Switched to not-runflat, tire pressure question

The tire pressure recommendations on the car B-pillat sticker says 32 in front and 39 in rear. I switched to regular tires (i.e. not runflats) yesterday. For those that switched to not-runflats, did you keep the same tire pressures as when you ran runflats?

keep them pretty much the same. I run mine at 34 front and 36 back, because I thought the fronts were too squishy at 32

What tire size? I run my front 225/35/19 at 43 psi and the rear 255/30/19 at 48psi. For the E92 that's around 2-3% more of what is specified by the tire manufacturer (Fulda).

BTW the car drives so much better without that runflat crap. I highly recommend switching to non-rft if one can pass on the extra safety in case of a flat.

Can I ask what tires you're running?

I was using Hankook Ventus 12s on the 330xi that I just sold. My 2011 335i (sport) has Continental run-flats on it that are in pretty good shape but won't last until inspection next April.

When I test-drove a different 335i at a BMW dealer, I mentioned how I hated the run-flats that came with my car when new (the '06). He said they're much better now than they used to be and last much longer, but I'm skeptical. They're also very expensive while the Hankooks were about $500 installed.

Recommendations for OEM 19s (on RFT) is somewhere around 42 front and 46 rear, I'm running around 34-36 all around.

Seriously? 42-46 is pretty high for cold temperature... Some tires max out not much more than that...

I am running the factory 225/40/18 in front and 255/35/18 in the rear. Agree the car drives sooo much better with the non-rft.

I only have 24K miles on my car and the factory rft were in good shape. But last weekend I went to MA to visit my daughter in College. On the way back a hit a pothole and the rtf outer rubber cracked and separated from the inner tube. The inner tube was totally exposed. I drove home carefully and immediately order a set of tires from tirerack.

Don't do it. See my prior post. I drive a 2013. I had the factory Michelin and they cracked after hitting a pothole.

many, including myself, have settled on about 3 psi higher than what is stated on the door sill.

I'm on the standard 18" tire sizes, same as you aside from that. Are you running the psi on your sidewalls? That is the rated maximum, not the recommended. Just wondering why you're psi is so high, maybe its different for 19" wheels.

XDrive square setup with Michelin AS3 and usually always have them at 38psi. Though last week I set them to 36psi. No noticeable difference in MPG but a slightly softer ride on the bumps. Door jam says 32psi.

48 psi is way too high... Max inflation is probably around 51 psi. That'd dangerous IMO.
