Yesterday I bought my V60 a set of new winter complete wheels (Hera 16″ 215/55R16 with Nokian WR D4) and installed them today. I was of course prepared for the RDK to report because it is hardly to be expected that the tyre pressure corresponds to the calibrated value of my summer tyres. That was also the case. So far so good. At the tank first before calibrating the air pressure all around. All tyres had 2.9 bar. 2,4 or 2,8 bar have – depending on whether under or over 160 km/h is driven, or depending on the load. Why are finished wheels delivered with 2,9 bar ? Please don’t misunderstand. I don’t want to cause a storm in the water glass here, but find that strange. Apart from that: How do you handle this with the tyre pressure ? I am currently driving around with 2,6 bar. So as a compromise between safety and driving comfort, since I am currently driving neither full pipe (now with the Wi nterreifen would be anyway at 210 end), still use the payload fully. Complementary question: Do you drive your winter tires with pressure other than the summer tires?
