so this recent blast of arctic love that boston recieved has me thinking about the upcoming months. first thing i do when i get back to town and return to work is get new tires. im riding 700x18 wheels /w bontrager race lite tires and am wondering if there are any tires out there that'll make much of a difference.

this is my first winter here, should i be concentrating more on taking it easy in ****** conditions or putting money aside for a new wheelset?
