thats weird.... the reviews both on g35driver.com and on tire rack say this car can get over 20k on these tires easily. one guy replaced rears and double stinted the fronts, getting almost 42k on them. the OEM potenzas wore really quickly, and i can tell the PS2s already have a lot more grip than RE050s did. im excited to actually drive them. i'll probably take them out on a real drive this week, and autox on them early april.
