LT tires vs. ST tires - Trailer Life article

This month's issue of Trailer Life discusses travel trailer tires and the differences between ST tires and LT tires as well as some brand options.

And in this article, the author issues a resounding "NO" to the use of LT tires upon travel trailers.

June 2013 issue, " Trailer Life" - author Tom Walton...

Well.... you have to believe it if it's in print!!

But then again I still use bias on the old Ford, ST on the trailers, LT on the Burb and P's on the DW's DD.

I seem to remember a magazine article that said Airstream trailers were the worst towing trailers.
Caveat lector.

Airstreams are not your typical travel trailer. It is more of a sports car of the trailer world as opposed to a hay wagon that ST tires were designed for. The whole issue about side wall stiffness does not really apply some something with a low center of gravity. If you have seen an ST compared to a passenger rated tire the ST tire looks like a condom in comparison. It looks more like something you would put on a bicycle. The sidewall stiffness comes from 80psi more than anything else. When that goes it takes some trailer with it.

Does TRAILER LIFE claim to be free of bias on behalf of advertising revenue? Biting the hand that feeds it? TL is a vehicle for advertising. And, did they note that once upon a time there was no such thing as an ST tire, that all we had were LT?

Notice that there are no bad RVs. No bad tow vehicles. Or what would constitute the difference between good and bad.

Does it read like a re-hashed press release? ST tires do look good on paper. So long as one NEVER exceeds 65-mph, or, as was recently said by a tire engineer, running that speed on this tire type is similar to running at engine at redline . . constantly. It won't take long to wear down. Was this the main point of discussion, that towing speeds are central in making this kind of claim?

I note elsewhere in the online access that there is advice which contradicts what two tire engineers have been kind enough to point out on this and and some other Rv forums in re tire pressure on TT's (and what the tire and trailer manufacturers recommend).

A tire not good enough for passenger vehicle use is just too badly designed or constructed or tested to be adequate. There are dealers who won't install them anymore and I know of no one in commercial service any longer willing to put up with their high rate of failure.

This is like citing the 80% Rule. Basis is false. Claims made are thence irrelevant.

That's odd......I read that same article, and while the author did have a bias towards the use of "ST" tires on trailers, I did not read "a resounding "NO" to the use of LT tires upon travel trailers."

And then I wonder what trailer tire manufacturer the author is associated with.

Magazines like this represent a certain unofficial authority and must always tow the establishment line. That's their role - to tamp down rebellion. You will never see these authorities support the rebels and free thinkers and innovators.

The tire industry is a big one, and it is tightly regulated by DOT, and as such consists of approved guidelines, specs, definitions and metrics that the industry has agreed upon, and made their investments accordingly. "Rebels" shall not be allowed to upset this scheme! Imagine if the magazine had said, "Fellas, quit buying them inferior ST tires and move up to the LT for your travel trailers." The makers of those ST tires would take a hit and that kind of upset is never good for industry. Magazines exist to serve their industries by providing advertising space. They don't exist to serve readers.

I read the Trailer Life (June, 2013) article several days ago. I will also have to strongly disagree with their findings and recommendations.

Based upon my personal trailer tire experiences in over 100,000 miles of towing my Safari 25FB, I have found that ST tires are junk tires best suited for static display in a storage lot.

I made the switch to 16" LTs about three years ago, and now have nearly 50,000 miles on them without the slightest problem of any kind. I did the first 50,000 miles on three different sets of ST tires. These ST tires provided me with the thrill of three separate catastrophic tires failures on the highway, seven different tread separations, and two loss of pressure situations.

My trailer will never roll on am ST tire again.

Did anyone notice that most (perhaps all?) the photos of the tires in that article were incorrectly linked to the tire descriptions?? :-)

The author did mention the rule about taking an ST to the 65-75 mph range by increasing air pressure 10 lbs above max (so to 75 lbs) and indicated he reached out to Goodyear who agreed that was appropriate. So if 65 is too much of a limiting factor, there's an option with the STs.

I'm still a rookie at all this. I'm sticking with the GYMs provided with the trailer, keeping them at 65 psi, keeping cruise around 62 and will see what happens. I'm not disagreeing with anyone else's strategy - it's good to know people are having success with other options so if I do experience problems despite religiously obeying the manufacturer's rules, I can explore non-traditional alternatives. Who knows - the 2020 models might just come with 16" axles and Michelins :-)

Interesting, I flipped through several back issues and found absolutely no advertising which would be affected by an article favoring either LT or ST tires. I did find one article that advised staying with the ST tires put on by Airstream.

I don't have the magazine yet (rural delivery), so I haven't read the article. However, the Airstream Life editor runs LT tires on his 30 bunkhouse with great success and has publicly said so in his blog.

I write for the magazine and have done so for years. I'm sure the editor didn't agree with everything I wrote in every article. Articles simply reflect the opinion of the author, not some behind-the-scenes scheme to sell advertising.

BTW, I am in the process of ditching my E-rated ST tires for LT tires.

Seeing as how Airstream has offered offered 16" Michelin LT tires as an extra cost option for years and they were standard on the Eddie Bauer trailers, perhaps the article's author should have stated these comments were his personal thoughts and not those of any tire authority or anyone with real world experience towing Airstreams on both ST and LT tires.

Then he would not have had as much egg on his literary face.

Mea Culpa

I had just responded to an email about Airstream Life and my brain just didn't shift gears. Too late to edit it now, though.
