What are the rules about winter tyres and snow chains in Switzerland?

Snow tires do not help on ice.

My friends and I used to race on frozen lakes, so I DO understand ice.

As said, it is a discussion- if it annoys you, you can leave it.

Tom (Tom ...) oh yes they do

Winter tires gain their advantage not only because they have superior tread patterns that are designed for traction on ice and snow, but because they employ softer rubber compounds to enhance grip.

Create an initiative.

Tom

There is NO grip on ice, EVER (unless you have spikes)!

Tom

FWIW one every 84 Km

But I do agree on distance!

Fact of life. Idiots prevent poverty.

i groan because you haven't thought it through. in countries where winter tyres are compulsory, there are always times and places where the current rules are not appropriate. for example in italy in many places winter tyres are compulsory nov 15 to march 15. but at each end of this time it might be over 20 degrees and winter tyres would be inappropriate. then there is no rule for summer tyres so you see lots of people with worn out and tacky winter tyres when its 35 degrees in summer. much better to have a rule which says you must be suitably equipped for the conditions which is surprise surprise the rule in switzerland.

(just put the last of my daily drivers onto winters today).

used to? with livigno so close you still should!

I'm going to disagree - to an extent.

On that black, shiny, smooth ice - winter tyres are no help at all.

On that crusty, rough ice, they do give a fair amount of grip.

In a thread that's about safety, grip and driving with appropriate tires: Irony

No, it doesn't annoy me. It's an interesting discussion. However, you did write initially:

I pointed out to you that with your direct democracy, you could actually do something about it.

lose some air - you'd make surface 4x standard - go as low as 1.4Bar on 2Ton car , than test summer vs winer tiers - straight line breaking from 50-0. Measure the distance. Show the results. And here the winner is ...

They could make winter tyres mandatory from December to January and summer tires from July to August. That way people will change them when it's weather-appropriate but it ensures they will change them.

But putting it into law is not necessarily an answer since there are so many types of tyres going around nowadays. Someone going around with cheap chinese tyres both winter and summer is more dangerous all year round. Maybe we should also ban cheap tyres. And maybe more people would resort to 4 season tyres, which are also not optimal.

I think when it snows fines should be handed out en masse to people on summer tyres as prevention.

This would be simpler. Roadside checks in small roads during snow days. Fine if the right tires are missing. They do roadside checks for driver license and alcohol anyway, it takes 30 seconds more to check the tires.

Essentially winter tyres are obligatory as if you have an accident or get stuck and block traffic or roads you are deemed "not to be properly equipped for prevailing conditions" and it all becomes 100% your responsibility.

Most of us know this and understand the importance of winter tyres in an Alpine country, tough shit to all the others who have problems with this concept.

they do here.

That's an interesting idea. In the in-between month the onus would still be on you to have the weather/season appropriate tires for where you live/drive but enshrine the seasonal switch, thus making it more likely that you did the right thing. That might actually work .

All Season tires are not optimal in Summer, but in winter/wet driving conditions this years' All Seasons are comparing very favourably to winter tires in testing. They could be a reasonable option depending on the way you use your car. I'm mounting them on my camper, where I hope to be driving from cold to warm and vice versa (corona permitting) and where the season specific ones would be the wrong choice at my destination.

... and another car goes off the road on a bend going downhill yesterday- and stopping 30m down in a field. Driver miraculously not injured and no-one else involved. Car is a write-off ...

Ah well- roads are REALLY bad at the moment!

IMPORTANT NEWS

By using winter tyres for about 6 months of the year, summer tyres will last about 100% longer than previously expected under normal conditions

Did he have summer tyres?
