No, not my normal falling off stuff. Inspired by the snow tyre thread somewhere on here I thought I would give it a go:

Then I fitted them to the first wheel that came to hand. It was the fixed wheel and to make it worse there was a cross wheel at the front.

The grip is amazing and it is really easy to pop the front wheel over obstacles. I think the tyre would suit a downhill/freeride/all mountain (Heavy) sort of bike more than a light weight like me.

Quite good for picking up leaves though
