I am not sure My11 models they started using Michelin tyres.. Mine is Jan 2010 built My10 came with Yokkohama decibel.. I don't know its random they use michelin tyres... May be some others bought the standard euro recently can confirm this.
I just look at carsales website for standard model car tyre picture and this below 2010 My10 demo euro, if you guys look at the closeup tyre picture it shows "Turanza", this means the tyre is Bridestone.. Seems like for standard EUro they use mix bag of tyres, Yoko, Michelin, Bridstone, unlike they use Michelin only for lux models....
