I did consult my manuel, door jam, and even spoke with BMWNA a few months back. They didn't have a straight answer for me, and I settled on 30F/35R (I have a 545 w/ sport). They the shop forman said that was low and did tell me about some cases of premature tread wear on the inside of tires...Now I'm at 35F/38R-too soon to give my input on ride quality, performance, and milage...

Sorry about the format here, but it's not WYSIWG so I can't get it all to line up.

[/quote]My sticker also says 36F/44R which I've been using with no problems for 6,000 miles now, although I do lose 2 - 3 lbs each month when I check, which is higher than I've experienced with other cars.

I went two or three months wo checking this time. I also had lost 2-3 pounds all around. FTM never peeped. Have not initialized FTM within the 400+ miles since I added the air. Still no peep from FTM. Now with a 6# differential between front and back, I sort of expected the OBC to complain somehow. I'll try to remember to initialize again this afternoon. Interesting, huh?

My Ride: 2005 545i born July 13, 2005, Jet Black with Black Dakota leather interior, 6 speed manual transmission, with sports package, premium sound package, cold weather package and satellite prep...persistence overcomes resistence!
the adding 6 psi w/o resetting the ftm does seem strange...i once had the ftm go off (04 530 w/o run flat tires) and SA said it had been overfilled and goes off when the pressure changes 4psi either direction...
thanks,
edl

[/quote]I think that if you want to maintain the highest integrity of the FTM, it would be prudent to initialize FTM after any change.
