I just noticed on my 991.2 that it's 35/45? Seems like a big gap and a high? Is anyone keeping them closer to reduce understeer?

And has anyone gotten a flat? Do you have to replace both rears? This was the case on my turbo s.

Check your manual for Comfort/Partial Load tire pressure.

Explained pretty well in this article as well. https://www.edmunds.com/porsche/911/...-pressure.html

Thanks I'll play with them a bit. I came home to fiddle with my tire pressures and I found a freakin nail. Now I have to take the wheel in tomorrow, hopefully they have a new tire.

Most everyone uses comfort setting. Car both rides and handles better.

I run 30F/65R. Gives it that old school tail happy feel.

JK. Like most others 31/34 but I'm starting to play with it pound by pound for AX.

Thanks for linking that. Very informative article.....except the part where my non-PASM car should not be rolling on 20's

I'm running +1 above comfort pressures all around.

I run higher than most here.

I like 36/40 in the cooler spring (March and April) and fall (October) months and 35/38 in the summer (May-September) months. That was on my PZeros for 37,000 miles (2 sets of rears, one set of fronts). I haven't dialed in the new Michelin PSS yet. I will next driving season.

Been running the PSS for w while now. Running 32/36 and getting even wear across the entire width. Rears being replaced this week with 11K miles.

Ran my first set of PZeros to 15,000 miles. The second set I ran to 21,000 miles. I expect the same from the MPSS.

^^^. Good luck with that
