In the MCA mag it has been stressed numerous times that the tire inflation is
*absolutely* critical. They mentioned that the chronic wheel shimmy is affected
by the tire pressure and that the rubber won't "heat up" properly with higher
inflation than whatever was recommended (28psi?).

I have had Pirelli P500s on my car for about 15K miles. The recommended
inflation is 38PSI (which I maintain regularly). They are wearing great, which
I did not expect (I expected them to wear faster...softer rubber... that sort
of thing) and they continue to hold the curves like a mongoose with a snake. So
if "heating up" is an issue, I have not seen it.

Additionally, the wheel shimmy, which the original Bridgestones exhibited after
a while, is totally absent with the Pirellis.

I am curious to hear other responses to this aspect of tires.
