When I bought the latest Z4 in Sept 16 I was able to get a cracking good deal on the winter wheels and tyres from BMW - It was too good to miss. The 335 is our only car during winter and MrsK uses it and as we live at the bottom of a nast climb out to the main road, she really needs all the help she can - so winters it has to be if not for the pshycological help.
As an update on the £15 charge, I asked at another tyre retailer and he said that he would charge £10 / corner to remove and refit!
Guess who's not getting my business?
