DIY ice tires can make your wintertime biking safer and smarter, and the materials you'll need to modify your tires can cost as little as $5, while commercial ice tires cost up to $60. If you're even moderately handy with some simple tools, can make it out to a hardware store and back, have or can get a pair of bike tires you can dedicate solely to winter riding, and have nothing against making your biking experience better, check out these project guides and give one a whirl. The basic idea is that you add studs to your bike tires, much like putting chains around the tires of a car or truck, to help your wheels keep their grip in ice and light snow. This reduces skidding and slipping, so you can pedal without mishap. It's great and green to ride your bike in cold weather to reduce your carbon footprint, and it's even sweeter when you're doing it as safely as possible.
