Hi. I’m looking for a few complete summer tyres for my VW Passat 35i, Bj 96. I’ve already found some, with the right tyre size. The tyres are registered ( 205/50 R 15). My question now: Do I have to register the new rims and if so – how does that work and what would it cost? Rims are not listed in the vehicle letter… There is only one part-certificate for the complete wheels. Is that enough to register the tyres? To the rims: Nam e by the manufacturer Rondell 7Jx15 H2 ET28 and the hole circle is 4×100.
