Tire Pressures

My Corsas are worn out, so I am replacing them with PS2s (almost got Advan Sports but that's another story). For those of you running other tires, what pressures are you running?

My understanding was the extreme high pressures recommended on the BS were only because of the Corsas, so I assume I can lower them a few pounds...

What extreme high pressure are you referring to? Factory recommended pressure for the street is 38f and 33r. The higher pressures (48f, 44r) were for speeds in excess of 155mph.

I agree with you on the factory pressures, but the issue was that a lot here on the board seemed to think that the 38f and 33r were not very good with the Corsas, even for everyday driving. I noticed this when turning the wheels going slow, the fronts almost looked flat at any PSI less than ~44.

I got my PS2s installed on Saturday and am currently running 40f/36r. I am going to try a few different variations over the next few weeks and see how it feels.

I think one question relating to lowered pressures is rim damage. I have gone to lower street pressures on Bridgestones, but have had to send out 3 rims for straightening (i about 37,000 miles). AS

That doesn't sound like a good trade-off.
