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?
Go read your tire sidewall again.
It does NOT say "Inflate to 110psi"
What it does say is:
"Maximum load is xxxx# at a Maximum pressure of xxxpsi." (These are reduced for a dual configuration)
I suspect your Winnie is not loaded to the point where you are loading the tires to the maximum.
The numbers on the tire placard are what Winnebago considers appropriate for when your rig is loaded to its axle ratings.
Post 2001 or so I recall Winnie suggested increasing those by 5psi. That was CYA action followed by a LOT of Manufacturers after the Ford Explorer/Firestone debacle.
I suggest you use 75psi front and 80psi rear as a starting point. Those pressures are adequate for the loads you are running.
IF the rig feels a little squirmy, then by all means increase them a little until it feels better.
But running at 110psi and 90psi will probably result in a very harsh ride.
