To stay off I-95, I am committed to continue my train and cycle commute in all weather conditions. I ride a total of 18-20 miles in 4 sections. Home to train, train to work and return. I am riding a stock Trek 520, new in March 2012. Tires are the original Bontrager 700x32. Since March this year I have handled several steady rains, downpours and a thunderstorm or two. Rain hasn't been a problem. Traction in the wet hasn’t been a problem. My concern here in Northern VA as winter approaches will be icy conditions, black ice or even a commute in snowy slush.
Would I be better off with a more aggressive cyclocross tire? I am on paved roads the whole way but I am expecting that if there is enough snow to plow that the bike lanes will be snow covered.
