I note with geat interest that the link leads us to a web site where all the tire loading information is according to the published industry standards - with one exception. That exception MIGHT be a typo (It's only off by a single digit.) It could also be that these guys have decided to deviate from the standard. (That's allowed, but those of us who have been in the business a long time do not recommend that.)
And to address Chris's concern: Industry standards are kind of fixed in stone. They don't vary (much).
In the area we are discussing - ST tires, there is only a single published industry standard - The Tire and Rim Association.
However, there are some folks who do not seem to be following the industry standard - and I point out that every one of those is not a major tire manufacturer - and by "not a major", I mean "Not in the top ten" worldwide.
I can understand that this would look confusing to an outsider.
A side note: We would not be having this conversation if the tires were not failing - and more precisely, failing in fairly large numbers. An odd tire failure or 2 can be dismissed as isloated cases.
But the situation seems to be that there aren't any particular brands of ST tires that are immune to this. This leads me to believe there is something else going on - something generic.
I said on the very first post that I think ST tires need to be sized so the loading is at 85% of the rated load - and this thread has not convinced me otherwise. If anything, it has reinforced it.
Changing to a different tire size/Load Range is not a simple process. Higher load ranges require checking the wheels. Larger tires require checking the fender clearances and rim widths. At the top end, there doesn't appear to be a suitable answer.
I wish there were simple answers here. But there aren't.
What ^^^ he said!
ST problems are not just with RV's. Go to the boat trailer or horse trailer forums, or any other forum about tires on trailers. The story is the same. Most manufacturers do not pick the tire, they go to bid with Tredit or Tireco and buy low bid wheels and tires already mounted. We read about the results here time and again.
Some will pretend that a problem does not exist! Thank you CapriRacer for acknowledging that there is truly an issue!
So back to what really works out in on the highway. Many people have posted that after ST failures they went to LT's on there 6K or under axles and problems were behind them.
Many with 6750 or 7K axles have switched to 215/75R171.5 commercial truck tires to put trailer tire problems behind them.
Many with 15" ST have switched the LT225/75R16E's to put tire problems behind them.
So there are real whole solutions!
For those that blame all ST failures on the user, I would question your knowledge or motive.
Chris
