AUDIIOS

Posting this here because I have a Q5, but would likely apply to anyone with the new TPMS (based on wheel RPMS) not the old one (based on actual tire pressure). My TPMS warning went off over the weekend. First time since I bought the car in November. So I let the tires cool overnight and checked the pressure. They were all very close to 31.5psi. Low, I know -- but if they were all the same how did the TPMS monitor trip? Do they not just check one against another?

Separately, what's the max psi anyone would recommend? I'm looking to maximize MPG, and tire life. I don't carry heavy loads (no more than 450 lbs total) and I never go off road. Roads here in AZ are probably the nicest in the country, IMO. I have Continentals, 19" wheels.

Refer to your Owner's Manual for both Normal load and MAX load conditions. This info is only shown in the Owner's Manual.

Reset your TPMS when the tires are properly inflated and cool.

I have had great luck over the years with 2psi over the mfr recommended for normal driving. But monitor the tires every six months.
