Need a math teacher for tire pressure confirmation
I have weighed the coach, done the math and checked the Michelin pressure chart, but it doesn't seem right. Please confirm that I am correct or point out my error. Thanks.
Michelin 275/80R22.5 H XZA3 tires.
150 Gallons of Fuel
Fresh Water Full
Liquor cabinet Full
Steer axle: 12800#
Drive Axle: 15020#
Tag Axle: 7380#
When I check the Michelin chart, I get:
110 psi on Steer
75 psi on Drive
75 psi on Tag.
I know it is a big difference on load per tire from the front to the back, but it just seems like a big difference in pressure on front and rear.
PLEASE NO GUESSING. PLEASE NO OPINIONS. JUST PURE KNOWLEDGE.
