Did 3000 in 2 weeks around Europe. Took a tyre pressure gauge to check them at food/fuel stops and that was it. Car was faultless. 
Driven Poland to Tewkesbury (or Tewkesbury to Poland) in one go many times. Just over 1K miles takes 18hrs with ferry. Driving will be easy till u get out of Germany. Roads ain't great in Poland and Ukraine, mostly A roads through villages etc. Not many motorways. Tricky to overtake slower stuff, lorries, tractors, donkeys etc, coz your on the wrong side of the car to see what's coming
