Ford Focus>> Wheels and tires>> Replacement of wheels>> Check of a condition of tires
Forward wheels are most loaded, therefore they wear out quicker, than back. Regularly look through a condition of forward wheels — best of all at the lifted car.
Check of a condition of tires carry out in the following sequence:
- completely turn a wheel and remove stones and other foreign particulates from working surfaces of the tire. If on a tire surface already costs a fragment of glass or a nail, in this case the tire the expert, should look even then when air does not leave;
- pay attention to damages, such as traces from pricks, cuts, risks and the torn cord. Even at small damage which it is difficult to define visually, moisture can get in the tire. The expert let will check;
- depth of drawing of a protector on all working surface of the tire should not be less than 2 mm. Depth of a residual profile on other sites of the tire measure similarly. Where on a lateral surface there is «twi» designation, it means existence of the indicator of wear of a working surface, depth of drawing of a protector cannot be less than 1,6 mm, you should replace that hour the tire as the behavior of the car on the road with a worn-out protector considerably worsens, in particular on a wet covering. Replace summer tires already at height of a residual profile of 2,5 mm. Winter tires lose coupling qualities already at height of a profile of 4,5 mm.

Check uniformity of wear of all tires. Look on lateral face of the tire: camber — the obvious certificate of the damaged framework (fig. 329 and 330) .
