Michelin Load & Inflation Tables

[DonB]

Your numbers are odd - it is not normal for the sum of the AWR to exceed the VWR, and yours do, dramatically (48300/44000). Your AWR for tag and drivers are both higher than expected.

In any case, I would do something about the actuals. Your tag suspension pressure should be increased, forcing weight to both tag and steer and off the drivers.

Later Wide-Bodies are much heavier, and the AWR on the steer is higher. Blue Thunder had a steer GAWR of 14300 as I recall, and the M380 has a GAWR of 14600 (some are upgraded to 16000). My actual weight on the steer this past Friday morning was 14,000 at an Oregon weigh station, with fuel down 50 gallons and the fuel tank is right behind the steer axle. Once you get into weights that high the 12R and 295 both have to be run with high pressure, leaving little room for error and a much harder ride. That is the incentive to move to the 315.
