You can estimate a technical condition independently provided that tyres of forward wheels from one manufacturer, have an identical profile and pressure in tyres corresponds to norm. An estimation spend by following criteria:

- At movement directly the steering wheel should be on the average position, without any displacement;

- At movement directly on equal road after you have removed hands from a steering wheel, the car should not leave to the left or to the right;

- After end of turn the steering wheel should return to the position corresponding to movement "directly" independently;

- Non-uniform deterioration of tyres.
