If you notice on the first post my Le Tour 650B has the CR18 rims and the tires were almost impossible to mount. I have since acquired the Col de la Vie tires since these pics were taken and they were still harder than heck to mount (I ruined a few tubes with the metal tire levers getting them on).

Unfortunately my Le Tour is just a commuter/townie ride since I wouldn't trust it on a tour where I'm far away from home (or the bus!). I would be screwed if I got a flat!
