High Performance All Season Tires

[BFM]

Edgar, but what do you do.   You have a full set (with rims) of summer tires & a full set (with rims) of winter tires?   Or do you mount/dismount & just switch the tires?  Or you just run on summer tires all year round & take the risk?

I am torn as to what is the best route if you use your GS as a daily driver as I do

I have the same situation like Edgar, a daily GS. We both have a full set with rims of summer tires and a full set of rims for winter tires.
Switching twice every year on the same rim is a good way to damage the rim and leave you crying, and it's a waste of money, too.

Having an extra set of rims with winter tires can be expensive, too, but the rims don't have to be original. That's why some of us have the Schmidt Drago rims for the winter, they're cheaper (though not REALLY cheap).

I generally wouldn't take the risk and run on summer tires all year round... generally. Of course it depends on where you live and how the weather conditions are there. Keep in mind that the cold is not your enemy. Summer tires still grip better than winter tires when it's dry. But only then, it all goes out the window when it's getting wet.
I don't drive much these days with Corona and working from home (aka Home Office in Germany ). So might not switch to winter tires this year. Also because i have an inspection coming up in February and i need to have the C on the summer set.

About the very spirited driving: This is basically driving the car to it's limits. You can always do that, no matter the car or the tires. You can reach the limit in any case, the difference is the speed and the overall feel of the car when you do. Here the limiting factor is the all-season tires. So in the end, you will just not be as quick. But crippling the car by putting all-seasons on just doesn't make sense to me.
Imagine a scenario when you're driving fast and happen to meet an M4 with summer tires in the summer (or winter ties in the winter) and he just disappears because you just can't keep up because of a lack of grip. Now that does not feel right, does it?
