Thanks for the info guys. I'm not that much of an aggressive driver except for an occasional spirited run. It's an e46, RWD so shouldn't the rear shred? The pressure tag states
Unloaded
front: 32rear: 38and for a more under load setup:front: 38rear: 45
So I went for an average. I guess it's tire age then. Tie rods are ok, checked. Shocks are new. As I said, aligned every 5k. Time to fork out some cash for new rubber :'(
