I guessed so but it didn't stop me having a chuckle at the mental picture of a BMW ploughing down screaming pedestrians whilst the driver complained about the chatter from the tyres 
Well yeah - BMW drivers are usually oblivious to other road users through their arrogance

Anyway, I am looking at 4x of the Vredestein Ultrac Sessanta based on the recommendation of you guys, what sizes do I need for the 18" monza2 wheels?
Cheers
