Is it OK to leave winter tires on in 20 C temperature, for 2 months, assuming the car will be making 50 km per week only?
There are lots of sources explaining you should not drive in hot weather but they don’t explain if it’s OK if you are driving barely or not at all.
EDIT: Thanks for the answers. Someone asked me to clarify what do I mean by "OK": I meant whether it is economically rational, e.g. I'm not ruining my tires just because they sit in 20 C on a not moving car, right? Other than that, I know it's not wise to actively use the car without replacing with summer tires. And I don't care the legal stuff.
