I've been commuting from Pinehurst (between Northgate and Lake City) to DT Seattle 3-4 times a week. So far, the weather has been relatively co-operative. I've ridden through some serious rain a few times, but my rides have been mostly okay, if not pleasant.
Now as the temperatures often dip into the low 30s in the morning, I'm somewhat concerned about the road condition. I wouldn't be surprised to run into some icy pavement pretty soon, if not this week.
So my fellow Seattleites, what kind of tyres do you have for the winter commute? I have the Bontrager All-Weather tyres (700x28s) that came with the bike. They have about 1,200 miles on them, and as far as I can tell, they still work well. I wonder how those "all-weather" tyres can handle incremental weather. Should I invest into a pair of snow tyres? If so, which brands do you guys recommend?
