I know my ST 1300 standard rear tire is supposed to be a 170/60/17 but I can only find a 180/55/17 in the Mich PR4. Anyone know if it will fit?
A number of owners use the 180/55ZR17 tire on their ST1300s. Some even prefer it.I know my ST 1300 standard rear tire is supposed to be a 170/60/17 but I can only find a 180/55/17 in the Mich PR4. Anyone know if it will fit?
in theory.Difference in radius is 3mm between 170/60 vs. 180/55 tyre.
True, sizing is nominal and not absolute. The original Michelin Pilot Roads in ST sizes featured a very rounded cross section and the ST1300 OEM Bridgestones had shorter sidewalls and in cross section were more elliptical making the former rather vague tipping in a corner while the Bridgestones were crisper at tip-in.in theory.
Years ago I kept a running record of different tire sizes I ran on my ST1100, where I measured the width in mm and the circumference in mm. There was quite a variation among tires of the same nominal size, so they're not all the same regardless of indicated size.
Thanks everyone. That helps a lot.I know my ST 1300 standard rear tire is supposed to be a 170/60/17 but I can only find a 180/55/17 in the Mich PR4. Anyone know if it will fit?
