0-60 in 4 seconds is supercar fast. You might have miscalculated your time before you bought new tires. Assuming the tires are radials, lower the pressure in the rear tires to about 20psi.& you should get better traction. Of course, 20psi is too low for every day driving. -----Original Message----- From: car man [mailto:carbuyer02@xxxx] Sent: Thursday, May 29, 2003 2:12 PM To: Chrysler300@xxxxxxxxxxxxxxx Subject: [Chrysler300] question about tire pressure does anyone know what the tire pressure sepose to be on my tires??? for my 1970 chrysler 300 with 440 engine i told the guy and he put all my tires at 32psi ig to new tires . he says it wears evenly but my car well i know you are gonna be mad at this but i used to do 0-60 in about 4 seconds now it like 0-60 in 7 seconds there got to be sormething wrong thank you for your help shawn _________________________________________________________________ MSN 8 helps eliminate e-mail viruses.
