I was on my way to work one morning and was passing a truck when I heard one of the trailer tires starting to SLAP SLAP SLAP SLAP really loud. I assumed that wasn't good, so canned it and passed him like he was standing still. Once I was about 20 feet in front of the truck, I noticed some pretty flashing red and blue lights in the rearview.
When one of Minnesota's finest came up to the bike, I explained about the tire and once he checked my record - squeaky clean now that I've "grown up"
( well, kinda
), he told me to have a nice day and watch out for those tires! NICE!
