My current rear tire is a Dunlop 190/60R/17. This size is only made by Dunlop and Bridgestone.
Avon makes a 180/60R/17. How much differents is there between a 190/60R/17 tire and a 180/60R/17 tire?
From looking at a tire chart. The 190 and the 180 is the section width in mm. So one is 10 mm wider then the other? Could the 180 be used in place of the 190? What effect would there be?
