I posted this in the BMW thread but anyone know if its ok to put non-spec tyres on BMW? Looking at Contact 7s which have Maserati "MGT" on them. Dont really want PS4S as the contacts are better, just upgrading from 20 to 21 wheels on the 640d.

I emailed Conti and they said:
The MGT tyres are dedicated for Maserati, normally you should not have an issues if all 4 tyres will be changed, however the tyre specification is select by the vehicle manufacturer not ourselves I’m afraid. Therefore I would strongly recommend to contact with BMW technical department to confirm this fitment (especially if your car came with SSR tyres as an original equipment).
No point asking BMW, they'll just say buy whatever brand they're promoting these days or PS4S
That is of course in my opinion. Under the core it is still very much a Conti SC7.
