I did not have my tracking 1/2 degree out as I previously said but parallel. This was on the outer limit of "out". I did this to eliminate scrubbing of the left hand side wheel which often occurs. Now after 10,000 miles the tyre insides are scrubbed very slightly. Yes Clive you can feel smaller imperfections by feel. Now I've set it to 24 minutes toe in it has been transformed. All tramlining gone. In fact I was able to watch a whole edition of the antiques roadshow without taking my eyes off the screen.
