So after getting hold of a set of Michelin Alpin winter tyres and a set of 16s, I stuck them on the car on Sunday. Not a moment too soon as it was snowy already when I put em on. Havent really tried them out properly in the snow yet, as Ive had to take the girlfriends E46 Touring to work and dump my summer 18s off. But the one thing I did notice was how bloody comfy the Z4 rode with 16" wheels on!! Going to be tricky stickin the ellipsiods back on come springtime!!
