PS -

My bike is also a fixed gear and have to say the combination of this and those DIY studded tyres makes this my best winter bike ever.

The front tyre is going onto it's 3rd or 4th season and figure it has more than 10,000 km on it... it hardly shows any wear to itself or the studs.

The rear tyre came studded (another diy job) and I don't know how many miles it has on it... the off camber studding was nicely done.

I work as a messenger and found that with our current weather (snow and ice) that I have been getting around faster than most... I am the only guy running studs and found I can still maintain some pretty good speed and retain great stopping ability and handling.
