all season tires advice - winter tires dimension instead...

[Francois.Pettorelli]

hello all, (sorry I don't speak swedish well enough and my keyboard does not even have the special letters , you can answer in swedish or english as you prefer)
I am new in the corvette "tobe" community in Göteborg. I am reflecting to buy a C5 soon and need your help and local experience to ease the decision.

I want to be able to drive the car all season except on dangerous ice and snow condition (in which I would not drive any car anyway ). I am therefore looking at tires for all season for an ordinary C5 convertible. do you have any good tips and brand/model advices available in Sweden?
I am lost in between sommardäck and friktion vinterdäck .... where would I find the all season?

thank you in advance for your answers,
regards,
Francois

Looks like all season tires are not allowed for winter driving in Sweden, anyway it is not possible to have a Y speed index in the European all season tires, which makes them illegal for the summer period.
So now I am up for normal winter tires. Anyone has the experience on a C5? The 275/40-18 is almost impossible to find in winter. The circonference is equal to 245/45-18 or similar to 255/45-18, but do they fit on the standard C5 rim?
Thank you to share your experience.
Mvh,
Francois
