What is it about this subject that causes threads to close sooooo quickly?

The last lasted 8 hours!!! before it was closed.

So let's try this again, but folks - let's keep it civil.

No name calling, no accusations.

And to the moderators: Please don't close these threads. If you can't remove offending posts, at least consider banning the folks who are violating the rules. I know some people can't help themselves, but it is penalizing those of us who do follow the rules.

These topics are of interest to some folks, and we don't want obnoxious behavior, so if you have an interest - KEEP IT POLITE!!

I think you answered your own question......it's not the subject. It's the inappropriate responses.

Last weekend, I took one of my ST tires to Discount Tire because it experienced a pretty major cut due to a road hazard. While there, I discussed the ST/LT dilemma with one of the more senior employees to get his perspective. I'll paraphase some of his comments:

1. Trailer manufacturers use ST tires because they are cheaper to produce and purchase. When you're selling hundreds or thousands of trailers a year, you can significantly increase your profit margin by using the lowest cost products you can.

2. The tire store deals with several unhappy customers every week who have premature failures of their ST tires. It has gotten so bad, that they have actually been working with one manufacturer to produce a ST tire just for their stores that has better reliability. But he said they don't have enough feedback yet to see if it's working.

3. In his experience, he's seen no evidence that there are "special" treatments, chemicals, additives what-so-ever used in ST tires that are not also used in LT tires.

4. He has personally examined sidewalls of both ST tires and LT tires, and he said that he has not seen any special reinforcement in ST tires that is not already in LT tires.

5. He reiterated that a person pulling a trailer with ST tires must maintain 65 mph maximum for safety purposes. He said even if you have to pass, don't exceed 70 mph for even a short period of time.

I asked him if he had a trailer, and if so, what kind of tires were on it. His response was "yes, a horse trailer, and I retrofitted it with LTs".

If EVEYONE would just agree with me, agree with MY point of view and do what I do then there would be no problem and everyone would be,"appropriate."

FWIW: I purchased a new Keystone fifth wheel from Camping World in March, 2013. Prior to taking delivery, I had CW remove the factory junk STs and install Firestone Transforce HT 235/85R/16 LTs.

One would think that if installing LTs on a brand new 12,000 lb trailer that is designed for STs (per the manufacturer sticker on the trailer)was unsafe or voided any warranties, Camping World would not have installed them. Or at least they would have had my sign a disclaimer.

I love the LTs. They are a by far a superior tire than any ST tire I have owned.

Just the other day we had to buy tires for our utility trailer. The manager of the tire store said he could only sell us ST tires since they were for a trailer.

I've been searching the internet for a PA law that says we must use ST tires on trailers, but can't find anything. All I could find was this:

"Tire standards. A trailer shall have tires that were manufactured in conformance with standards contained in Chapter 159 (relating to new pneumatic tires). See 75 Pa.C.S. ยง 4525 (relating to tire equipment and traction surfaces)."


We did end up with Towmasters (ST). We'll see...

Too many opinions on the subject which causes discussion to devolve into vehemently defending one's own opinion. When it comes time to buy tires, I'm certainly not going to depend on opinions found here. As as a viewer/non contributor on this topic, I have seen both side of the argument so I'll use the info gleaned as info, but certainly not regarding a purchase decesion. Really - you could create a sticky with links to all the closed threads on this subject and have enough reading material for some time. More discussion is only a rehashing of the contents of closed threads, which I'm sure this one is doomed to be as well.

Now that we are being "civilized" I'll add my 2 cents.

We just traded in our 2007 Jayco Eagle 322FKS that had (OEM) Marathon ST tires on it. Traveled all over the U.S. and eastern half of Canada. Put on many 10's of thousands of miles on them (and some really rough roads). Had one blow out.Replaced all the tires after 5 years of wear with Marathon ST tires.
Having said that I personally would purchase ST or LT tires as long at they are rated at least as high as the OEM tires that come with the units.
RV manufacturers are not in the business of producing "junk". Considering the "pounding" that a RV takes going down our "rotten" roads I think they last quite a while.
There, that's my 2 cents worth.
happy trails,

The factory Duro's that came on our Laredo pulled ok but had a vibration to them. Had them balanced and found out why. Off they came for Goodrich Commercial T/A's. Night and day. No more ST's for me!

Having worked in a tire shop for a number of years all I can say about that image is: that would have NEVER left our shop like that. We would have replaced the tire and sent that one back as having a manufacturing defect.

Unless the rim had something wrong with it, but usually replacing the rubber and re-balancing solved it.
