What pressures are you guys running on the stock tires for aggressive canyon drives? I could use a little help dialing in my pressures. I'm on the Conti's BTW, but will be moving to M4PSs shortly. Thanks.

For track driving I run 38 front and 36 rear when hot. The front biased pressure makes the car more neutral on track.

I have been using 35 all around as recommended by BMW.

well for last weekend's 20 mile brief wake-up from winter hibernation, i ran 27lbs all around on my stock Conti's per the car's TPMS. it flashed a warning not to drive over 80 mph. I then checked with my own gauge and they showed 31lbs all around. Pulled into a gas station and their gauge showed about the same...31lbs. Curious as to how accurate the reading from the TPMS is. Sorry for the slightly off topic reply.

TPMS reading are usually low. My readings are constantly 2 pounds lower than my calibrated tire gage.

Precisely what I found out as well on my TPMS - 2 psi lower. However, no way of confirming how accurate tire temp is. I guess use it as a baseline to see how much it increases on track.
