I'm running 16 inch steel trailer wheels with 7.50x16 tires at 50 psi. The wheel will carry it's max load at whatever the tire pressure rating is. The air will strengthen the tire, but not the wheel. Above the max rating (the 110psi) you are over stressing the bead of the rim and courting failure.


Current fleet (subject to change w/o notice)
\'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run.
My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
