You seem to be confident about this payload/PSI relationship for each and every tire. May I ask where you're getting this info?
A little common sense and 50 years of experience.
And it is not "for each and every tire".
It is only for going UP one load range rating without a significant increase in load.
Other considerations may apply if making more drastic changes.
Common sense, experience, and the ability to appreciate "other considerations" varies widely from individual to individual. Assumptions can be deadly.
BTW, your comment "only going UP one load range without a significant increase in load" ignores the fact that tire load and PSI are NOT linear from tire to tire. Specifically, how do you address this non-linearity?
