Tire pressures - runflats vs. non-runflats?
At 3K miles I switched from original runflat tires to non-runflat Michelins. Are the original factory recommended tire pressures still applicable, or do the non-runflats call for different pressures?

I use 34psi f and 32psi r on my non run flats. I’m on Michelin PS4s. I started off at 38f/36r gradually lowering tire pressures as I drove. Took a few months on every setting and settled on the current tire pressures. I find it to be the best pressures based my driving style and comfort tolerance.

I'm running 40psi front and 38psi rear. Bone jarring ride, though it helps stop these weak as **** wheels from cracking
