Buy two, set them aside...next paycheck buy two more and then two a third time.

 

As mentioned, you can mount two at a time. Or even one at a time if that is what the wallet allows. However, if you are towing it that old adage about the "chain is only as strong as it's weakest link" does come into play.

 

If it's a budget thing, I'd get the Sailun load range G. They are an excellent less expensive alternative to the Goodyear's. If I knew about them when I bought my Goodyear's I may very well have opted for them at about $169 per. I read nothing but good reviews on them on all the RV forums I'm on Randy...

 

ditto on the sailun's !!! well reviewed replacement....

 

This is a tough thread to read. But, of course, I have an opinion (as we all do).
. . .
ST tires should be used on travel trailers and 5th wheels, and not LTs. ST tires are designed for travel trailers and 5th wheels: The trailer suspension design specs assume that ST tires will be used. etc. As someone noted a long time ago, going to LT tires will change the design analysis of your trailer..
ST tires should be used on travel trailers, and Lt tires should only be used for trucks.
. . . .
that's it . . . . ken. . .

 

All your points are completely incorrect and that my friend is it... Not opinion. Fact. Thanks for playing though!

 

I guess the mfg's didn't get that memo because some rv's are coming with LT tires from the mfg ...

At least my mfg put them on and I LOVE them...

Now, can a mfg call a tire an LT if it's not ? dunno, but maybe they can mix and match to have an LT RST

so far, we can still use what we want to until the next executive order comes out

 

Carlisle says eat mor chikin so it must be true!

 

If you can ever get to see a G614 prior to install, look at the difference between one and say a China bomb. HUGE difference. The GYs are twice the weight and MUCH better made. I have a TT toyhauler also that has ST tires on it, mainly because they are Maxxis and fall well within the weight designation. As for heavier 5ers, I will use the heavy duty LT tires from now on.

 

LT tires will flex a little more than an ST tire.

That makes an ST tire for a trailer more desirable. But with the wording of China on the ST sidewall that makes the court sway its opinion to the LT.

 

Right! When I took my brand new tires and rims off my RV and to the shop to get the GY's put on, I had to load all 8 in my truck bed. I was astounded to find that the ST tires still mounted on the rims weighed FAR less than the bare G614's! Ken has clearly been reading the ST tire manufacturer's literature and believing it. LOL. For some, the coolaid is tasty and easy to swallow. Anyone in the know, knows its just their marketing. And as jdadamsjr pointed out, LT tires come on some better rigs or can be ordered from the factory. Heck, Michelin even states that their XPS Rib is suitable for trailer use. Goodyear re-designated the 614 for trailer use when it's LT use became obsolete. ST is not a better design for trailers. It's a marketing tool for it's manufacturers and a way for RV manufacturers to use the least expensive tire possible...

 

Not true Scott. If you ever had them unmounted side by side, you'd see the ST will flex like a cheap bicycle tire and the steel carcase LT will hold its shape even empty. The LT is much stiffer but one of the bogus marketing lines from ST manufacturers is that they have a stiffer sidewall which simply is not the case...

 

What I found out too late was the Carlyse 15" tire was crap, as it came on my brand new Forest River 5'er I figured they had it capably equipped. It took about 4 trips for me to replace 3 of them with GY Marathon crap tires, but on the interstate having just blown 2 tires you don't have many options.

I have now gotten the Maxxis tires (I think) as I wasn't thinkning I would see this superb post I wasn't ready. So heres a million $$ question, what is the biggest/BEST tire for a 15" rim?

My, apparent, issue is the tires are recommended (or the dealer mentioned this) for speeds up to 65 MPH. Well I took it to Myrtle this summer and ran it 75-80 mph in July and they have done fine ..... so far. I'm fearful that I really need to get some 16" rims for my style of driving, plus the fact that I only have about 600-700 lbs "cushion" per tire of the load limit.

I've had 3 tires total blow out and they all came after crossing a bridge, we all know how great and smooth those transitions are when pulling.

 

True, but you need to compare apples to apples. You can't compare the steel sidewalled Goodyear and Sailun to a polyester sidewall tire. I had the Loadstar carriers on my trailer that were G rated but still had a poly sidewall and I'm replacing with the G rated Sailuns that are steel. It's a different animal. Any LT that doesn't have steel sidewalls will flex too. Again the goodyear is still rated as an LT, but the Sailun is rated as a truck tire, designed for trailers, but with no LT or ST branding.

 

Unless you upgrade to 16" rims, the Maxxis tires you have are are the best in the industry for a 15" wheel and the only ST tire without a huge following of hatred in the RV community. Had them on my first TT and they performed flawlessly!
