Its yust what you want, fuelsaving or comfort and gripp.
I am able to calculate a safe lowest pressure for the weight and speed , and that gives max gripp and comfort. Probably that will come in that 30 psi aria.
But also can calculate max pressure, with acceptable comfort and gripp .
A bit above that you get centre- wear.
For electric cars like Tesla ,as high as 42 psi is adviced by carmaker, all to give the battery a larger actiradius. The lowest safe pressure would probably calculate as 30 psi, and on those fora centrewear is mentioned often.so give weights o axles, and more tire- specifications. Only need to know if XL/ reinforced/extraload or not, the rest I can google.
The carmaker nowadays use the GAWR's as weight to calc the pressure for, for max technical car speed, or often gives 35 psi ( referencepressure of standardload tire, eur 36psi) as general advice .
Referencepresure of XL// is 41 psi ( eur 42 psi)
