Uhhh, not quite. Check the Goodyear website. Unisteel G614 RST. It is designed specifically for straight line usage and is not recommended for steering. Pick one up - - but put on your back brace LOL. The difference in the flexing of the tire is much different. Yep, expensive - - but so is replacing a cheaper tire and fixing what is all messed up and the hassles of a blown tire in the middle of the Yukon. If your rig is not that heavy, it can, and should be run at a lower pressure - - Goodyear site has a chart for pressure versus weight. One must weigh all this with the recommendation that tires, pending exposure, be replaced every five to six years. I think many tires blow because we have pressed them beyond their life cycle even though the miles are not high.

 

Not really clear where the disagreement is about...? I think we're in agreement about the G614. I never said it was made for steering, or anything else questionable about it.

According to the website below, the G614 is a trailer tire, and a heavy one, that is absolutely not designated as an "ST Trailer tire". GY calls it an RST and this is not the same as ST.

I just traded for a 2008 Surveyor that came with the original 15in tires/wheels. I have no intention of using them after getting the camper home.
My concern is that there is not much space between the tires as mounted now. After a talk with my trusted Firestone dealer, I am going to put a set of TransForce HT 225-75R16 on it. They run 80 psi. I have a new set of 16x6 white spokes here. The book shows the tire outside dimension to be an inch more than what is there now. That should leave me an inch and a quarter clearance between the tires.

I have been running the TransForce 235-85R16 tires on many other enclosed trailers and the 40ft Challenger camper for a few years and have had GOOD track record with them.

 

Previous owner had upgraded my 5th wheel to 16's, and when it was time, I put some Cooper SRM II's on... highly rated commercial rib tire and not too expensive.. I recently looked up the tire on their web site and it's been replaced. It may be the Discoverer HT3..

 

Same problem here. The factory 235/85-16 ST tires had very little space between them...like a half-inch.

I replaced them with 235/75-16 Duravis tires (as noted above), and it gave me a bit more room.

 

Trailer tire threads and oil threads are becoming strikingly similar.

If you park your trailer for months or years on end then I dont think it matters what tire you put under it. Tires cant sit unused.....and the longer they sit the more likely they'll have trouble.

In saying that, I just saw a lawn gardener the other day with BALD 15" trailer tires. I think they were cheapo's too. Anyone who runs bald trailer tires isnt spending more money for the "better" tires. So anyone who says that 15" tires are no good might want to call this guy up and ask him what he did to keep his tires from falling apart.....besides using his trailer ALL the time.
