Passat B6, What tyre size?

[Buzz_B6]

I'm looking to buy a ice set of alloys for my B6, but i'm not sure what tyre size i'm best with. Actually, i'm not sure what offset i need to order either!

The standard 16" alloys i'm keeping as winter wheels since they're all corroded anyway, but for summer i want to fit 18" wheels

So i have 3 questions. It is my intention to lower 25-35mm at the same time, so that i dont leave massive wheelarch gaps by fitting 18's.

1) I presume i wont be fouling the arches with a 2" wheel increase, and such a small lowering?

2) If the wheels are 5x112, what offset do i need? ET35 or ET45?

3) What tyresize is most common on the B6 for 18's?

i've used a tyrecalc and get 2 or 3 cobinations that keep the rolling radius the same, and will keep my speedo accurate, but i'd rather have the most common size.

Thanks in advance for any answers

Buzz, I have 18" OZ Superturismo on my B6, so hopefully I can help a bit. I don't know anything about the lowering, but you could easily get away with a 25-35mm drop as there is a big enough gap between the wheels and arches.
I really dont have a clue about the offset as I ordered my wheels direct from OZ in Italy and they sorted me out with all the spacers, etc. Finally my tyre size is 225/40/ZR18 and I'm using Falken FK452 tyres. Hope this helps :p

Wasnt sure if 225 would be wide enough on an 8" wide tyre

been tempted by these on ebay, but haven't taken the plunge, (yet)

Buzz my wheels are 8" wide and they fit on the tyre no problem

I've just bought a 2007 TDI Sport with 17's they come with 235/45 17s. Therefore I would suggest you need 235/40 18.

Theory goes back to my Mk4 which had 225/45 17 on and then went to 225/40 18s to maintain the correct rolling radius.
