I hvae a 04 with 47000 an when new it was very smooth,then the fist set of tires where dunlaps,wobble an shake,so I tryed these stones and a lot better and have had these ever since.This spring I ordered the centramatic balance system because of all of the great reviewes on shake and tire wear. Our first ride was this past weekend and so far not sure,BUT the 70ser.tire I love the increase in tire size and extra load (we always ride 2up and with a trailer)As soon as we left the drive the back felt like a snow tire with the big knobs (I think the tread is too far apart or too agressive)I hope this will wear in and smooth out! I sure wish that Michelin would make tires for 1800's.
