December 6th - It’s time for the winter boots again. A couple of times this week I’ve felt that queasy adrenaline rush as either the front or real wheel slipped a little bit while cornering. Such incidents are rare, but a wakeup call I always heed. Nature is telling me that it’s time to swap out the 28mm Marathon Plus tyres and throw on the 38mm Marathon Winter. These are a fatter, lower pressure road tyre exhibiting a chunky tread made from a soft compound with small tungsten carbide studs inlaid that bite into ice, mud and road debris. They’re noisy, don’t roll too well, but grip, even on black ice, like demons. They’re not cheap, but for any commuter who keeps going through rough conditions, I highly recommend them.
