Silly frickin' question I know but...........
Do knobblies really make that much difference in the ice and snow?
(apart from deep snow, I'm on about the slushy rubbish we have darn sarf).
Is there really that much difference in contact patch?
Surely when you hit ice you are going to go whatever happens!
The reason I am asking is that I am still on City jet slicks, it is frosty but not snowy (yet).
When do I change tyres for knobblies again?
A couple of years ago myself and a friend decided it would be a laugh to cycle home from work through the un-gritted lanes. The surface was sheet ice with a bit of snow. He had a full on MTB with knobblies and I had a commuter MTB with grooved slicks. Neither of us had any grip whatsoever. We made our way back to the main road by the shortest route but even that took ages and we both ended up on our asses more than a few times. It was a laugh though, but only because there was two of us. Had I have been on my own it woudldn't have been any fun.
