New tires, lower MPG, should I increase inflation pressure?

ND (2022 Grand Touring). Recently replaced the OE Bridgestone Potenza S001 (Summer) with Michelin Pilot Sport AS4. I've always followed the MFR guidance of 29psi cold, which I watch pretty closely. I averaged 32.5mpg before, and 30.7 in the 3 tankfuls since. I'm not surprised that the all-season tires get lower MPG, but wondering if I should compensate with higher pressure?

Should I bump up the inflation pressure +2? +4? Pros and Cons please.

FWIW, I live in southern US (hot summers, mild winters, no snow, but when it rains it pours). This is my daily driver, not a track car at all. I switched to all season b/c I got a little fishtailing on wet surfaces with the Summer tread as it got to ~4/32". My daily commute includes places where I have to make a 90 degree right onto a highway, so I have to get on it a bit.

Thanks in advance!
