Those are OK giant 5ers whose owners are willing to cruise nice and slow. They are a trailer-only tire with a modest max speed increase to 75mph, meaning 65 and you're golden. The Michelin Rib is a proper commercial truck tire with 100mph speed rating, which means I can actually keep up with highway traffic in Texas without fretting the whole time about heat build-up. Granted, the Rib is "only" rated for 3042 lbs in single applications, while the G614 RST is at 3750, but I'd be concerned if I were outweighing that anyway. For instance, on my 20k dual tandem gooseneck, I'm running 8 Ribs (at a max dual load of 2778 each) for a total of 22,224 lbs, already over the trailer capacity. I don't really need to trade speed rating and common availability to bump it up even further overweight to 27,320 lbs (at 3415 each in dual configuration), nor would I bet most people would need the overhead.
That said, as long as you're willing to take it easy on the highway, you can't ask for any more load capacity...

I'm a dual axle so the RIBs are under rated for my weight. I need the 3750 each. My toyhauler is almost 40 feet long and 16k so I don't usually go over 75. However, the G614's aren't trailer tires. They are commercial truck tires for tow trucks and the like that still take a 16" rim. They just happen to also be rated for trailer use. Trailer tires, aka "ST", are total garbage. As for heat, I have a TPMS on the trailer that also measures temp. I can cruise all day long at 70-75 and never see over 100 degrees. Outside air temp has more of an effect on the G614's than load in my experience.

I had seen that recently. I think they re designated them for trailer use as no heavy trucks come with 16" rims anymore. They're all 17.5" now. Years ago you had to really dig to find that they were trailer rated. Now it's the other way around. The ST in the name is new too. My axles are 7k each. My GVWR is 16k as at least 2200 is on the truck via pin weight all the time. The TPMS is from TST (Truck System Technologies). The temp reading is great in case your dragging a brake or have a bad bearing heating up a tire. Love it!

You bet. There is def a difference between brands too. I had a Hawks Head system before this one. What a piece. Always errors. This one has been flawless. Price is right too...
As for the G614's, I just looked again at Goodyear's site. They do in fact now list this tire as a trailer tire but a remnant of it's previous use is still there when you look at the specs and sizing. The tire's size is still listed as "LT235/85R16 G." I wonder if someday they will change this to ST235/85R16 G???
