This past weekend we loaded up our bikes and did the 'Ride for Wishes' a part of the Make a Wish Foundation. It was great fun and now we are searching the internet for more rides in the southeast to ride in. We rode over an bridge that I wondered if we could really make it over! It was great.

I've decided that I'd like to change out my tires to a narrower tire. One person told me it could be done but when I talked to the guy at the bike shop, he said I couldn't go any smaller. He said something about me going to a higher pressure tire. <- Why would I want to do that? What would be the advantages?

So, how do you know if you can change your tires (to a smaller one) without changing your wheels?
