Westlake Tires - Event Date: 17 Jul 2020 - 30 Aug 2020

I have the 15", load range C, Westlake "snow" tires on my 2016 RP171 HRE.  They have a single load rating of 1985 lb at 50 psi stamped on the tires.  I had to get them balanced right off the bat and have pulled it at max gross weight (3200 lb; 400 lb of this on the tongue) for about 18,000 miles at frequently checked 50 psi cold with no flats or tire failures.   I usually drive at 65mph if road conditions allow.  However, the tires have developed an odd wear pattern.  When I run my hand over the tread it is noticeably rough feeling.  The outside blocks tend to be taller on the front of the block (10 32nd's vs 6 32nd's, passenger side) but taller on the rear of the blocks (driver side)!  It's hard to get a reliable tread depth measurement because none of the adjacent blocks, outside, center or off-center are the same depth. Given the roughness, they are wearing evenly on outside compared to the inside but the small individual off-center blocks tend to be shorter than anything else.  The wear pattern makes no sense to me.  Has anyone else seen this odd wear pattern or have a suggestion as to the possible cause?  Tire shops just scratch their heads when I show them.  I was just figuring they were poorly designed cheap tires.

Consumer reports and NHTSA rate vehicle tires but I haven't seem ratings anywhere for trailer tires.

My TPMS mounts on the tire valve, so the indication of temp is the air coming to that valve. It gives a trackable temp, I would think the heat it would not sense well is the hub, not the tire.
