Default Tires, how low can I go?

I have a new set of Barum Bravuris 3HM tires on my 2002 SC430. I believe the standard pressure is supposed to be 36 PSI but the roads around here are not too good, and I get a lot of shudder on some of the local arterials. How low can I set the pressure on these tires without either damaging them, creating other problems, or engaging the TPM system.?

The spec on the run-flat is 33, I don’t know what’s for the regular but I suspect it’s 35. Others can chime in.

33 psi is the recommended air pressure. Keep it that way. 36 is too high.

if you look inside the driver's doorway, you will see a sticker that has the tire pressure recommendations.
