Just swapped out OEM 17" wheels on my 2012 528I Xdrive to 351 M Sport 245/40/19 tires and wheels (non staggered). I know I can look at the suggested pressures near the door but since this was a modification, wondering what pressures you would recommend for the new tires?

look at the stickey at the top of the menu. Have fun with those rims, i hope you like them. Just a tip, by the way, if youncould buy non runflats for your car after the current ones wear out.

Good luck OP😊

Thanks but the sticky above does not mention tire pressure on the 245/40/19's. Why the recs against run flats? Not sure I really want to carry a spare in the trunk and just went 35,000 on my prior run flats?

It will significantly improve the ride quality of the car as well as the handling ability. There's a reason why the M5 doesn't come with RFTs. Sorry about the misinformation before.

Good luck!

35psi would be a good starting point.
