i don't consider 8 psi as low. over the years of using the same sized slick, (32x14 with stiff sidewall), i found 8-8.5 optimum pressure for my car, (2959lbs with my fat ass in the chair). i was running 12 psi when i started but found i was running the middle of the slick bald before the sides were loosing all their depth dots. i went lower over the next few seasons settling into the 8's with no adverse affect in top end handling, if fact my 60's improved. when you change to new slicks, cut your old ones open & measure the thickness across the middle, you could be quite surprised.
