In another thread it was recommended to use the weight/inflation chart and add 5psi to the pressure recommended. I've seen this before, but never understood why. Can someone explain the need for an extra 5psi?
I had my first motor home weighed on four corners and was given the GY weight/inflation chart and told to add 5psi to 10psi to the pressure recommended. I did that and got pushed all over the road by trucks and mother nature. When I bought my second motor home I again had all four corners weighed. I followed the weight/inflation chart for Michelin and didn't add anything extra. What a difference! I don't get pushed around by trucks anymore. I only know they are there because I see them coming up in my mirrors. It's made a huge difference in the ride. Mother nature on the other hand still has her way with me.

I have never see a chart recommending to increase PSI by 5 or 10 lbs and have no idea why that would be a recommendation. If you have Michelin tires I would follow their chart, I do.

Different MS and different tires are the reason for the different handling NOT 5PSI!

I would agree with you except I had poor handling when I bought the rig. After I had it weighed and adjusted the tire pressure to what the Michelin chart recommended, the handling became much better. The dealer or previous owner had set the tires to about 10 psi over what the chart recommended.

Didn't mean to mislead you. The recommendation didn't come from a chart but from several people, and that got me to wondering why.
