Hello! I am currently looking for good used or new 205/50 R17. I bought the car recently used. On the current rims are 205/50 R17 93 W. I have to replace two of them. To my questions… My 325ti is registered with 235 km/h. The current tire is approved by the “W” up to 270 km/h. May I also raise “V” (240 km/h)? Next, I would like to know if I should also raise RunFlat tyres. Or do you need to use the vehicle license a n special indication? By the way, the rims are 7×17 R47 BMW Style 73.
