Just a reminder that on the bike & footh paths here in Oulu 🇫🇮, 2 cm of new snowfall must always be gone within 3 hours, on entire 166 km main 🚲🚶 network, 24/7. Maintenance needs to be fast, reliable & efficient, so that people can rely on it 👌 Join our Urbanism Masterclasses to learn more! 🤗

@pekkatahkola I assume this is just removing the depth, and cyclists still need tyres that can cope with the compacted snow underneath. How different are winter tyres from 'normal' or summer bicycle tyres?

@trantion @pekkatahkola When the snow is plowed well and the resulting surface is even, plain normal tires ("summer" tires as they sometimes are called) work most days just fine.

Studded bike winter tires are common here in winter and they allow paying less attention to the available grip, but e.g. I'm using the same tires year round in Oulu.

Winter tires should also be made of a different rubber-mix than the summer tires. Not like schwalbe that seems to use the same mix for both. The winter mix should be softer in low temperatures, the summer ones usually becomes stone hard and pretty useless on ice with no grip whatsoever. I'm using Nokian studed tires in Umeå. We don't have as well plowed roads as Oulu so we need better tires 🙂
