I am running an E rated tire and can run them up too max when I am loaded and I can run them down to the recommended pressure on my door placard 60 psi up front and 40 psi out back when unloaded.

I of course do not get a light at max pressure. When I air down to 40 psi in the rear, the warning light in the instrument cluster will light up. I then use the light load switch and all is well lol
