This can’t be good–most bikes don’t use studded front tires. The Triumph is now seven years old and on its original tires, though they have accumulated only 2600 miles. I suppose this will get me to replace them. (I’m not quite sure what I’ve collected, here…I thought it was a bolt, but on further study, I don’t think it is.)
I discovered this on the ferry, headed out to Kirkland for the Carillon Point car show today, so I had 50 miles of riding to contemplate my unwanted companion.
