Winnebago suggests 70 psi for my front tires and 75 psi for the dual tires in the rear. The tire company has the fronts rated at 110 and the rears at 90. Which is the right way to air the rig up?
Neither in my opinion and since Winnebago didn't weigh your coach fully loaded with passengers and ready for the road. The tire manufacturer didn't do so either and are only stating max withstanding pressures without any consideration given to actual weight or the wheel's rating, so pumping up to 110psi on an older wheel that's only rated for 90psi, isn't a good idea either. I've never heard of a wheel exploding under pressure, whether old, damaged and rusty or not, but if it was to happen, then one should probably be cremated or have a closed casket for the services.
Anyway, weigh the coach axles individually and add a 10-15psi cushion over what's listed on the inflation chart for the many variables that one will encounter on any road trip.
