While this subject has dominated just about every RV Users Forum, it never hurts to remind every RV'r that tire manufactures post their pressure/load charts on their websites. This information is critical to protect the side wall integrity from the very first rotation (cold temperature) through the very last at the tires' maximum speed rating. (Unless you have a dragging break, bad bearings or axle issue, the tires are manufactured to account for the increased temperature from road friction. BTW, I sincerely hope that every RV'r places the back of their hand on every axle's grease cap at every stop along the way. If it "burns", as opposed to being warm, you have a problem.) Going below the cold pressure for your weight, or above the speed rating for your few minutes of early arrival, puts not only you and your loved ones at great risk, but places those driving anywhere near you in jeopardy. On the G614s, there is 200 lbs per tire difference between 100 psi and 110 psi - that's 800 lbs difference for the 4 tires! ( https://www.goodyearrvtires.com/pdfs/rv_inflation.pdf ) On the Sailun S637s, there is 220 lbs per tire difference between 100 psi and 110 psi - that's 880 lbs difference for the 4 tires! ( https://fifthwheelst.com/documents/C...T-Modified.pdf ) Know the weight of your loaded RV and its axle weights is prominent on every RV Forum for this very reason. It only takes a few minutes and some very simple keyword searches for all of us to familiarize ourselves with the essentials of RV safety. If your home state/province does not require a special driver's license or endorsement for the weight of your unit, I'd still recommend that you search out the training guide that they use for those that do. Some very valuable information can be found within. Here's a good example - https://www.icbc.com/driver-licensin...full-guide.pdf
