Hi folks, I drove 200 miles today in a hot-humid day. Temps were 85-95. I noticed that the temp of the dually tires on the passenger side were running 10-20 degrees hotter than in the driver's side. The passenger side is where the fridge and combo washer/dryer are located. The temp on the passenger side were 124-135, The ones on the driver's side were 110-120. Is this ok? Or should I be concerned? This is my first MH, there is a lot I don't know.
My TPMS system has the hi temp default warning set at 158* F and they recommend you don't change it; they say that "is the Michelin standard". Also, quoting the user's manual: "........ tires typically fail between 180-200* Farenheit". Hope that data helps you "fill in a blank data point".
FWIW: My passenger side (inside) dual is the hottest running tire on my rig....... often at 135* or so. A truck tire shop mgr told me that inside duals always run hotter and he said it is generally thought to be due to poor air circulation in that position. Each of the 3 owners of my rig has had one blowout ..... each time an inside dual. In my case it was on the driver's side and the TPMS gave no warning of overpressure, underpressure or overtemp and the tire (Goodrich) was just a few months over 5 yrs old. Happened on the way home from CA after purchase; so I bought a set of 6 Bridgestones in Las Vegas. I have since put over 15K miles on the rig (about 3K miles in the desert SW ..... at 115* part of the time) without tire trouble of any kind. Still, those Bridgestones will never see a 5th birthday on my rig. (I belong to the "tires is cheaper'n bones" club)
Pretty common knowledge that just about all 30+ ft Class C's are loaded to the hilt, so to speak. I got CAT scale weights for mine early on (loaded as I usually travel) and, like you, I am well under my GVWR and my GAWR's too (need to get "4-corner" weights someday)..... carrying heavy/dense stuff in the toad helps keep the MH weights in check. I believe the 16" tires are the weakest link in the chassis on my coach. Much as I enjoy my rig, the big ol' wheels and tires the Class A's have are a real advantage IMHO.
