I think I currently have 32 psi in all 4 tires. they are new and just installed. when I went for my first real drive to dmv, I can feel big slop in the rear handling/tracking. I may have some suspension tweaking to do, and car has not had an alignment, but I think 32 psi is far from being enough.
what do you guys think???? this is me pushing car side to side, showing tire sidewall movement.

What is the recommended tire pressure spec molded into the tire say? Radial tires have fairly flexible side walls so a flex like that is probably normal. I wouldn't go above the max inflation pressure for the tire.
looks like 51 psi is max. so I could try 40 psi and see if that helps. Dunlop sp sport 5000.

Lots of variables like tire type and width. I run 35psi of nitrogen in 225/50/16 & 245/50/16. Nitrogen is more heat stable and is a large molecule so tends to leak less then standard air.
