But that really is one heck of difference between 80 psi and the max of 125 psi., as opposed to a max of 110 psi, and running pressure of 95 psi. The first would be a difference of 36 percent, versus 13 percent. Major difference. And it may have as much to do with the aspect ratio as anything else, with the shorter sidewall. I believe the 17.5" is a 215/75 versus the 16" 235/85.
Personally I would be uncomfortable running less than 90 psi on my "G" rated Sailun tires. But that's just me.
What does the load/inflation chart say? If it's listed there would be no concern.
