What sort of air pressure are you using for our rainy BA roads?

I'm curious to know how much air pressure you guys use in your tires during the rainy time on bay area roads (AK: Cracked, riddled with pot holes, improper camber).

Also, if you respond please state what kind of tires you're using, from brand to size. I don't care about wheels, just tires.

Some people recommend changing air pressure for rain, and others say it doesn't make a difference at all. What do you guys say?

...hmmm I wonder what I'm missing here. I run the factory spec of 32 front/29 rear. Am I missing something by running that low?

I have ContiContact extremes & LOVE them in the rain & snow. Not so great in dry though.

Are those factory specs like on your door jamb... for the stock tires?

Or specs for those particular tires?

I run a bit higher than most because I drive canyons every day and I drive a lot (better gas mileage).

When I head up to the snow I'm down between 32 and 35.

I generally keep 35psi all around. Right now I'm on Pirelli Pzero Nero M+S, but I plan to keep the same tire pressure when I switch to summer rubber after the snowboard season is over.

I've also kept the same tire pressure w/o any problems in the rain when I had the '07 Civic Si with Michellin Pilot Exalto PE2 summer tires.

when i used to have lots of fun in the rain in parking lots and such back in the day, i'd inflate to max pressure to haev as little contact surface to the ground as possible

I set mine 4-5 psi higher. This can help with surface area and less hydroplaining
Low tire psi can cause more contact patch and more tire surface to float on the top of water.
