Have 6 years and 6000 miles on my Michelin Pilot Sport tires.  Great tires, were always a little loud at high speeds.  No complaints for sure.  Decided to pull them off and change tires, mainly because of tire age, but these tires never were exposed to outside elements, beaten, burned out, etc.  They are fine.  Was also looking for a newer tread design.

Wednesday Hemotox got new dancing shoes.  NITTO INVOs, 295x35x18 on fronts, 345x30 19s on rears.  Incredible ride, grip like nobody's business!  Hemotox and owner very happy!

Cool! Looks good Doc! I just got the Invos for my sons car too.
Good move to change the old hard tires to some fresh rubber, much safer.
