Uneven tire wear

Tire wear has much to do with the establishment of wheel alignment and axle constructive geometry, no one would deny this opinion. The change of driving habit is often observed after the tire wheel rotation procedure, this phenomena shows the wear of tire treads have not been worn evenly. Of course it is caused by several reasons, the way of driving, burdened weight,etc.. Every tire tread wears in some specific physiologic circumstance including wheel alignment and axle constructive geometry promptly. So, the adjustment should be performed at the time of tire replacement into new ones, if desired, suspension bushes replacement.
Judging from my experiences in this field, at least 100 km distance running is necessary to forget and eliminate uneven wear of tread surfaces that had been followed. It's impossible to establish the alignment at only single attempt because of upper reasons, several times of adjusting performance would be required to minimize the assembly discrepancy on the factory producing line.
The physical condition is the same that even a mass production passenger's car has 4 wheels as an expensive luxury car, so, precise adjustment on the alignment would acquire the ultimate performance that would be done on latter one prior to the rolling out. As a conclusion today, my opinion like this is not out of the point at all.
We do not have any measurement equipment that are set in the production laboratory of factory in research and developing division, of course they must be expensive, exaggerated, professional authentic. And the ordinary car users do not know how to know the phenomenon, what kind of device and equipment are required to know the actual condition as a numerical datum, where to measure and what kind of  pitfalls and uncertainties exist on the way, but still insist I do it by myself.
