I’ve set them per the door sticker which seems sort of high and the TPS tells me they are +15 psi too high which one is right.

in the PCM there are settings for different tire and load setups, mine was set to winter tires heavy load even though the car was delivered in May on summers. After resetting that the numbers made more sense, 33/38 front rear or something like that.

Silly question - how can you tell if you have summer or winter tires, which affects which to select in the PCM. I’m in Texas and I took delivery of my T in North Carolina in May.

@Patriot - a winter tire will usually be narrower than a summer tire, the rubber mix is softer and the tread pattern will be quite different with more "pattern" and grooves to gain traction in snow and ice. Probably not neccessary in Texas :-)

I don’t believe any 911 will be delivered with winter tires, so you should be good. If you still want to check then you need to look at the tire to get the manufacturer and model of tire and then just check on the internet for what type of tire you have

you can look up your tire on tire rack.com
