Tire Pressure

BMWE90 · 02-17-2008, 05:23 PM

I've just about had it with the tire pressure on my car. It's recommended that, at cold start, the pressures should be 33PSI front and 38 rear. Then everything would be fine for like a few days and the pressure would drop (but not enough to trigger the sensors). I just hate it because I have to do this like every week/2 weeks and it's driving me insane. The car handles like sh*t and the ride feels like crap. I've been meaning to take it to the dealer but have not found time to do so.

From what I've seen/heard, I'm pretty sure there's a slow leak in the valve stem somewhere. Thoughts anyone?

/End rant.

I had the same problem with my 2006 E-90. It was a leaky valve stem fixed under warranty.

depending on the outside temp, tire pressure will vary slightly. I say 1-5psi give or take.
