Hi Folks - Long Time No See For those who don't know Elaine's car: 2002 Mk4 25J (Anniversary) - SACHS RACE ENGINEERING COIL OVERS 225/40 R18 I always fitted Dunlop MAXX RT AO, but recently switched to Pirelli P Zero SC AO XL. Running the Dunlops at the recommended 2.0 bar resulted in fairly even wear across the front tread. With the Pirelli tyres at 2 bar both front tyres are each showing massive wear on both shoulders. Of course this is an indication of 'Under Inflation'. I spotted it too late to experiment with higher pressures. Front wheel alignment is perfect. It has just passed the NCT so there is no wear in the front suspension. So. Has anyone else seen this phenomenon with other tyres? Is 2.0 bar front too low for the 25J? (My son's Mk5 ED30, with the same size tyres runs, 2.6 bar at the front but it is a chubby 78+ kg heavier then the 25J) The 25J is not supported very well with data. For example: The standard car is lower than any other Mk4 but neither the VW dealer nor I can find a figure for the correct ride height! Perhaps the tyres pressure for R18 wheels should be higher and, as with ride height, VW could not be arsed to do the job properly!? Any comments please. Regards, Dave. Interestingly. Mk5s run different pressures for identical cars with different size wheels.
