Now, I'm a winter tyre fan-boi but even I struggle to believe winter tyres will give much grip on sheet ice. There's little friction able to be generated between ANY tyre and solid, smooth ice, so it's unlikely winter tyres will be much better than regular ones on sheet ice. Their tread pattern design and the compound are designed to work better in snow (deeper grooves to clear it etc) and the compound works better when cold, but the only thing that's going to significantly improve matters on ice is spiked tyres...Blue said:Mr Whippy - Winter tyres can grip even on an ice rink so they will definitely help even on compacted snow and ice.
