I would like to add this. The stated tire pressures are with cold tires. So in summertime (around +20 C), the tires will move up +0.2 Bar after just a few km of driving at 70km/h. When it gets below 0 C outside I need to add 0.2 Bar to maintain the cold tire setting of 2.6/2.4 Bar and it gets to 2.8/2.6 Bar after about 10-15km of driving (high-way speed).
So in short, with rather slow driving an increase of 0.2 Bar when filling up the tires is necessary to maintain the suggested tire pressures.
