Hi all,
Have a question about tires..Tires are hot at 80, 82 psi returning from cold mountain trip thru local desert, traffic and home. Rear tires noticably hotter than fronts and had a smell like hot rubber.
Posted are the weights on the axels for my 23u thor. I notice I'm about 700lbs below the limit of the rear axle. Usually that axle is loaded about 600 lbs lighter. No smell, not so hot.

Is there a danger? Factory michelin tires, 2016 date. Don't recall smelling this. Tires not painful hot but hot. Touched the rims, axle shafts..not the source of heat. It's tire flex. This is the most I've loaded this. E450 chassis, 2017 model 14,000 gvwr. Usually carry a 300 lbs motorcycle on back never a worry. This time a 470 lbs bike and about another 50lbs lbs for the more stout rack tying into frame.

Any thoughts?


Thanks
