon line.

Anyone who didn't know about the Marathon history or who never had them destroy the side of their trailer may think an "American manufactured ST tire from Goodyear" is a "great tire".... Those of us who sat in Las Vegas or Phoenix with the side torn off our Holiday Rambler when our Marathon ST tires exploded may not feel quite as "warm and fuzzy" with Goodyear's claims of improved tires.... They told us that when they recalled and replaced our defective tires with tires that were no darned better than what we originally had.

Time will tell, but I won't be their "test bed". I'll stick with Carlisle or Maxxis until there's enough history with the new Goodyear line to document that it's not a "Marathon with a different tread design"....... Goodyear burned me once with bad ST tires, they won't get another opportunity to use me to test their "new stuff".

No offence Alley Cat but your original post stated that your 2 blowouts were with Goodyear Marathons. If I misunderstood my bad. My point in the original post is that every effort to improve your position for safety will also improve the quality of you trip. Less stress when you reach your destination is always a good thing and with every trip we make, our new experiences make each trip a little better than the last. Of course I will take you Endurance tires off your hands, bring them on over.

My comments are to counter that my Endurance Tires are responsible for the best camping experience I had which is merely an ad for that tire. We can all agree to disagree and still be civil don't take offense.
I think you are mixing apples and watermelons. The OP asked about a 27 foot travel trailer, not a 22,000 lb 5'er. I am not even sure Goodyear makes a Marathon or Endurance properly rated for that beast. They do make them for the OP's trailer.

I will leave the technical portion of your brake statement to the experts, but I don't know of a single 5-8k trailer that comes with discs from the manufacturer. It would be nice, though.

So I am new to the tire discussion but from everything I read on this forum I am going to shed my Trailer Kings in the spring. I have only towed 35 miles from the dealer to home. I thought I would go with the Endurance because of some good comments about them. I am now having second thoughts.

I have a double axle utility trailer that have 10 ply NANCO tires on it. Have hauled all kinds of things, some very heavy loads of green firewood. They have given me good service and a stable ride over the years.

I think I will look into the NANCO's. On first glance the ST225/75R15 looks to have a J rating. Here is a link.

The "J" rating on the tires in your link is NOT a "load/ply" rating which we normally see as G-14 ply, F- 12 ply, E-10 ply, D-8 ply, C-6 ply. A load range J tire is a 18 ply tire with a PSI recommendation of 127 PSI, probably much heavier than you'd ever want to put on a travel trailer of any size or weight. The "J" has no bearing on the ply rating or the load rating, but is a "designator" to identify the loading range not the ply ratings, just as the speed rating letters, L, M, Q, Z all represent different speed ratings for the tires.

The tires in your link are 225 75R15 LRD (8 ply) tires rated to carry a maximum of 2540 pounds at 65 PSI. That is the typical load rating for ALL tires of that size and that ply rating at that PSI.

Thanks to you both for pointing that out.

So the Endurance with a E load range and 2833 lbs is better than the NANCO, at least on paper. And I assume better than the TK's that came with the TT.

I have 3 months to land on a replacement tire before camping begins.

As standard on my 16.5k 5er were Marathon Es, talk about an accident waiting to happen. I opted for the Gs, wore them out & upgraded to 17.5" Sailun 637 Hs, no more tire worries.
If I were to trade again they would install at least 1 (maybe 2) load rating more than comes on it before I'll make the deal.OEM tires on any rv are marginal at best.

Over 10,000 mikes on my GY Endurance over pretty hard core terrain, and I can understand how the OP feels, as I have had no success with china bombs ( including Marathons) to say the least. I haven't heard any complaints so far, and I'm happy to be the guinea pig haha. If I can buy stuff made in the USA, I will, because there is a big difference. #MAGA #MCGA

Your reference describes them as having a load capacity of 2540# @ 65 PSI. That's a LRD tire. They may have inadvertently listed it as having a load index of "J" where it really may have a "J" speed rating (62 MPH).

The dealer can't do that and this is the reason why: FMVSS 571.120 paragraph S10.3, The tires on each RV trailer at first retail sale must be the same size as the tire size on the labeling.

It's a "snow ball". The dealer does not have the authority to change OE tires without the trailer manufacturer's permission. The trailer manufacturer cannot allow the tires to be changed because it would change the specs on all other like sized trailers before and after. Also, think tire serial numbers.

Catch 22; The size designation on a tire does not include it's load range. Therefore, IMO, a ST225/75R15E can be installed in place of a LRD without having to change the labeling (They both can be properly serviced using the same tire inflation chart). Again, however, how would the dealer handle the serial number problem? They - tire serial numbers - must be kept on file for 5 years.

A point to remember, up until first sale the trailer manufacturer is subject to all enforceable building regulations and standards governed by the DOT. They can be fined, stiffly. You, as an owner, are not (may not be) subject to those fines and penalties.

************************************************** ***********

Updated 22 Jan 2018;

Realizing some may not be familiar with vehicle manufacturer responsibilities for registering the tires sold on their vehicles, I’m providing this excerpt from the regulation.

“Motor vehicle manufacturers are required to maintain records of the TINs for the tires installed on their vehicles and the name and address of the first purchasers of their vehicles for 5 years from the date that the vehicles are sold. These requirements are intended to ensure that purchasers receive proper notification in the event that a tire is recalled to remedy a noncompliance or safety-related defect.”

Why is the same size GY Endurance 5 pounds heavier than the Carlsile?

Per your similar question on another thread, they aren't 5 pounds heavier, they are 1.2 pounds lighter than the Carlisle tires.

According to the specs I have, the GY Endurance ST235/80R16E weighs 40#. The Carlisle Radial Trail RH ST235/80R16E weighs 35#.

GY has added a scuff guard protector in the Endurance's sidewall which probably accounts for the extra weight. It does not add strength, just durability.

So what is everybody scuffing against with their trailer tires ? He asks innocently . . . . . . .

So you have never scuffed a trailer tire on a curb in a tight turn?

I hesitate to answer that question as it will doom me the next time I take the TT out.

I have had a few utility trailers over the years, currently I have a tandem dump trailer and to my knowledge I have never scuffed on one of them.

Hauling grain on the farm with various truck/trailer combinations I have done a bit of scuffing.


Scuffing, sounds more ominous than what we are discussing here, doesn't it ?

There are two kinds of RV owners. Those who HAVE scuffed a tire and those who WILL scuff a tire.

Doesn't that extra we 20 pounds decrease payload?

That is the same as motorcycle riders, there are those who have dropped their bike and those who will drop their bike. I am the former !
