I found the same problem and was told that the tracking would be better set to " ?????" (cannot remember off hand). There has been a few postings, so do a search and you should find it. I have not had the 7 on the road since I was told this (back, end of next week) so I have not proved it yet!!!
Especially bad when tyres were cold. I don't like the 888's so far, think the Yoko's were far better.
