Any advice please? Anybody experienced the same tyre/alloy wheel issues? We've owned X5s before and enjoyed them, but the latest X5 (M Sport with MV Spoke Style 227 M10/11J x 20)has had 13 punctures and now two cracked rear alloys in 22 months. This combination of wheel and tyre seems very unreliable. Most driving is on motorways. The alloy wheel is on 'back order' so there is no ready solution.
