Read an article in the november issue 4x4 magazine , and winter tyres will now last a lot longer now than the softer compound used in the past, It is possible to run winter tyres throughout the year .
Winter tyre treads work very differently to the standard tyre and treads which means a different type of handling in varying conditions and it may be that you need to inform your insurance company .
Most know how awkward insurance companies can be and the last thing you need is an insurance company wriggling out of claim because of something minor ,
I would phone Insurance if i was fitting winter tyres . MIKE
