ok, in a recent post involving someone using a 160/70 rear tire. It struck my that you guys need to know how tire sizes work. Just because the front is a 120/70, if the rear is a 160/70 that DOES NOT mean they are the same profile, quite different in fact. Let's use a 160/60ZR17 for an example (this is the same for EVERY tire size).
160 - the width of the tread in millimeters, in this case 160mm
60 - the ASPECT RATIO that means the sidewall height is 60% of 160mm or in this case 96mm.
Z - the speed rating
R17 - Rim size in inches, in this case 17" rim.
so that is how it works.
