Tire Pressure for Pilot Sport A/S???
I'm getting my new Pilot Sport A/S tires today. They are a little bigger than the stock tires (225/50/17 vs. stock 215/50/17). While my Acura dealer says there's no problem with the size for the stock wheels, when I asked them about how much pressure they didn't know. I'm getting a good deal at Sears ($889.00 out the door) but I'm not sure I trust them about the psi. I kept my stocks at 33. Any suggestions?
, so I'm figuring mid 30's should be nice.

Michelin says 30 psi
Michelin says that because this tire handles a larger maximum load, if the stocks (215/50) are 32 psi, the 225/50 should be 30 psi.

Our car is "lighter" on these tires
No, not the way I understand it. These tires can handle more weight than the stocks, so we need to lower psi in order to compensate. Otherwise we don't have enough tread on the road. So if you kept your stocks at 32-34 psi, the 225/50 should be at 30-32 psi.
Another way of looking at it is that our car is actually "lighter" on these tires because they have a higher load capacity.
What do you prefer? Better mileage and poorer performance? Understand that the "equivalent" psi is lower, but the "effective" psi is the same. The idea is to have the same amount of tread on the road that you would have with the stock size- not more, not less, but the same. If you use the same or higher psi that you used for the stocks, which have a lower vehicle weight capacity, you will end up with less tread on the road and a higher "equivalent" psi pressure. In other words, if you used to run your stock 215/50 at 33 psi and you inflate your 225/50 pilot a/s to 35, you are actually running your pilots at the equivalent of 37 psi.
The folks at Michelin were very good at explaining this. You can call them at 800-847-3435.
