Part of me is just tempted to run a decent name brand E rated 10 ply truck tire in LT245/75/16 and call it a day, is there really much to gain by using a designated "trailer" tire? Thanks.
This is what I do with all my trailers, NO more ST tires at all
My 8 lug trailers get Boar wheels w/ 19.5 tires https://www.boarwheel.com/wheels/
Their sidewalls are made to flex for dual or triple axles when turning
A lot of RV's have great service out of Sailun tires. I just put my third set of Sailun S637 235/85/R16G tires on my 5th wheel. $180 each; you could spend a lot more, but these work well. You can get them from your tire dealer or Walmart on-line. G may be a little overkill for your 10k boat, but sure wouldn't hurt. I'm not a tire expert, but I think ST tires are best. I think they have construction designed to handle the scrubbing when a multi-axle trailer turns.
I’m on my second set of Sailun ST all steel radials on our 12/13K lbs TT. In my opinion they are about as bullet proof as you can get in an ST tire.
Of course for the OP’s boat trailer Goodyear Endurance ST tires should be a good match.
Been pulling trailers for 40 years and in that time I have never had a LT tire sidewall fail, but have had more ST tires fail from tread / cord separation then I can even count. The only ST tires that seem to last are the All Steel $$$ ones. FYI, I always make sure the tire load rating is matched to the trailer weight rating, and that is my professional opinion, as a Master over the road truck technician.

Same. Never had an LT fail, but I cannot say the same about the STs I've ran. I'll only run LT tires on my trailers and replace them at six years of age (not use). YMMV.

Exactly. LT tires have to meet very specific DOT safety requirements since they are designed for use on motor vehicles. Most of your ST tires are garbage, and I won't touch a Goodforayear tire. My plan is always to find a quality LT-E rated tire that will fit my 15" wheels, which can sometimes be hard to do but it's worth it.
In the article, they say most trailer tires are rated for 65 mph. I believe that used to be the case. Today, a lot of trailer tires are rated above 65 mph...just have to look at the specs.
Also, they say if you want to increase the speed rating, just add 10 more psi....I'm curious how the writers came up with that.
I've read several articles comparing LT to ST and I've never seen any test data or actual specifications for differences in sidewall strength or components. So I still have no solid info confirming one is better than the other for use on a trailer. IMO, adhering to a tire's load rating and speed rating is the most important since those are actual specifications.
"High Speed" is used to differentiate the M8008 ST Radial from other products we offer that are intended for industrial and/or commercial use, in slow speed applications. The Maxxis M8008 ST Radial carries a "Q" speed rating (99mph) . However, according to the Tire and Rim Association, the U.S. tire industry specification authority, inflation pressures and load specifications in general for any ST Radial trailer tires without a service description, regardless of the manufacturer, are designed and rated at 65 MPH. However, if the speed is higher than 65 MPH, the pressure and load need to be adjusted according to the following guidelines:
From 66 to 75 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) but requires no load adjustment.
From 76 to 85 MPH – the tire inflation pressure needs to increase 10 PSI (not to exceed the maximum PSI the tire is rated for) and load should be reduced by 10%.
We hope this information is helpful. Thanks for your inquiry and interest in Maxxis Tires.

I have run a LT bias ply on my 20 ft open deck car trailer for many years with out issues.
That was doing 12 hours drive above 65 MPH many times.
They need to be replaced because of dry rot then next time I need to use it.
But as someone pointed out LT tires need to go thru DOT so they will be going back on when the need comes.
