30 psi pressure rise seems excessive. Has anyone put some type of "goop" in the tires attempting to fix a flat or balance them out? What does the air inside the tire smell like when you bleed the tires with excess pressure?
When I run my 19.5" G670's at 90 psi cold (18,000 lb. GVWR Ford F53 chassis) the pressure would go up less than 10 psi on a hot day. The actual weight of my RV was usually between 15,670 and 17,000 lbs. Running the tires at 80 psi put excessive wear on the outside edges of the tires so I raised it 10 psi. Under my driving conditions, Goodyear says its OK to do that. The coach manufacturers recommended pressure is 80 psi.
