Door Jam PSI different than yours??

joepa150 · 12-14-2013, 08:10 AM

I just bought a 08 328i sedan with sport package. It has 17" wheels on it. I don't recall the tire size but the rear are wider than the front.

TPM shows green on all tires but I figured I check them anyway. The front tires were around 32psi and the rear were around 31psi. I bumped them all to 33 psi.

My door jam says 32 psi for front and rear. It also said something like if you go over 100mph, to increase psi to something higher (I can't remember what).

I searched some threads and it seems that most show different psi on front than rear according to door jam??

BMW seems to have revised the recommended tire pressure in some cases as the model years went on for the e90. For example, my 06 325i with sports package door says 29F/32R. But some of the subsequent model years said 32F/35R or 32F/32R. I found 32/35 to work great for my purposes. Sizes are: 225/45R17 front and 255/40R17 rear.
