Fellow Boston rider here. The A 10's will not be up to the task. Best to get another bike with some bigger tires. Plus the winter sand and salt will destroy your ride in no time. I use 700 x 35 and 26 x 1.95 studded tires. Sometimes 29 x2.1 and looking forward to commuting on 26 x4.0 tires. Look at some thing like the 45 north gravadals in 700 x 38. A hybrid or used cross bike would work.
