We had a set of these https://www.oponeo.co.uk/tyre/vredestein-quatrac-175-65-r15-84-h#324704603 fitted yesterday on our 2014 Trekking replacing the original Continental Cross Climates. First impressions are good, better grip and much less noise. They have the M+S and mountain symbol same as the Contis so it will be interesting to see how they perform long term.
The Quatrac's have been a long time popular tyre on these pages, similar in overall performance to the Goodyear 4Seasons Vector (now in Gen-3 guise), the Michelin Cross Climate and Conti AllSeasonContact. New tyres always feel better than older ones - not least due to the quieter running on account of deeper tread- depth over the old set - but I am not surprised that you like the feel of the Vredesteins, as they are very good tyres.
I have this time tried running a full winter tyre all year round in the Conti WinterContact TS860P. Light(ish) cars like the Panda are far easier on tyres with more flexible blocks than big, heavy ones and I have now run them for about 16 months and 11,000 miles and they are wearing surprisingly well. The wet and cold weather grip is exceptional, as you would expect and the VERY brief foray into the hills on the one snowy day we had here in the South last year proved that there's a reason that they won a lot of the Winter Tyre Tests last year. Sure they move around a little in the hot weather when pushing on, but nothing untoward to be honest. I have a much heavier car in the garage but that needs its winter wheels/tyres fitted only in winter, as they really do feel out of their depth if the climate warms up too much before I get round to switching them over.
