Tire Tread Depth?

[Gone Exploring Again]

Hi there! Looking for help guessing tire tread depth upon blowout for warranty. I've searched, and the best I have so far is that a typical 205/75 R14 starts at about 8/32 or 9/32. Tires were about 3 years old, maybe 20k of mileage (of use - may have more time on shelf), has been in hot (+105) and cold (0). This summer had concurrent days of blowouts on the front tires - one on the left, next day on the right. Any idea what *depth* the tire tread may have been when they blew? They just want an estimate, but I need it to be a realistic estimate. Attached is zoomed in pic of shredded blowout, both sides. I know there are lots of reasons the blowouts may have happened (too full, not full enough, load imbalance, made in Chna, incorrect calibration of braking, ST vs LT, lol). The depth is my missing link at the moment. Any help appreciated!!
(Including pics of both tires...brutal)

I don't know how how anyone could even hazard an edjucated guess. Driving habits, road surfaces driven on, wheel alignment, bearing conditions, single or dual axels, etc. I'm guessing the tires have been disposed so you can't measure them now?

if the other 2 tires are still the original tires just measure one of the survivors.

The designated tire size in the OPs post is 205/75R14. That designated size is a passenger tire and is built by at least two dozen manufacturers.

There is no way to know what your tread depth was by anyone other than you. The other tires not destroyed could give you an indication but still might not be correct if you had some suspension anomaly, impacts on the affected tires etc.
The tires you have should be adequate to support your trailer and the ST (trailer tire - not passenger) size you indicated is rated at approx. 2100lbs. per tire load range D. Again use, abuse and several other factors affect your tread depth....
