Tire pressure

["G Rierson" <glenn.rierson@verizon.net>]

I just mounted a set of Yokohama Avid T4's as an alternate set to the Michelin
Red-lines.  The Yoko's are 205/70R/15 and I put 24 lbs in the front and 28 lbs
in the rear.  I also went with Goodparts up rated springs and gas shocks
(conversion ) on the front and rear. The tires seem soft.  What is a good
pressure for "spirited road driving"?

Thanks,
