Agree 100% - I have other vehicles and we do exactly that - one of mine stayed on them till May lol - I have had Sottozeros before on a Porsche and also on my last AMG (SL63) - they were brilliantYou won’t believe the difference on a set of quality winter tyres - there will be a more noticeable positive difference for you car than the vast majority, and especially in cold frosty mornings.
Which model is yours? Pirelli Sottozero are available in sizes suitable for both 11 and 12 inch rear wheels. Pop them on at the end of September and they’ll already perform better than MPSC2 or even MPSS.
Just havent got round to buying a set - will do though
