I currently have 195/60-R16 summer tyres, and the only reasonably priced winter ones in this size (with the High Load rating I need in the Galaxy) are M+S Dunlop Winter Sport M2s, but note that they are sometimes described as commercvial or van tyres.

Does this matter (given the Galaxy is a bit like a van in any case!)?

My local tyre dealer, who I respect greatly, said the tyres on my 2001 VW Sharan were commercial tyres, so, it sounds like you are getting consistent advice to me.......

The old terms "commercial", "van" , "6-ply" and "8-ply" aren't really relevant anymore - it's all down to the tyre Load Index marked on the sidewall which must equal or exceed the maximum permitted axle load for the vehicle.

A number of MPVs and SUVs need tyres with Load Index such that they're considered "van" tyres.

Many thanks - and am I right about it being acceptable/legal/no insurance issue for the speed rating for winter tyres being 1 less than summer?
