Hi Peter,
tires are a piont i am not really happy with this.
I like to make the Europa as much as i can to original condítion, so i decide to put on the front 175/70HR13 and rear 185/70HR13 tires. This is the original tire size for the TC alu rims. But i Germany it is impossible to get this size in HR till 210km/h from a well known tire company. You only can get China tires. So i ordered a set from Nankang. I have no experience with them, but after driving them around 400km now, it look likes they are not bad in dry conditions. I will not drive in rainy weather or i am very careful.
So in the Moment i have no other option in this size of tires but they feel not bad in the moment. I drive them a bit sporty today and the car makes nothing funny things. For me the Europa is a historic car and i must not win a race with him so the tires are good enough for the Moment.
