Winter vs Summer tire pressure
Noticed when putting on winter wheels and tires and setting up TPMS that there are different options for summer and winter. Summer is 29/30 front/rear and winter is 32/32.
I am primarily interested in dry performance so should I leave it at 29/30? Is 32/32 to get the tire to press harder on snow and ice?

Winter tires tend to be softer compounds and have a lot more flex. Running a bit more pressure helps improve the handling performance. Kind of opposite of summer tires.

I have 991.2 gt3. I'm wondering what you think about front TPMS vs rear in summer and winter. Right now in Feb I'm at 28 front and 32 rear once I've been driving for about 15-20 minutes. What's the ideal numbers to be happy with?

Besides the flex vs. performance, high pressures also help softer winter tires avoid pothole damage and maintain their load ratings. No way to know which issue is the main driver for the increased pressure rating, or if it’s some combination of all three.
