I usually change tyres in winter and spring paying 120 CHF for 4 tyres (using the same rims, so basically dismount the ones in use and mount the other set on the same rims).
Problem is that this place is quite far (1 hr drive) from where I live (goldcoast).
So far I only found places nearby that costs about the double.
Do you know any place that is charging around 120 CHF for 4 tyres in the area of Seefeld, Zollikon, Küsnacht, Zumikon etc.?
