Does anyone know what temperature range wheel bearings should be at during use after maybe 100 miles or so at 70 to 85 degree ambient temp? I will be measuring with an infrared heat detector at the exterior hub.
I'm looking for a range that is acceptable and temps that, above which, I should be concerned.

I'm not sure of a temperature range, what I look for is one wheel being hotter than the other ones.

This summer running in 100F temperatures in Utah, Arizona and New Mexico, my trailer hubs were in the 120F to 128F range, tires were in the 135F area.
My truck was, rears about 135F and the front hubs were. About 10 to 15 degrees warmer. Most of my checks were done at rest area or fuel stops, so the temps were related to and varied by how much I had used my brakes to get stopped. Rear duals are not easy to get a clear shot on the hub and not the brake calipers, etc.

This. Look for one wheel or tire that is way hotter than the others. I would guess the wheels and tires could be 20-35 degrees warmer than ambient air temperature most of the time depending on how, where and when you measure. This is based on the temps I saw on our 4,500 mile Co trip this summer. I measured temps at all fuel stops right after pulling in and before fueling.

Also, if you are checking your hubs after a hard stop you may be looking at brake heat rather than bearing heat. When I am checking the hubs I turn the trailer brakes off before I stop.
May not be a big deal but that's what I do.

You are really looking for a temp on one wheel far different than the others.

TST sets the alarm for tire air at 157 IIRC, the bearings would be something below this, maybe in the high 140's. We had a bearing failure on our summer trip on the @#!$ Dexter Nevrlube bearings and the temp jumped to almost 200 degrees.

Thanks everybody
This is all good info. I pick up our 5er tomorrow after a wheel bearing repack and brake job so I wanted to check on the return trip to verify that everything was OK.

I feel yer' pain about those "@#!$ Dexter Nevrlube bearings" ours went nova on the way home from Florida last spring and stranded us in a wrecker's yard for a week,thanks to Dexter's hal-azzed service,i'm replacing the other three this fall before we leave.

Keep in mind that the temps on the sunny side will be 15-20 degrees higher than on the shady side while you are traveling.
