You can tell winter is here when...

.. the front wheel slides to the side when you turn or brake.
Hmm methinks there must be a solution to the problem of sliding wheels and unstable baby trailers on ice.

There is, 700c Nokian Hakkapeliitta W106 35mm. What I hear you say, well look above, see the carbide studs in the body of the tire.
Wow they work well. They grip the slippery stuff like a Gekko to a wall.
Downside, they are so noisy, like a herd of mice in hobnails and the drag on tarmac is unreal but it is getting me fit:)
