I'm thinking of replacing my S-max 18" ST wheels for a 17" set with a bit more rubber to give a less harsh ride.
I know a lot of people go the other way and I like them but the kids & wife find them to 'bumpy"!
The question is I know that the tyres should always be XL tyres but what about the wheels? I've heard and read that people say 'other' wheels won't be strong enough for the s-max and you need XL wheels as well? I have looked long and hard but can't find anywhere details of different strength alloys that are s-max rated etc.
Also many sell wheels as s-max compatible but they are from smaller cars, Focus, mondeo etc. Who is right and where can I find out more info?
