The reason I had tracking done is because I had two new tyres fitted and all 4 wheels balanced, and it had been 50,000 miles since i got new tyres.
My mechanic told me to get the tracking done and I has read that you should get the wheel alignment checked.
Whether thats right I dont know.
I'm not sure whether I am over analysing the tracking anyway. Like I say when driving most roads on the left hand side slope to the left slightly and I am having to hold the wheel 5-10 degrees to the right but is that normal (to counter the slope)
If I drive on the middle of a clear road, which is more or less level it seems as though the steering wheel is straight.
