Carlisle/ goodyear is what uhaul uses.

We have started skipping the "trailer" rated tires. They are so low end they aren't even rated to carry persons. We have stepped up to the Michelin D or E truck tires. Once we did that the failures and carcass rot stopped.
The E range stuff we have is all 16" rims. From memory 15" rims have a few D range choices. I don't think LT tires are a good choice for a 7k axle though. In fact I don't recall seeing a 7k axle with anything less than a 8 lug 16" wheel. That's a 14k tandem axle trailer-which is a custom cargo/car hauler.
OP doesn't state if this is tandem or single axle. If it's tandem axle that's 3.5k per axle or 1.75k per tire. This is about max for C range.
If you look at the tires they use they are built especially for Uhaul. We as consumers can't buy them.Carlisle/ goodyear is what uhaul uses.
I am a little confused by these two posts. I have a trailer with 16'' wheel so that is why I am asking. I've thought about LT tires for it when the time comes.
The subject says "7k car hauler". That's two 3500lb axles, which usually means 15" wheels, and either 215 or 225 size tires.
My experience is this: Bias ply trailer tires are durable and great for short hauls around town. However, they are VERY picky about alignment, and I've had them wear quickly (less than 5000mi) on a single axle boat trailer that didn't wear radial tires at all. For longer runs like the OP is suggesting, and especially for a two axle trailer, I'd recommend sticking with radials for best wear.
I am done with TL (trailer use only) tires for any trailer I plan to keep and use. They are generally made as cheaply as possible no matter what brand you buy, and unless you use Load Range D or E 15" trailer tires, they are NOT better in any way than normal (P-rated) tires. Even going with a name brand trailer tires (Goodyear, Marathon) has not worked out well for my friends and I.
We now use P215 or P225/75R15 tires on all of our car and boat trailers, and LT rated tires on heavier trailers with 16" wheels. The exception is one set of Goodyear G614's that I have on my Gooseneck. The G614's are Load Range G, and I bought them with low miles off CL for $100 each. They are over $300 each new, and are really heavy tires that wear like iron and hold up GREAT, particularly when used well under capacity in lieu of a LR E tire. (Not helpful to OP, but perhaps to others...)
We've experienced no tire failure problems with the non-trailer rated tires, even on tires that are 10+ years old. In my experience, and by most mfg's recommendation, trailer tires that are 5 years old should be replaced. They may be fine for around town, but I certainly wouldn't take them on a longer trip... The last set of P-rated tires we had on the car hauler were P215/75R15 Goodyear RT/S's that were bought off CL as a take-off set of wheels and tires from a new (at the time) Jeep Wrangler. (~2000MY) They lasted 15 years before weather checking and wear prompted their replacement about two years ago. We replaced them with P225/75R15 Cooper Discoverer H/T's. No issues so far.
