The 180/55 will fit and work just fine! Yep, a 180/55 from one manufacturer will sometimes have a different profile than another. Bottom line is that the 180/55 will slow your side to side transitions somewhat in comparison with the 170/60, but it's very slight and probably imperceptible by some.

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
