27 Dec 2021 Update
A recall on Sailun's caught my attention thus (eventually) I ended up back at this thread--time for an update.
First, the recall information is here: https://www.nhtsa.gov/recalls?nhtsaI...000&refurl=rss If understand the posted recall information correctly, the DOT codes 2020 through 4120 on the applicable tires mean they were manufactured between the 20th week of 2020 and the 41st week of 2020. Mine, as noted in post 1, were made the 49th week of 2019 so (thankfully) the recall does not appear to apply to me.
Tread wear update: the Sailun's have ~7900 miles on them. I measured them this time with a digital depth gauge. Specs online state the original depth is 10/32, so I must have done something wrong on my first measurements as I wrote the tread was 9/32.
What the data shows is the worst wear is on the inside, street front tire and there's slightly more wear on the inside. That's no surprise as it carries the heaviest load due to how the trailer is configured. Even that wear is less than 1/32". (I'll be rotating the tires soon.)
Notes:
"Wear" is calculated by subtracting the actual measurement from starting tread depth which is now considered to be 10/32 (or 7.93 mm).
Each measurement was taken four times and the results were averaged.
There are four "tread" lines in each tire, thus four measurement points per tire.
Here's the data
