Last year I changed my front tire to the 120/70 and was pleasantly impressed....thanks y'all. But this year I was offered a Bridgestone 020 tire for free if I want it. The only catch is that it's 180/55 instead of the factory 170/60. I compared them side by side in one of the local shops yesterday and the 180 was less than 3/8" smaller in diameter than the 170. Of course they were unmounted, so this could change.
I thought I'd see what my "all-knowing" GTS comrades know about changing the rear tire to this size. GWN Daren
