not usually, its so subtle its barely noticeable to the eye. they use laser guides to check it. trouble is usually as soon as u get it re-aligned the next pothole u meet knocks it off again! i tend to live with it, altho i might get it checked out when i put these new tyres on.
anybody get their tracking done regularly? how often? i feel the cost of doing it pretty much outweighs the premature wear on the tyres, altho that depends how bad it is and how expensive ur tyres are!
