Tire/HUB Temperature Issues - I'm stumped
Background - I recently got a TST TPMS after replacing wheel bearings on all four wheels of my 2017 low-mileage 21RBS Cougar. I bought this trailer late in 2018.
On an initial test drive, I noted one wheel (back passenger side) temperature elevated about 20 degrees above the others at 95 degrees F. Confirmed it was hot to touch. I pulled the hub, bearings all ok but brake seemed to be dragging slightly. (I had adjusted all brakes during bearing replacement.) After backing the adjusting nut on the brake out a few turns, everything worked great on another test drive. All wheels the same, and about 5-6 degrees above ambient.
Current trip - After about 3 hours, the "other tire" on the passenger side starting increasing temperature above the average of the others (~80 degrees F) It got up to about 91 F, and was hotter to the touch compared to the others. I have backed of its brake adjuster a few clicks to see if that helps.
I have never had a TPMS before, so maybe I am watching it too closely. On the other hand, could the brakes be occasionally dragging after use during normal driving. I checked all of the springs and braking mechanism while apart and it looked fine.
Should I be worried, or just continue to monitor and let the brakes and bearings wear in for awhile? Really don't want to get back into the bearings unless I have to.
