Recently I have noticed the car seeming to tramline badly, which could could be related to my previous issues, I had the tracking checked, but it was within spec, however when the garage checked their data base it showed the pressures should have been 46/4 psi, they inflated to this as a trial and it seemed to run true, anyone use these pressures, they seem excessive, and make the ride even worse.
The car had now done 21k, and I changed the rear tyres to uniroyal rainsport 3's a few weeks ago, which improved the ride and noise levels over the bridgestones, the front tyres still have 5.5-6 mm but the tram lining was there before hand, is it a characteristic of the hard bridgestones once they are half worn?
At the moment the car is not pleasurable to drive, I need to get these issues sorted.
