The bead was separating from the sidewall on the left side of my front tire. The tire only has about 400 miles on it. Very frustrating. What's more, I wasn't sure how I was going to repair it. Just as I was contemplating my fate, Bill Cunningham with the SPP rolled up on his way to Northrup Grumman. And he had a tire boot in his kit. I was saved! The boot is a tough vinyl patch with a supper adhesive for patching a torn or split sidewall long enough to get you home.
It worked. I made it to the office and back home again. I had already concluded I didn't care for these tires as the tread seemed to have terrible grip on wet pavement. The whole reason I'd gone to a fatter tire for the winter commute was for better grip and a little more forgiving of road obstacles. This set was neither and I had a new set of Continental Touring Plus tires waiting at home to go on the bike. So once home I went straight to BD for a set of those tire boots to include in my own kit and a couple fresh fat tubes to go with touring tires.
A quick test ride confirmed I had the new touring tires mounted without any unusual bumps or wobbles before I put the bike away for the night.
I owe Bill breakfast at the next weekend opportunity.
