Tire Inflation Guide
Can anyone tell me where I can find a chart telling what pressure I should run for the axle weights that I have? Thanks

Need to look at the load range on the replacement tires. Most RV replacement tires are one or two load ranges high with a higher max. pressure then what was originally put on. I was taught many moons ago that to be safe air tires to 10% of what the max. pressure is on the tire. This has worked for 40 years now.
Well, I'll admit I've never done that, I've alway's aired to max sidewall rated psi...never added an extra 10% which would be loading a Michelin "E" rated RIBS to 88# instead of 80 and airing my GY G614's to 121 psi instead of the recommended 110psi...one could do that, but again, I've been towing since 75, (and some before that), and also never had an issue... and thats worked for me for almost 40 years also...
My experience has seen most newer RV's with tires on them that are "just close" enough to cover axle rating...as little as the manufacturer can get away with and cut corners on cost. It's rare that I've seen a "G" rated tire where an "E" rated tire would have worked...it's very, very rare.
