Off season storage on jack stands?

"ST" is a trailer-only tire; "special trailer". Frankly, the vast majority ain't so special; they're junk. If you have anything with 16" wheels, you can put LT (light truck) tires on them and get much greater longevity and peace of mind with them than with most STs. That being said, there are a couple brands of ST tires, especially in the 15" size, that are much better than the rest. Maxxis is probably top of the heap, though they still have the 65 mph speed rating and they do have occasional failures for, seemingly, no reason. Carlisle, which was one of the worst a decade ago, came out with a completely re-engineered ST tire line that is, IMO, the equal of the Maxxis, despite being made in China (Maxxis is made in Thailand and/or Taiwan, IIRC). I have a set of Carlisles on my FW, going into the 4th year, and they have a bit of weather checking, but otherwise look, and tow, excellently. The Carlisles also have a higher speed rating, into the high-70's/low 80's, so that tells you something, too. Not that I tow that fast, but if I stay at my usual 60-65 mph, I should have plenty of "safety margin".

Agreed, 90 percent of the "ST" tires out there are "D" and "E" rated tires that have rightly earned their less than stellar reputation.

However, the other 10 percent are G-rated, ST tires like the Sailun (prefix recently changed from LT to ST), Gladiator, Hartland, etc. These tires are speed-rated from 75 to 87 mph and have an excellent reputation--especially the "all-steel" versions. A documented failure of an "all-steel" G-rated, ST tire, like the Sailun, are very rare.
