I check my hubs every stop by the "heat on the finger method". If I can't hold onto a hub for more than a couple of seconds, then I have a problem.

I discovered a brake backing plate that had broke it's weld that way.....although I didn't know why the hub was heating up at that time. I jacked up the trailer, and the wheel would barely turn because the brakes were "floating" inside the drum. I backed off the brake adjustment, got the wheel to spin freely, let everything cool, and rechecked the hub again after about 20 miles, and then again after about another 50 miles. All was good. I traveled home about another 800 miles before I had that puppy fixed.......I was Indiana when the backing plate weld broke.

Do you mean that you took it off and drove the trailer on 3 tires? Boy I would be changing my pants. Did it drive okay?...

I haven't seen any actual temperature values though when one should begin to be concerned about a potential problem. I realize that ambient and roadway surfaces are contributors to temperature increases, as well as brake usage, but I've only seen vague recommendations, like "Stop and let them cool when they get too hot". What is "Too Hot"???? 125 or 150 or 175 degrees or ??
To date, I compare the trailer temperature readings to those of the TV readings, and if similar, just assume everything is going ok.

So, does anyone have any actual recommended safe(?) operating temperature range values for tires and bearings?

Thanks,

Tom
Retired Over the road truck driver ran recaps on trailers in summer over I-10 L.a to el paso. stayed at the speed limit, stopped every 2-3 hrs and put hand on tire if unbearable check inflation and bearings. even 10 psi air pressure will heat those tires. Good question Rick

I'm thinking he took it in TV without TT attached. But I was curious also.

Any recommendations on a hand held thermometer to take these readings with?

Yes you can travel a short distance on three tires. Dual axels are designed to allow it. I have been to the big time tow company (near me) and asked, after a family member told me that a tow company towed his 5r to the repair shop without lifting it or doing a on site repair. The tow company confirmed that spring axels need to be chained up but both (type axels) are (if the damage is not to extensive) towed the same way. You do increase the chance of damaging the "single tire" by excessive weight so don't try to go to far. I traveled about 20 miles and did not damage the single tire. At the very least it will allow you to get off the highway. And, yes my cousin was fuming about having to pay his tow bill.

Sorry, It did drive good but I kept the flashers on and speed below 40mph. Got a funny look from a cop that passed me. I just shook my head to let him know I knew it. Don't know if he took an exit and came around again but I hit the next exit for repairs anyway. Whew....
