Trailer tire blow-outs!

Drop and hook is Russian Roulette on tires. Do a real good pre trip - every trip. Use the type of gauge that @kemosabi49 is suggesting. Buy a good one. Don’t forget to calibrate it too.
AND DON’T FORGET TO HAVE A GOOD BRIGHT FLASHLIGHT WITH YOU. AND SPARE BATTERIES. Tell the mechanic if something ain’t right, if he’s too busy, ask him to sign it out as safe. Then watch what he does, when you’re driving it’s all on you.
Good luck

 

Tires either blow up from heat caused by under inflation or they rapidly lose air and come apart. Do you know which is happening?

I'd guess the former, because that seems to be the main cause.

There is also the chance that your boss is running cheap recaps that the tread is separating.

Get a $35 digital temp gun and start taking the temp of your tires cold, during your trip and when you unload. I'd tell you to run your air pressure at 110-120psi, but it'll turn into a debate. But I'll tell you this. A tire at 95-100psi will run hotter when loaded than a tire at 110-120psi.

Oh, come on you guys, how long you been doing this? Trailer tires were the last stop before a boat dock bumper. I don't think I've ever had a wagon with all the same tires. Worn drive and steer tires make excellent trailer tires. I think inside tires go more, because of turning. "Run 'em 'till they blow", was a familiar saying. Besides, big deal, flat tires were a part of daily truckers life. With tubes, you were lucky if you went a week without a flat. Cushy XXX drivers today,,
