If you have your TPMS set up correctly, and it's a quality unit that gives frequent updates on pressure/temp, it won't predict a blowout unless you consider the warning that the tire is losing air or heating up a "Prediction".
I can't speak to other, cheaper TPMS systems but my TST 507 gives instantaneous warnings when I remove the sensor to add air due to temperature changes. If you don't get a pressure update for 10 minutes that means you could pick up a nail or piece of scrap metal then drive for 10 miles (at 60 mph) on a tire going flat.
Not all TPMS systems are the same and usually there is a reason why some are less expensive than others.

You may/may not get an early TPMS alert. Maybe for temp but probably not pressure. Many have reported tread separation and never lost a pound of air. Mine didn't alert when they separated. The tire was still aired up perfectly.
I noticed mine jockeying it around the house getting ready for a trip.
I'm just glad I didn't lose parts of the trailer like many do when they fail.

TPMS will only warn if a tire loses air pressure. They are not designed or intended to sense or warn of a possible belt separation. I have covered the process of how trailer owners can do a "free spin" inspection to learn if there is a separation starting.
Belt separations take many miles to develop and grow.
It is not magic. Tires that fail do so for a reason as I covered in the post on why tires fail.
I have covered the reason for a majority of the belt failures in tires on multi-axle trailers i.e. Interply Shear.

The tire dealers where I live don’t sell anything for trailers other than the China stuff. I’ve become resigned to replacing them every few years.

I'll bet you can get them to order the good tires for you.
Just tell them what tires you want.

Yes. My dealer can get any tire, next-day. But he always keeps Maxxis trailer tires in stock. This is a mom&pop biz in a small town.
Before I retired, DW would go there for replacement tires on car and truck, and they would tell her if the tires didn't need replacing yet. My kind of business owner.

The Maxxis tires, though made in China, are not China bombs.
I have Hercules SP2 tires on my 5'ver...also made in China, but not bombs, either.
There are lots of good tires coming out of China...just have to know which ones to stay away from.

Right. I have been buying Maxxis for years. I believe mine were actually made in Thailand.

X2. All the Maxxis ST tires I've seen are made in Thailand.

Sorry... Hercules suck too. Had all 4 of mine develop huge. bubbles in the tread and sidewall.
Every Maxxis I have bought have been made in Thailand.
They make great MTB tires too!

China... Thailand... not much difference.
Remember what we used to say about Japan back in the 60's and 70's?

I have 2014 Forestriver Flagstaff 26RLS No real tire issues in 19,500 miles (1 flat from a nail--fixed--fine) It has Westlake super ST tires, a brand I've never heard of. The tread is quite good with no apparent dry rot. What it DOES have is somewhat rounded shoulders (outer edge) which I've assumed was because of the way "rubber axles" turn in (or out) on tight maneuvering. I'm considering new tires before a 6,000 mile trip in 2020. A ny comments or logical opinions? Bill Rinaldi

Trailer tires are free rolling and it's normal for slight edge wear to form after the miles pile up. Also normal if similar wear forms on both sides of circumferential grooves in the tire tread.
Keep them inflated, inspect regularly, follow weight limit and max speed spec on tire, you've probably have more miles left.
Don't overlook a regular "jacked up wheel" inspection where you can look for any possible tread separation. These show up as slight bulging in one area of the tread as you rotate the unloaded wheel.
I personally like to replace tires when tread is half worn. MOST tire failures occur in the last 50% of tread depth whether separation or puncture. If the spare has never been on the ground, use its tread depth for starting depth. As an example, if you start with 9/32nds tread depth the 50% point is just over 4/32nds. Of that 2/32nds is the legal minimum. To me it's not worth the risk of a failure or reduced wet pavement traction to try and squeeze the last 1/16" of wear out of any tire. I replace car, truck, and trailer tires at 50% wear.
Might run longer on a commercial rig but those tires are a whole different animal.
