Coach Weight

OK. We had the coach weighed by smart weight. The left rear of the coach is 600lbs heavier then the right rear. Front of coach is within 50lbs. All my tools which are considerable are in the Joey bed and on the passenger side of the coach. Black and grey tanks were empty, water about 3/4, propane at 1/2 and we have no muffler just a straight pipe. Can't figure out why the drivers side rear is 600lbs heavier then the passenger. Only thing that comes to mind is the two 8D west cells, but six hundred pounds?

Roland those 8 D's run about a buck and a quarter each.

Have you checked ride height? If the left side is higher/right side is lower than spec, it can/will transfer weight to the left side.

When we weighed about four years ago at the Florida SEA rally we were 1000 lbs heavier on the driver's rear side. No explanation. In a hurry so didn't wait for the report just told them to mail it to us. Ride height is OK. Never have figured it out but 1000 lbs is a bunch. Front was within 100 lbs left to right.

At 600 to 1,000 pounds difference the tire pressure should reflect the actual load on that tire per the chart I would think.

Looked at the specific Michelin chart for my exact tires and weight without knowing left to right and I am about 2 high on the front and five on the rear at 90 rear and 100 front.

As I read the info from Michelin and virtually everyone else tire pressures should be uniform across each axle based on the highest load.  Seems like big differences from one side to the other is going to put a lot of excess stress on the axle and differential.

8Ds are about 165 lbs each.  They are tough to install.

Sorry, INCORRECT.

All tires on an axle should carry the SAME PSI BASED ON THE HEAVIER WHEEL POSITION.  Same recommendation from all tire manufacturers.
