I'll just hijack this thread to tell about my expriences: I've been through some struggle to find suitable rims for winter use - I was looking for steel rims and though we have the numbers (and you are missing the centre hub diameter: it's 58 mm), it wasn't easy.
One option was to purchase some steel rims from Simon that he lists at 5.5J14 but at a price of over 80 EUR plus transport costs it was just too much. Another was to buy spacers - Simon has some at 15 mm which would permit me to use an offset of 43 mm, but at 50 EUR a piece (!) it's just too expensive.
But it turns out Borbet has an alloy rim "CA" that they supply as 6J14 ET30 - I found it by searching a german site for rims for Fiat Marea 1.8 and there it was for only 69 EUR a piece plus a bit of extra charge for sending them to Denmark. Offset 30 is two mm off, but that's ok for now. I hope it will look good
This is the one:
(and I do not want to hear comments on whether it will look good or not - remember, I had no other option! But I think it will be okay.......)
I'll order four of those and have them fitted with Pirelli winter tyres so me and my car will be safe during the winter
That's one issue down - the car is still not through the tests...........
