That's when wet. Stopping distances are increased when dry with winter tyres but back to the 5%.

Do you know what the % difference is in stopping distances between a tyre that is down to 4mm and one that is down to 2mm? Or the difference between 8mm (new) and 1.6mm (legal min)? It's more like a 40% decrease. 5% is often quoted but it's never put into context. Emperor's New Clothes.

And this is coming from someone who has spent over 2,000 on a set of winter wheels and tyres. They are useful for snow and ice but any safety improvements on wet or dry roads in 5C are negligible in comparison to improvement you get from simply replacing your summer or all season tyres sooner
