Tyres/wheels for the V50

Hello, I’m new here, but I’ve been reading silently for quite a while. Last year I bought my first used elk (V50, 1.6 D) and I’m actually quite satisfied. Only with the current tire, which of course is not due to the speed. Had the series tire on it on steel rim and would now like to change to something chiceres. Imagine me in any case 17 inches, like with 205 or 215 tires. Would like to use the wide selection of non-original rims (come on cheaply) and have no idea what is possible there. Read everywhere that you have to build bricks or car parts. Actually, I am the classic series vehicle driver and have never bothered with anything like that. What can you recommend there? Have looked around me at Dezent and Brock and I like this one or other (Dezent: V, N, Brock: B 21, B 24), but that never fits 100% to the EEC regulations.
