No problem Mario and good luck trying to get a freebie. Also I forgot to mention that if you don't already have them you will need to carry a tool to remove the inner part of the valve and also a compressor or pump.
Picking up my X1 on saturday. The tyres are Michelin Primacy ( summer ones!). Strange choice of tyre for a 4 x 4 car. Any problems and I'll need to consider changing them.
