OK, guys. I took your advice. I'm going to get individual wheel weights as soon as I can get them.
In the meantime, axle weights will have to do, AND I have yet another question relative to my tire manufacturer's inflation table and what my tag and drive axles currently weigh. Still makes no sense to me.
So here goes...
Drive axle (duals) weighs in at 14,680 lbs. Tag (singles) at 7,340 lbs. Steer axle at 13,460 lbs. So far, so good. The air ride on my diesel pusher is dividing the expected 2/3 of the rear weight to the drive axle and 1/3 on the tag. Cool.
Now, on the Bridgestone R250F 295/80R22.5 inflation table for singles, the actual weight that's on my tag tires (7340/2 = 3670 lbs on each tire), that pressure doesn't even show up on the table (minimum = 5350 at 80 PSI). Does that mean I should run at 80 PSI? Is that even good for the sidewalls of these heavy tires to run that low? And why isn't there even a number CLOSE to the weight I'm actually running per tire? This coach is already pretty fully loaded for an extended trip (lots of clothes, appliances, other "stuff", full water, although only half fuel, empty gray/black tanks).
Same or more confusion on the tag tires.
At 14,680 lbs on that axle, divided by 4 gives me the same weight bearing per tire (3,680 lbs). Huh? At max pressure for max load for these tires (125 PSI), the MAX weight rating is 3,150 lbs. Now I KNOW I'm NOT overloaded, AND I still have to add another 1,000 to 1,500 lbs of trailer tongue weight to these two axles (six tires) once I get my trailer back, loaded up and weighed (and yes, corner weights ASAP). UNTIL THEN...
What the heck is the deal here?
My actual tag axle
weights are WAY BELOW THE MINIMUM
RATING on the inflation table (singles line) and WAY ABOVE THE MAXIMUM
rating for the drive axle
(duals line) on the inflation table.
I'm currently running 105 PSI on the steer axle
, which syncs with the table (13,460 lbs/2 = 6,730 lbs per tire = 100-105 PSI per table - cool), but can't figure out this drive/tag axle crap! I'm currently running 85 PSI on tag and drive axles, but that's with no trailer and what the previous owner ran at. I have no placard in the coach and I am NOT to just go with the basic generic manufacturer's recommendation at any rate as I'm not the average user. And I'd like to get this at least close to better PSI's before I hook up the trailer... HELP!!!!
Thanks in advance! And yes, corner weights are coming, just not yet for a few hundred more miles. And no, I have no manufacturer's placard. Arghhhhh
