And F30 has taller tyres.
I'm a bit puzzled about the offsets being different though - I thought they had to be the same?
Or do the offsets differ depending on the wheels that the car comes with? To be honest though I don't really understand what the offset measurement really means.
Regarding the mounting specs, it sounds like you're saying that the info on the website is wrong?
As for the tyres being taller, do you mean the profile is bigger? IE the /xxR figure? (eg /45R or /50R)
