Time for new tires (either Michelins or Continentals) and MAYBE new rims. Look at all the leaking on this current rim. All four have had this problem at one time or another and now one is leaking again. Can these really be cleaned up for the long haul? Or will this be a constant problem.? I like the look of the OEM rims so would probably get replicas if its time for new rims. Also does anybody know the part number of these OEM rims (they are 20")?
