Year-round VS summer/winter tyres

Hello! I’ve already looked in the help, but it was as always out of function! I don’t want to break a winter tire discussion from the fence!!! Because now I’m about to decide what to do with my tires in autumn. At the moment, i.e. for the next 3 months I drive 2,500 km a month, a lot of BAB with me. The Twingo now has 40,000 km, the front tires don’t look so beautiful anymore (it’s probably only been moved in the city center traffic before, turned with servo on the spot or something like that) The winter tires on steel rims from Astra (175 R 13) have a different hole measure (?) and do not fit. Very bad, because they are only 1 1⁄2 years old and have still 6 or 7 mm. Found a tyre dealer who would take them in payment. One problem less, because with ebay or on the black board you will not get rid of them. What should I do? I love with all-year tires. Goodyear Vector 5 have actually done quite well in tests and on the consumer pages (Ciao.com). The rubber compound has to withstand a lot. Everything from -15 to + 40 degrees is actually there. The constant conversion, the costs for storing and the new investment for steel rims speak against the summer/winter duo. Besides, I will probably only drive the car for 2 years and sell, BEFORE the repairs start. So, who has experience with all-year tires? Ahoi Tex
