Hello, now that I’ve fallen on my nose with my wheel change, I’d be interested in how other 7xDrive drivers can handle mixed tires. I had bought the M double spokes 303 in 20 inches for my 740d xDrive and was so naive to believe that I could have any tires fitted with the corresponding specification (size, width, carrying load), in my special case a Continental Sport Contact 5P without ROF and with MO marking. Unfortunately, I had to find out very quickly that my 7s is not compatible with every tire model or even can be driven by two special tires. BMW recommends in the dimension 245/40 R20 front and 275/35 R20 back either the Pirelli P Zero or the Goodyear Excellence, both with ROF and star marking. I’m not sure if I should do another tyre test on these rims. I’m afraid that it won’t work again and I’ve wasted a lot of money again. On the other hand, you can order this rim from the factory, so they should work in every case. How are your Drive Mixing Greetings and X Drive?
