please tell me what pressures you keep in your SL65 original bridgestone potenzas.

and do you find your tire pressure monitors work reliably?

thanks.

I assume you know the best place to start is the pressure listed on the fuel filler flap.

The TPMS tends to be very accurate -- more accurate than any tire gauge. It was a bit of a shock that even my expensive dial gauge reads a couple of PSI low. This is common.

just wondering if anyone varies the pressures from those specifications at the fuel filler and driver's door jamb.
