The 82 is the inflation recommended by the RV mfg based on the estimate for what stuff you will actually be carrying. The only way to know the proper cold inflation is to check the actual load on each tire, look up the required minimum inflation needed and I suggest you run at least 10% more psi but not exceed the infl on the tires on the motorhome. I have a number of posts on load and inflation calculations.Tireman9https://www.blogger.com/profile/09813984937064446653noreply@blogger.comtag:blogger.com,1999:blog-4197373783392349499.post-35408080051854826442014-04-05T06:40:55.328-07:002014-04-05T06:40:55.328-07:00i read all this info on tire air pressure. my rv h...i read all this info on tire air pressure. my rv has a placard at the drivers side that read as follows: 2948 front, 4990 rear, 245-70/19.5G, 133/132L, 82PSI. if i am reading the tire chart correctly, it seems with this weight i should use 95PSI?? when i have inflated to 95PSI and have had my dealer check to insure no leakage, the dealer reduces the tires to 82PSI stating due to the placard that is all that can air to. PLEASE explain the charts. my tires are goodyear G670.Anonymousnoreply@blogger.com
