3.18. Check of a condition of tires and pressure of their rating

Tires and the rims suitable for use on the car, and also pressure of a rating of tires, are specified in on шильде, B fixed on a rack from the driver.

Examples and possible causes of wear of tires

 PERFORMANCE ORDER

  1. At a sports manner of driving it is recommended to increase pressure in tires by 0.3 atm, proceeding from a base-line value for various conditions of loading.
  2. Winter tires, as a rule, have pressure upon 0.2 atm above, than summer. It is necessary to consider recommendations of manufacturers of winter tires, and also to remember, such tires have restriction till speed.
  3. Regular check of a condition of tires will allow to avoid the troubles connected with stops in a way because of the lowered wheel. Besides, such checks give valuable information on possible problems with a steering and a suspension bracket before emergence in them serious damages.
  4. Tires applied on considered cars are equipped with the built-in strips of indication of wear of a protector which are bared at decrease in depth of a protector to 1.6 mm. At emergence of the indicator of the tire are considered as the worn-out. It is in most cases recommended to replace the tires, which depth of a protector less than 2 mm. It is also possible to determine depth of a protector by the simple and inexpensive adaptation known under the name of a measuring instrument of depth of a protector.
  5. Pay attention to any unusual wear of protectors. Such defects of a protector as cavities, cambers, uploshcheniye and stronger wear on the one hand indicate violation of corners of installation of wheels and/or wheel balancing. At identification any of the listed defects it is necessary to address for their elimination in a shinomontazhny workshop (see an illustration Examples and possible causes of wear of tires).
  6. Carefully check tires on existence of cuts, punctures and got stuck nails or buttons. Sometimes after a tire puncture a nail it still some time holds pressure or lowers very slowly. At suspicion on existence such “a slow puncture” at first check tightness of a nipple of a rating of a wheel. Then examine a protector on presence at it got stuck strangers of subjects or eliminated before the punctures which have started over again to pass air. To make sure available a puncture it is possible, having moistened a suspected site with soap water. In the presence of a puncture solution will start to bubble. If not too big, the tire it is possible to repair a puncture in any shinomontazhny workshop.
  7. Carefully examine internal lateral surfaces of tires on existence of signs of leakage of brake liquid on them. If those are available, immediately check brake system.
  8. Maintenance in tires of the correct pressure increases term of their service, helps to save fuel and improves the general comfort of movement. The manometer is necessary for check of pressure.
  9. Always check pressure on cold tires (i.e. to a trip on the car). If to check pressure on the warm or warmed-up tires, it will lead to overestimate of indications of a manometer because of thermal expansion of tires. In this case it is not necessary to lower pressure since after tire cooling it will appear lower than norm.
  10. For check of pressure of a rating of the tire remove a protective cap from a nipple, then densely press to the rating gate a nozzle of a manometer and consider instrument reading – it should correspond to requirements of Specifications (see. Head Suspension bracket and steering). Do not forget to establish into place a protective cap for hit prevention in a dirt and moisture nipple. Check pressure in all tires, without forgetting about a spare wheel, and if necessary pump up them.
  11. At strongly expressed wear of forward wheels it is recommended to change them in places with back wheels.
