how exactly does it make a difference to put chains on tyres for driving in snow?

Question

I am from a country that has little to no snow, so no need for snow tyres. The putting on of chains doesn’t really make sense to me. Also, are there such things as actual snow tyres or does the term snow tyres just refer to putting the chains on?

Answer 1

Chain’s or cables did into the ice/snow to give you better traction. And yes, snow tires are real. They are generally softer and have a bunch of siping.
