Default Tire pressure?

Quick question--what is best pressure for highway driving for '13 911S with 245/305 Pirelli's? Sorry, too lazy to search...

Not sure if it's "best", but I run 32/36 F/R cold and have perfectly even tread wear.

So someone else should save your snowflake fingers from typing and do it for you?

31/34 for you. I like to run about 33/36 or 34/38 myself, though...

How fast are you driving? Maybe you ought to set them at 36/44, just a thought. You might prefer the ride...

Yes I'm a lazy slob... this is just one of those things I figured the learned would know off the top of their heads.
BTW since I live in the wilds of West Texas I usually cruise at 82-85 and occasionally blast it up to 110-120. Wide open Interstate with speed limits of 75-85, a V1 and (usually) understanding LEO's=making good time 😎...

Agreed that's pretty lazy... but that said just let your car do the work for you.

Pull up the tire pressure display using the right stalk, unselect Full Load, select Comfort or not (depending upon your personal preferences and driving style), then select the Fill Pressures display. It will tell you how many PSI to add or subtract based upon the current temperature of the tire and your selections as plus or minus PSI readings. It really couldn't be easier and you don't have to think about whether your tires are hot or cold when you do it.... it compensates for that.

Hope we don't have to come over and fill them for you?

I run cold 32 front & 36 rears. I have 20" 245 up front and 305 in the rear.

The pressures in the owner's manual are spot on. 31/34 comfort mode, 31/39 normal, 36/44 fully loaded. I typically run 31/38.

He just likes to turn left more than right (tracking?). Maybe he's a retired Nascar driver? Maybe he's really the Stig?!
