Wow, thanks a ton for the great info, BobbyG! I think one of the first things I do will be adding tire liners. Back in June I added Mr Tuffy liners to my (only) other bike after getting two flats in one week. I haven't had a flat since, almost 2000 miles later.

Regarding the Kwest tires you got, did you stick with the same width as the original tires (700x32?) or get a different width?

Thanks again for the info.
