I have never used commercially made studded tyres... I am too Scottish to pay that kind of money for them.
Our roads were a skating rink last night and I was running on those 700:35 cross tyres with the front being studded and was blowing past cars, pedestrians, and other cyclists who could not handle the roads.
Was riding this set up... it's the lightest and fastest winter bike I have ever cobbled together and I built it up for my friend but had to do some test riding to make sure it would be suitable for a new winter rider.
I might be studding the rear tire as well.
My last self studded tire just got retired after 4 seasons of winter riding... the screws were starting to tear through the tire casing and I need to build up a new 26 inch studded tire.
