Nice! Yes I do carry one extra tire with me, usually an inexpensive Schwable that cost about $23. I also put the Tufo sealant in the tire after it is mounted and carry a small tube of it with me in the seat bag with the extra tire. As mentioned, I use the Tufo tape. I have used Conti glue which sure sticks fine but the mess and waiting 24 hours for it to fully cure after mounting the tire was not practical for me. The tape goes on quick and easy and off you go. The Tufo site has a Quick Time movie of the installation. I know I must sound like an ad for Tufo, and I know some people don't like their products, but I have been pleased with them.
