OK so not the most accurate / scientific test in know but here you go: RED Denotes the values after a 22min drive along country lanes for 12 miles.
Ambient temp (as per car reading) 36 degrees
38 DegreesTyre temps - I sat the car in the warehouse to get them fairly even as it was sat in the sun and one side was 38 degrees!!

43 43Initial thoughts were a definate decrease in ride comfort, almost seemed a little crashy over bumps / drains that dont usually cause any more than a bump. Once up and running though i quickly forgot about it and concentrated on the 'feel' of the car. first real corner and the car did feel very different. Where before the rear felt almost floaty, this time it tracked round like it was real wheel steer. Similar high ish speed sections (approx 65 / 70mph) that has clear sighted winding corners gave a feel of sure footed control.
Although this was a very short drive and impossible to give a definative verdict i would say that on my particular tyre, the reccomended perssures from VW are a little low.
Hope this info is useful to someone
