Replacement tire questions: PUP
We just bought the PUP in my signature from my FIL. It sill has the original tires on it (Loadstar STR185/80D13). We're planning an ambitious adventure of just under 1,200 miles round trip in a few ...

(unless you're rollin at like 90mph or something.......). More importantly, make sure the bearings are well greased.
Never plan to go that fast. . . will do regarding greased bearings.

The P tire on a single axle trailer is a excellent move. Their very popular with the boating crowd and other PUP owners.
I use them a small 12' tilt bed flat deck trailer with a 1750 lb axle. I also use 15" P tires on a tandem axle trailer. Their not speed restricted as the speed limit on the interstates around here is 75 mph.
Yes a P tires capacity is reduced per fed regs... S4.2.2.2 When passenger car tires are installed on an MPV, truck, bus, or trailer, each tire's load rating is reduced by dividing it by 1.10 ...... .
FYI in case you didn't know your ST185/80D13 is a bias ply tire and not a load range D at 65 psi. The D at that spot is a bias ply designation. Mine are both. Bias ply and under the tire size it says, "Load Range D".
Maxxis has a couple of 13" commercial grade LT tires in the U-168 Bravo. Check them out to satisfy your wheels pressure and width requirements.
good luck on your search.
Thanks for the help. Unfortunately, Maxxis radials are only load range C in 13" and way underrated for my trailer.

If staying with ST tires you can go up to load range D if it makes you more comfortable. The originals are probably load range C.
Definitely get radials.
For such a light load any brand is probably fine.
Mine are actually already load range D. From the posts I've read, this is one of the hardest sizes to find because it only applies to the heaviest PUPs, and there just aren't that many of them out there.
I'd love to go to a 14" wheel with 205 size tires but I'm not confident I've got the clearance and dread multiplying my problems. I learned a long time ago with trucks and trailers that anytime you change something from stock, there's almost always unintended consequences.
My GVWR for the PUP is 3,500 lbs. I don't see any load range C 13" tires that come close. In fact, most of the load range D 13" tires (including the ones that came with it) fall short of that total.
