Hello, I drive a BMW 320xd (E91) with 147 kw, which winter tyres can I drive on the BMW rim158? could someone please help me, I have the BMW rim 158 mounted on this are tires with 225/45 R17 94V. In the COC stands: 1/2 225/45 R17 91W, which tyres can I drive now? Unfortunately, the tyre dealer could not answer this question ?? Original on the rim are Bridgstone Blizzak LM25 225/45 R17 94V XL (RFT). I thought of the following tyres with BMW star:Conti TS830 P SSR 225/45 R17 91H Conti TS810 S SSR 225/45 R17 94V May I drive both tyres, or should I take the first breath of Bridgstone. If the COC 91W is available, can I drive 91H? Thanks for the support Jörg
