Ok ,

Just as Jon said about searching the correct words or phrase on the internet. I will try another route in asking a more specific question to the gurus. I know Jon previously owned a 40 XL Liberty coach. And Truk has owned some XL’s in the past. I know it has to do with the axle weight. As I stated in My original post. I just need to know roughly what pressures I should be running until I can get it weighed. I want to be SAFE as I can be to maximize My stopping ability. And take care of My new Michelins.

Jon , Do You remember what Your axle weights and tire pressures were on Your 40 XL Liberty with 315 tires and full of fresh water ? I bet You have a copy of the log book from every coach You have owned ?

Tom , Same Question on Your previous 40 XL’s ?

Or , If You were going to pick up a mid 90’s XL Liberty and drive it for a thousand miles and were unable to weigh it. What tire pressures would You run in it ?

Thanks in advance,

Safe travels,

Rocky

Take this with a grain of salt because a 40 foot coach has different rear overhang which impacts axle weights compared to a 45 foot. The reason I say that is I had 12.00 tires on the 40 and 315 on the 45.

Going by memory my 40 foot had 110 in the steer, 85 drive, 70 tag.

My 45 with 315, although 5000 pounds heavier had 105 steer, 90 drive 85 tag.

Those are going by memory and I have a severe case of CRS.

Three years ago, following Jon’s advice I fully loaded and weighed each axle of my 40′ XL and using the correct Michelin RV chart set mine at 105/95/90. This included Jon’s recommend 5psi safety margin.

Sat next to Michelin’s military ground tire executive at a meeting recently and he could not emphasize enough the permanent damage caused by driving under inflated tires even once.
