Looking for a tire you can keep riding through the winter, but won't slow you down in nice weather?  Continental's Travel Contact is the winter tire of choice for many.  It boasts a slick center, with some pretty aggressive knobs on the side for extreme grip while cornering.

Originally designed for heavy-duty, on/off road world touring, this is a tire that's going to feel right on gravel and pavement, wet or dry.  Continental used their high-mileage compound and extreme puncture resistance so that you know this baby is going to roll for a long time. 

Try it out for commuting, touring, or cyclocross.
