As I mentioned yesterday, tire wear especially with the cross-sectional stepping one is a good index to know the actual condition of wheel alignment and constructive axle geometry. Excessive toe in value invites outer side inconvenient wear on the tire tread surface for rear wheels, uneven wear shows some thrust discrepancy, on the other hand, too much outer direction of toe value on frontal wheels does outer side. But, remember here, all of 4 wheels interact with each other with balancing condition. Anyway, strange steering reaction while driving an automobile would encompass any error in wheel alignment and axle constructive geometry. Careful checking and actual scaling of constructive error reveal the result of the cause exactly as usual. Physics never tell a lie.
