Newbie.....to V40s anyway
 

Hi

I'm just in the process of scrapping my beloved C30 D5 and buying a V40 D2 replacement.
I know, what a climb down. But need must, and was wondering, could I fit my C30's 17" alloys onto the V40 that have Uniroyal RainSport 5 - 225/40 R18 92Y fitted?

I think the V40 has 16" fitted just now, but not sure of the tyres

Thanks

Think carefully (are your wheels 17 or 18?) it might slow down a car which will already feel significantly slower than your C30.

If the outer diameter is the same, can it slow it down?
Or is it to do with width?

If the OD is the same then you should be ok.
