New tire and wheel size, what pressures to use?

Hi all,

I just switched the wheels on my GT from the stock 19x9 255/40/19 Pirelli Pzero to 19x9.5 275/35/19 Michelin Pilot Super Sport.

The cold street pressures on my door label say 35 psi.

Anyone have an idea what my new street tires pressures should be? The guys at the tire shop said "32"... because I think they set all cars to 32 :)
 
I have PSS for the street and set them to 35. Not sure if that's the best but I stuck with the stock pressures.

How do you like them compared to the Pirelli's?
 
Thanks for the info, guys.

Honestly, I only drove them once and I couldn't tell much a difference, though I was babying them because the tire dude told me to "not go hot-rodding around until the tire grease evaporated off after 24 hours".

I'm sure *hoping* I can tell the difference. I'll report back soon.
