After my first Spring ride last week I wanted to change my Michelin Pro 3 tires to a set of Michelin Krylions as the roads in NJ are still cluttered with debris. To make a long story short, after struggling for half an hour to remove the tire, and having bruised thumbs and a bleeding thumbnail, I put the project aside. I just couldn't get the bead over the rim to dismount, nor back on the rim to remount.
An internet search revealed a simple answer...apply the heat from a hair dryer to the section of tire that refused to go over the rim. 3-4 minutes after heat was applied my tire was back on the rim.
For the time being, I am not mounting the Krylions as I broke my tire lever during the struggle, and I don't want to go out minus the lever. New levers have been ordered. Not that a lever would do me any good on a cold day with the Pro 3's, anyhow. Perhaps a couple of chemically activated hand warmers ought to be stowed in my saddle bag for cold weather tire removal emergencies. What a pain, but better for-armed than left out in the cold, miles from home, with a recalcitrant tire.
