Yet another tire pressure question.
I could use some verification of the tire pressures for my motorhome. I think I have this right, but I sure would like someone who knows more to confirm if I do. My coach is a 2002 Monaco Diplomat...

Vonkal, if you want to run 100/110 that's up to you...it's your coach. You may find your coach to be light on the front as far as steering goes and a little squirrelly in the rear due to over inflation. You could always do the flour test if you're unsure.
First question is whether your coach was camping ready when you weighed it? You mention full fuel and water. That's good, as most of us only travel with 1/2 tank/water or less unless we're boondocking. Water weighs 8#/gal so removing 50 gallons of water give you 400# of "stuff" to carry, usually groceries without changing the dynamics of your weight. That said, once you load your coach with your camping goodies your weights may change due to how and where you store your stuff. This is why I add 5# to the recommended weight charts.
IMHO, load your coach for camping, full fuel, then weigh. Consult the Goodyear chart for proper PSI, add 5# for moving stuff around and you're set.
Finally, get yourself a good TPMS and install it. We use the TST 507, external sensors replaceable batteries. Besides PSI it also shows the tire temp. A locked or hanging caliper or bad bearing can overheat a tire to the point of catching fire. The temp portion of the TMPS can alert you well before that point is reached.
Good luck....I know a lot of this stuff is confusing as many people have opinions as to what is best. I tend to follow the recommendations of the engineers that work with the mfgs of the tires. Afterall they are the ones that have the knowledge and have done the testing to provide us with the best information.....Dennis
