I need new tires for my ST1100, Decided on Michelins P3s I have read the posts on these and am thinking the shorter 170/60/17 for the rear will be good for my shorter inseam. ( I have a metal fab shop so shortning the stands is not an issue) Should I consider 110/70/18 or a 120/70/18 for the front to also lower the front a bit? Has anyone done the larger (120) tire on the front?
