Can you put 18" 215's all round onto a X5 with 19" 255 front and 285 back, the wheels are BMW but off another non sport model. Was going to use as winter tyre set up. Any advice welcome. Thanks
My 2004 X5 had 17" 70 profile 235s on all winter so you should be fine with the 18s. Check the price of tyres first though! Not sure about the newer model.
