So it is not advisable to swap unless you go bigger, and that is what the dealer was looking at; was I staying at, or exceeding the load limits of the tires being replaced.

My original size tires had a load rating of 1360 lbs each (175x80 13) but on the lifted trailer I was able to go up to larger 15 inch tires that have a load rating of 1653 each. And from using them for a few months and taking the trailer off-road, I have not had any sidewall cuts due to sharp rocks. That is why I dumped the ST tires.

And when I was at Stanley Lake, two other off-road trailers a Flagstaff and a older Fleetwood(?) both had, from the factory, LT tires. But they had the clearance from their lift to accept larger tires.

I can say I have noticed NO difference in towing the popup on the highways or two lane roads with the truck tires vs. the Goodyear Marathons I had from the trailer dealer. The Marathons just did not like rocks. If not taking your trailer down trails where you have to climb a ledge or two, I would say the Marathons are a great tire. (Personal opinion.)
"The one major difference between ST and LT tires is that for the same size, a ST tire can carry a lot higher load vs a standard or LT tire. " You failed to mention the MAX speed limit for operation of ST type tires is 65 Mph while most LT in RV operation have a speed limit of 75.

If you are considering changing from ST to LT there are a lot of things that must be taken into consideration. I have a blog post just on that topic.

I had Marathons on my Jayco before, never a problem. So I stuck with the Marathons ST. Black tire is one of the largest Good year dealers around. I was surprised when he said he would not sell me anything else. so far I have atleast 4000 miles on these and they look brand new. I just figured that's there business and they know what they are talking about. He also made me balance them or he would not sell them to me, he said that if I want to go somewhere else that would be fine. But they will not do something that they thought was unsafe. Made me feel like I bought the right tires for my unit.


Our dealer is local & has 3 stores great prices but told me they would also absolutely NOT put LT tires on my camper. Tried another Goodyear dealer & was told the same thing.....

We are upgrading from a E rated to a G rated tire just for that reason Peace of mind. Ive done a week of research and cannot find a G rated Radial made here in the USA with (maybe) the exception of the Goodyear unisteel G614, but at $350 its a lot to pay for tires that have a "6 to 12k milage range on them.

Speed kills trailer tires. Most ST tires are designed to be run at a maximum of 65 mph. Higher speeds cause the buildup of heat, which seriously impacts the life and wear of the
trailer tires.
If you don't have a TPMS you should

I've seen LT tires on FW's from the factory. Wonder if they would replace those with LT's???

Do you have the weigh slips showing that the LT can carry the load?

I said I've SEEN them with LTs from the factory. Several at an RV show a couple years back when I was curious about different tires and was paying attention to what was being installed. So....no, I don't have weight slips. IIRC, I am thinking they were mostly 235/85-16, meaning they'd be rated for 3042 each in a LRE. This would seem to be satisfactory for most FWs with a GVWR in the 14,500 range when accounting for pin weight.

I'm no tire expert, but I can tell you that I for one would be WAAAAAAYYYY more comfortable towing my camper with LT tires that were rated to carry the load. And I wouldn't cringe and glance at the TPMS monitor every time I accidentally break 65mph on a downhill run.
