For me it is very simple. Posts about ST tire failures are common. Posts about LT tire failures are rare.

That could be at least partially attributed to the fact that there are millions more ST equipped trailers than LT equipped trailers.

Except most TVs have LT tires pulling a trailer with ST tires. How come you don't see the same complaints about these LT tires? The ratio will be about the same. Many LT tires on pick ups are also under a heavy load that is near to their capacity. They also drive over the same roads under the same environmental conditions with the same speed.

I've never had an LT tire fail while towing, and they get many more miles than the ST tires do. I have had six ST tires of varying brands fail over the years. The common denominator on the ST tires. Made in CHINA. Your argument is fallacious.

So sorry, I thought this was a thread about tires on trailers. Trailers subject tires to different use and conditions than tow vehicles such as long periods of sitting in storage.

Whenever I read posts about tire failures my first thoughts are age, under inflation, and overloading.

lt vs st production numbers

**In 2014 there were about 310,000 trailer sales. A majority of these came with ST type tires and some with LT type tires. While I could not find specific figures I believe that almost all ST type tires were imports. I would estimate this represents almost 1 Mil. OE tire sales.

In the US there were about 7.6 Mil cars and 8.7 Mil light trucks and 400 thousand heavy trucks produced in 2014. There were about 253 Mil. passenger tires plus 33.6 Mil. LT tires and 23.1 MIl medium and heavy truck tires sold at replacement and OE.**

ST tire sales are but a drop in the bucket.....which is one reason our domestic tire makers stopped their ST tire production years ago or as Carlisle and Goodyear moved their ST tire production overseas as most of the other niche tire products such as ag tires/construction vehicle tires/ATV/lawn service equipment tires/etc.

As I have stated many times....there are MILLIONS of ST tires on the road. You will hear more complaints about ST vs LT on campers because of shear numbers. In towing over 250000 miles only 1 tire failure...a US made GY Marathon and that was after hitting a bad pothole.

FWIW, I noticed Grand Design is advertising LT tires on its FWs.

No where on their web site does it show LT tires being offered.
Westlake E rated are OEM and an option for Goodyear ST 235/85/16 G614s.

GoDucks,

The Goodyear G614 is an LT tire. The only size it is offered in is LT235/85R16 (G). BTW They are currently offering a $20 rebate per tire for this model through July. Here's a link to the rebate page:

Oops. Need to do better research.

Certainly a trip down memory lane; Chuck&Gail, Fast Eagle, where'd they go? To the post: didn't change anyone's mind then, won't change them now.

Well as I have stated many times semis run the same tire body in all positions, tread design may vary, I will tell you that drivers when the tread still has tread, but is getting thinner will be moved to a trailer position for a while before it is capped.
My 5er has a GVWR of 12,360# my LT235/85-16E's have a load rating of 3,042# each for a total of 12,168#, at 20 percent pin say 2,400#, I have 9,960# on the 5er's tires, less than I have on the TV tires.

You also have the much cheaper in cost, but high Quality Sailun S637 tires...MUCH cheaper cost than the G614's..just an alternative if cost is a factor
