I've been looking at other discussions regarding tire temperature and pressure during use, and I really didn't get a feel for what was normal and abnormal. So I'll give you my saga and if someone can please let me know if this is normal?
I'm still on my stock Cooper Work series tires, 215/75R17.5 RHT 2, load range H (and there are a whole bunch of other numbers I could grab) for my 2023 Solitude 310GK with 8K independent suspension. My tire pressures started at 125psi, the cold pressure stated on the side of the 310GK, and this was seen on both a manual tire gauge and the stock Lippert Tire Linc TPMS. Ambient started around 76F, and climbed to around 100F during a 2-hour drive in TX.
My temperatures/pressures according to the TPMS during the drive steadily increased such that by the time I got to the end of the 2-hour trip the hottest tire was 149F/150psi, and the preset alarm (just showed red) indicated at that temperature/pressure combination. I'm guessing that if the trip were longer it'd continue to go up, though temperatures and pressures only went up 4F and 2psi in the last half hour.
Haven't repacked/regreased the bearings since delivery, though that's happening in a few days, and some folks in other threads have mentioned that TPMS temperatures are from the rim, so could that be a function of axle temperature?
Weights are well within ratings: trailer GVWR = 18,000; scale trailer weight = 16,240, trailer axles weight = 12,840. I haven't had all four wheels individually weighed (e.g., at Escapees in Livingston, TX). I did notice more visible flex in the trailer rear wheels than in the front wheels (was more pronounced before I lowered the bed; I guess I could lower the hitch another inch), and the rear axle tires had higher pressure (by 5psi) and temperature (by 13F).
So is this sort of pressure difference, 25psi, during a drive normal?
