Higher Tire Pressure

But then the sidewalls deflect and the cornering suffers. I have my test corners locally, not to mention the commute, and the 42psi gives the best cornering for me/the roads/tires/etc. I kid you not!
Acceleration "grip?" Not interested - not in THIS car....

Not trying to save pennies at the pump. Trying to enjoy the drive
We each have a different definition of "enjoy" when it comes to driving.

Good point. Sorta. I see your point. But sidewall is going to flex as bad as w/e, with max psi, or lower psi.

Sidewall flex def drops with higher pressure. Take it to extremes, and look at a nearly-flat tire compared to a well-pumped tire. I realise this isn't totally fair, and that the difference between a HIGH-pressure tire and a normal-pessure tire is significantly less than the example.

Nah, I'm agreeing with you. I was just saying it'll still flex. But you're right, i'll bow out more with less air.
