RE: Michelin Load & Inflation Tables
The total weight of the coach is not meaningful for this discussion, only the axle weights. It is *extremely* unlikely that any 80s or 90s WB needs heavier tires on the drive axle, so why fight the spacing issue? The 295 is smaller in diameter than the 315, which in turn is smaller in diameter than the 12R; the 295 varies from tire to tire, but generally about an inch less in diameter than the 12R.
The big issue is purely the steer axle. What do you weigh there? Many Birds, including my previous and current ones, are at or over 14K on the front axle, which is where the 315 really, really, helps. I changed Blue Thunder to 315s on the steer, and Chuck changed all of the ones on this one to 315s. I don't plan to run spacers, just greater pressure to maintain separation until it is time to replace the tires again. Don Bradner 2004 M380 Double Slide 1990 WB "Blue Thunder" Sold My Location |
