Another tire question

What is the difference between our ST tires and LT tires? I was thinking to put LT tires on my unit... Any thoughts would be appreciated.

LT are truck tires while ST are trailer tires. ST tires have a stiffer sidewall. As long as you stick with G rated tires either will do the job. Did your rig not come with G rated Sailuns?

Your rig is rated 16,000 lbs and came with G range tires. Unfortunately, you will not find any tires other than those rated for trailer use that will carry the load. LT tires in sizes that will fit, will only handle 3,042 lbs, so much less than a 7,000 axle needs to have to get the 7,000 lb rating. If your rig was much lighter and only came with 6,000 axles, you could use the LT tires, but not on this rig.

Yes, I have the G rates Sailuns. Are those good...? I thought Goodyear or Michelin would be a better choice. Do either make a G rated ST tire...?

Your Saiun tires are “top of the line” both in value and cost... no reason to spend more money on G614 GY ...etc....keep me inflated properly, covered when not towing to lesson UV exposure, and two speed at 65 or less and those Sailun tires will last you many seasons.

The Sailuns and the Goodyear G614 are both speed rated to 75 mph. This is the L designation on the tires. This is the link to the Sailun S637 trailer tires, of which there are two sizes, and you will see the L.I./S.R. column which is the Load Index and Speed Rating. The other columns give the rest of the specs. http://www.gosailun.com/MRT/Tire/S637T

I had no idea that the Sailun’s were the top of the line. Who makes them? Which brand of Chinese tires are some people having trouble with...?

When the trailer manufacturer used those Original Equipment tires they locked-in a minimum load capacity requirement. That's because tire industry standards require replacement tires to have a load capacity equal to the OE tires. There are zero 16" LT tires with that load capacity capability.

You can verify that standard by reading chapter #4 (highly recommended) in the reference below.

https://www.ustires.org/sites/defaul...TruckTires.pdf


If you're fully committed to the Goodyear manufacturer you could consider their G114 17.5" low platform trailer tires. They come on many RV trailers with 8000# axles. But, your savings account might balk...LOL!

Sailun is a European company owned by several business men and women that have set out to make the best tires in the world. They just happen to be made in China. Sailun is building two plants in NC as we speak to move a large portion of their production here. They also make heavy truck tires. Hercules "G" rated tires are now being made by Cooper Tire right here in Findlay, OH. Their specs are comparable to the Sailun, however they are new to the game without the track record of the Sailun. For the GY G614s you are going to pay around $275-300 per tire and the Sailun are around $150 installed here. Plus now, the tires have a 4400# weight rating per tire that exceeds most all 16" wheels. Very few problems with Sailun over the past several years.

The Chinese tires everyone is screaming about are the PowerKings, TowMax, etc tires. If you have a chance, literally pick one up. They weigh about 30-32 lbs and then pick up a Sailun or G rated tire. They weigh around 65#. Much heavier made tire.

Where do you find the LT or ST on the sidewall? My new 5th wheel tires are Goodyear G114 215/75R17.5 H rated and say for Trailer Use only on the sidewall?

I did not think I was supposed to say on this forum. We loved our 2017 Montana 3820FK, but saw another brand that really intrigued us in the 2-1/2 years and 100 RV parks and 30,000 miles we traveled, so we sold ours, and custom ordered our new 5th wheel, and it is ready for us to do a walk thru this coming Friday. I have been still helping people with questions about Montanas, and want to stay on this forum.

Those have a metric designated size which is void of a prefix. They are commercial low platform trailer tires and very popular on RV trailer axles above 7500#.

I look at this and other RV forums. So far, I've seen only two reports of Sailun failures in two+ years, and neither were definitively blamed on the tires; could have been road hazards. I've had them on my unit for two years with no complaints or problems. No LT tire can carry a similar load. I think it's fair to say no other Chinese-made ST tire is of equal quality, and if you have any E-rated tires on a MT you're taking your chances.
