Goodyear Marathon Trailer Tires

MM49
you apparently did not read through the specifications .
The G26 225/70 R15 load range D is the heaviest duty tire readily available in a 15 inch size .
If you do the research you will discover your error .

The way I see it, it's all about "odds". As my old Dad would often say, "every thing is a calculable risk".

Here's an example....new client showed up at the barn last night. Two horse bumper pull trailer....just got in here to the midwest from California. Pulled it behind a ecoboost f150.....so I got curious after they left and looked at the tires. 2009 date code carlisle ST tires. And yep, he made it, no problem from the west coast to here.

Point is, I'm not silly enough to say he was for sure doomed to a roadside failure. But what I "am" willing to say, is that his odds of having a failure were greater than if he had "new" LT tires.
That is all I am trying to point out.....there are certain choices we can make that may in fact improve our odds.

Do your homework, and choose carefully. And best of luck to you all, I really do wish you safe towing.

MM49, enjoy your ST tires. I think we've all seen what your agenda is here. If you like them, that's fine, but your argument that LT tires are not appropriate is not very convincing. You do realize that you also have to consider what the axle is rated for don't you ?

I would suggest to new folks looking at this whole subject, go crawl under your trailer and see what your axle weight capacity is. Also, consider your wheels. In order to get into a 15" wheel that will carry the load that an LR E tire would support, you are likely needing to have a 6 hole, 15" rim. Some are, but many in service on RV's and horse trailers, are 5 hole wheels. It's a "system"....it's not just one component.

Look to the post at the top of page 3 in this discussion .
The information is there .
Goodyear Cargo G26
size 225/70R15 load range D .
106 mph speed rating .
only needs 65 psi to get max weight rating
2450 # weight rating on the tougher LT scale .
33 pound tire weight due to more cords and rubber than any ST tire E rated or otherwise .
made in Germany or france
readily delivered from tire rack within 4 days of purchase to your local tire installer .

A smaller tire with a lower load rating. wrong in both directions. Add the fact that the Cargo is not rated for trailer use and you could ge t wrong in all three directions.

So show me a 225/75/15 E is a LT tire that has the loadrange of a ST tire, silence.........

Are you sure your 15" wheel is rated for the 80psi and weight rating ?
Many, if not most, may not be.

You want load range E, look to a 16", 6 hole RIM and tire. And axle rating too.

well stated, gmwphotos .
more folks are starting to realize that ST tires are just a cheap over-placarded tire built to a lower price .
The folks with the ST tires are reporting the failures .
The folks with the LT tires are reducing and eliminating their failures .
The folks with the maxxis posts are proudly posting about their brand new purchase of maxxis .
What those folks did not do is search the forum and discover that the maxxis ST tires are failing also .

Lower pressure for same weight rating results in a less stiff sidewall and can increase sway. ST tires are designed for trailers, where LT tires are designed for pickup trucks / vans

Using that logic, how do you reconcile that so many trailer manufacturers fit and/or approve LT tires for their trailers ?

Never seen that before, not saying it isn't true, but every trailer I've ever purchased (travel trailers, boats, utility enclosed, and car haulers) have ALL had ST tires on them. I would assume that lower priced trailers would have lower priced tires. ST tires do cost less, so therefore it would make sense to me that a lower priced unit would have ST tires. LT tires can certainly be used for trailers, they are rated for trailers, but with some sacrifice of sidewall stiffness.

An LT tire is a better tire, it offers better traction for the tow vehicle, nicer ride, designed for cornering and braking. An ST tire is designed to follow along on a trailer. Traction is not as important, so the sacrifices in traction and ride comfort translate to stiffer and better for a trailer.

I already said, given the choice, I would run LT tires on my trailer, they are of superior construction and I trust them more. But the question posed to me is WHY an ST tire is better for a trailer, and I still feel an ST is designed better for a trailer then an LT.

I have in front of me, the owner manuals for both my Titan horse trailer and my LoadMax equipment trailer. Both state LT tire are approved. I am getting ready to buy a 4Star horse trailer, I looked at their owner manual online, they too approve LT. I've looked at Kieffer Built, and Logan coach manuals. They too approve LT.

In the RV world, Airstream and the new Oliver come to mind as companies ( as well as others ) fitting LT as original equipment.

The handwriting is on the wall, and it's scribbled in great big letters....."when you want to step up from cheap"......the step is from ST to LT.

Cheap. That's all we need to know about the subject.

I have better, and safer things to do with my time than sit at the side of the road with 18 wheelers zooming by a couple feet away while I change a "cheap" tire.

Hey those of you who want to run ST's...knock yourself out. Good luck with that. But let's not try to confuse the issue to newbies by throwing nonsense around about some superiority of ST tires. Their "strength" is in their low price point.

So show me a 225/75/15 E is a LT tire that has the loadrange of a ST tire, silence.........

Just picked up my two new Maxxis ST205 R75/15 D-rated 8-Ply. Made in Thailand in Dec 2013. Mounted, balance and tax = $136 each.
