In my parking hall there is a Citroën C5 first-generation station wagon. It is an heirloom that I “save” for a relative. The car is rarely driven, it comes together perhaps 5000km a year. I still have two sets of tyres, but both WR and SR are almost 10 years old, so they have to be replaced. Since the two-time bike change is hardly worth it and a new purchase of two sets of tires certainly not at all, I think, the car on all-year tires z With very wintery road conditions, the car is only very rarely used, in the summer you do not drive long distances. On compact graders should by now be very neat all year round tires – but what does this look like on heavy car like the C5 (which weighs well and likes its 1700kg)? Does anyone have experience with GJR on a comparable car? Are there perhaps even emulations for a particular tire?
