Recommended tire pressure WTF
After some (very little) experimentation, I’ve decided that the recommended (stickered) pressures suck (are very much not to my liking).
My ‘19 rwd lists 38-45 (front-rear) on the door.
I’m running stock-sized non-run-flat Michelin 4S.
My opinion is that the car feels very unsettled, darty, and nervous, with zero on-center feel at these settings. This inspires me to feel the exact same way … plus sad about how crappy it feels.
Just now I tried 34-36 and was quite impressed.
• The steering was heavier and deliberate.
• The ride was noticeably more comfortable, steady, and confidence inspiring.
Everything about this was better from a seat of the pants perspective.
I may actually add a couple of pounds and see how that is.
But, generally, is BMW recommending only for better mpg?
Or am I somehow destroying my car or tires as I make it much better (IMO) to drive by setting significantly (percentage-wise) lower-than-recommended pressures?
Also, the in-car monitor differs from my hand-held gauge by about 3 pounds. Is that normal? Yes, I’ll check with another gauge, but am curious if that’s a common condition.
