65 profile rear tyre

Post by Jay762 »

I normally run a 180 55 17 rear on my 89R and have seen some Conti Race attacks for a great price... but they are a 180 65 17 spec

Has anyone used this 65 profile and were there any issues - swingarm clearance etc?

180/55 is 55% of 180mm = 99mm
180/65 is 65% of 180mm = 117mm

Your side wall height will be 18mm higher with the 180/65/17
