I did research before buying tires for my 5th wheel. I've had problems in the past even with name brand tires. Time and time again in my research it seemed the preferred tire is the Michelin XPS Rib. The RVers had nothing but good things to say about the tires.
I bought a set and only have about 400 miles on them during the past year, I'm satisfied with them so far.
I've always used LT tires on my TT and now on my 5th wheel.

Look into the Maxxis tires in your size and weight range. Many of us are very happy with them.

I don't think you can get LT tires in a 13 (185/80/D13).
Many here on the Forum have had good service from Maxxis ST (trailer) tires which are available in your size..
If you want LT tires you will need to also buy new larger wheels/rims and then there may be a clearance issue.

Your ST185/80D-13 is a bis ply tire. I would go with a radial.
Another good tire for a trailer is the Kumho 857 and is advertized for commercial use. They come in a 185R/13 D load range with a 65 psi rating. Your wheel will need to be 65 psi pressure rated also.

Whats wrong with bias ply tires that make people not want them. Radials have softer sidewalls than bias and will let the trailer sway more. Thats why they have bias on them.

Radials run much cooler/less rolling resistance at hiway speeds and track the tow vehicle with radials much better than the old bias ply tech tire.
As far as a radial tires having a softer sidewall that may or may not be true. A proper load range/load capacity radial tire has no trailer sway.

Many years ago I remember a friend putting bias ply on the rear of a car that had radial on the front. He wondered why the back end of the car wandered all over the road. He was told that the bias ply sidewalls were softer than radials.
I also recomend Maxxis.

I ran a tire shop at a construction company. Everything from wheel barrow tires to 35 ton pay haulers. 988 CAT loader. Any kind of construction equipment you can think of, I've probably changed one at one point. We ran bias ply on things that took side loads due to the stiffness of the tire to support it. Bias ply on the rear of the car will make it loose because the whole tire will flex, radials will flex the side wall leaving most of the tread on the road. I don't go fast enough with my TT to need ALL the traction that the tire provides. If I did I'd be in trouble. I take it easy and stay under 65 mph. Most tire manufactures reccomend inflating 5 psi under the tires rating.

The reason for the wandering was tread squirm. Radials have steel belts that prevent it. Bias ply construction actually enables it.
To the OP. 13" tires severely limit your choices. If at all possible, I would bite the bullet now and put the largest possible rims and tires on it. 14" will be better, at 15" you will have even more options.... 16" is the best, but I doubt they would fit.
Here's a tip fo future TT purchases. Buy one that has 6 lug rims. They almost always have 15" rims/tires on them but,,,, 16" will bolt right up making a upgrade to the best easy.
