Cheers SixDegrees, I don't really want the hassle of lowering my car (and to be honest can't really afford it any time soon!) so if I got 18" wont the car sit too high and be 'tractor' like on the stock TDI suspension?
I reckon my mate was talking about when the car is fully loaded with passengers and luggage he's saying it would rub with 17", is he still chatting out of his arse?
Aye, your mate is still uttering pish!!! As yours isn't a Sport version (assumption) then yes it might look a bit raised with 18" but this is more an optical-illusion as the overall diameter of 15" with right size tyres and 17" or 18" will only be a few mm different.
Now, working back from my 225/45 R17", I orginally had 205/55 R16" 2005 GT TDi 4Mos came with 16") and if I had 15" I would've had 195/65 R15" tyres.
So, if you have 15" I'm going to assume it may very well be 195/65 R15". Therefore...
205/55 R16" - 2.6mm smaller in diameter on new tyres, and
225/45 R17" - 0.2mm (yes, 0.2mm) smaller in diameter on new tyres.
225/40 R18" - 2.7mm larger in diameter on new tyres
Given that tyres operate between 8mm and 1.6mm of tread , ie 6.2mm or 12.4mm overall diameter in difference from new and legal limit, then 225/45 R17" will be nigh on exactly the same apart from width as what you have just now in terms or ride height / stance, its the fact that there is more gap in the alloys and less tyre between the alloy and wheel arch that gives the impression its riding high, the fact is the tyres are the same height.
