dodnkeytrousers

I have 17" teron alloys. I am looking to buy one as a spare. I understand the tyre size numbers (225/45 ZR17 94W), but for a spare rim do I have to get the exact same oem (mfr part no) numbers (5e0071497a8z8)? I see several option available but the second-hand ones, while the correct size, have different oem numbers. Many thanks for any advice.

We had (with our mk 2) a very long saga of regassing and endless bills. Eventually one garage found tiny pinholes in the radiator that were causing it. After that - bliss and no further probs. Worth a very close look...
