Tire Inflation Charts
Yesterday on the way home, I stopped at the scales. In round numbers, the front weighed 3,800 lbs. and the rear (dual) was 6,900 lbs. I was able to get both axles on the scale, so the front and rear d...

Hi,
Because you did not get side to side weights, consider this. One side of your RV might be say 300 pounds more than the other side. You could have a significant difference in front tire load weights. This is especially true for RV's with a slide out on the drivers side, front, they can typically be at the max tire weight rating on that one tire, while others are less than the max weight.
So I would keep running 65 PSI front, and can go down a bit on the rear tires, just making sure that they will not rub against each other in the back. Check the lower portion while on pavement, see how much space is left back there.
RUnning the max tire pressure of 80 PSI will cause it to ride like a lumber wagon, so deflating a small amount can cause the tires to absorb much more vibration, instead of transmitting it to the frame and passengers!
Good luck,
Fred.
