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

The chains add more traction for when there is ice on the road. It is similar to using cleats in soccer (or football). If you have an all wheel drive car and are familiar with the terrain, you don’t really need them however.
