It's way too early to think of snow and ice covered roads -- some of the best riding is yet to come. But when it does come, you'll want to be prepared if you plan to ride all winter.
We carry the Nokian Hakkapellitta in 700 X 35 C and the Mount and Ground in 26 X 1.9 sizes. We have a decent stock of both and will get more in the next few weeks.
They are $60 each for both sizes but you can buy a set for $100. We recommend a set over just putting one on the front or rear.
