Yikes, didn't realise there is such a limited choice for 19" winter tyres
Now I have a choice of paying CHF 1600 (USD1311) just for the scorpion tyres on my existing 19", or CHF 4800 (USD3900) for a 18" complete set. Probably going to go for the cheaper option. Randomly searching online for local Swiss suppliers I found
Pirelli 275/45R19 108V XL RB Scorpion Ice&Snow
and then
Pirelli 275/45R19 108V XL Scorpion Ice&Snow RB
I guess they are the same, except a few dollars in price

Are these N rated or the narrow ones? Thanks for the advice!
