Had a similar problem myself, got my new wheels fitted and got the tracking done at a local Hi-Q, seemed ok at first, then gradually started to pull to the right and wheel wasn't exactly straight when i was driving straight, as others said, petty but annoying.
So i took it back, they checked and and there was some kind of problem, i slightly overheard a conversation whilst waiting, after that they were ever so helpful. not exactly sure of the problem, but they said it was now sorted. but after driving down south and covering 550 miles in 2 days i am once again noticing the same, when i let go of the wheel it starts to move right, it doesn't pull that way, just goes that way, its ok under braking though.
the tyres are new so not that, wasn't sure if it was maybe the road camber, but in that case it should do it in both directions. Wonder if there is anything else wrong?
AndyMac- Where could i check for a tracking specialist, especially up north?
