Yesterday I had my HTR Z II's(225/40/18) mounted on the HM2's(18x8.5)and also had the H&R Sport Springs installed(328Ci). With this rim and tire, what is the best/correct air presure I should be running front and rear?<p>Thanks again Eddie, should have pics this week!

<p></i> You would still want to run the factory recommended air pressures for the car. The air pressure is based on the weight distibution and the handling characteristics of the car and not the size of the wheel and tire.

As for tire pressure, you should run off of BMW tire pressures, but I would suggest go by 17" recommended <b>cold</b>pressure for the 225/45R17s (32 f, 36r), and add +1 psi to compensate for larger 18" size.<p>You can fine tune to your tastes & driving habits.<p>Hope this helps. Wheres the picsKev???????????<p>See ya!<br><b>Eddie<br>800.428.8355, ext 369</b><p>Your official source of all E46 related info :-)
