14.17.2. Tire whims

GENERAL INFORMATION

In use the car there is a wear of a protector of a tire which can be divided on normal and abnormal. Wear is considered normal if the small resource of a protector is caused not by existence of any mechanical defects in this vehicle, and grows out of service conditions.

Normal wear can be caused:

      â€“ a condition, a profile and road planning (on a mountain serpentine wear is twice higher, than in normal conditions);
      â€“ in the speed and rigidity of a manner of driving;
      â€“ ambient temperature and climate;
      â€“ engine capacity;
      â€“ compatibility of type of the tire with service conditions.

Abnormally fast wear is caused by defect or deviations from norm in a vehicle suspension bracket, system of a steering or brakes. This type of wear has an inclination passing on the one hand on another. Abnormally fast wear is shown in the form of a soskoblennost which is looked through within all protector, and also in the form of more or less appreciable wavy wear appearing on one of end faces of the protektorny block. It is caused by that moving of a wheel does not coincide with the plane of its rotation. If there was a non-uniform wear of the tire, it is necessary to check the following:

      â€“ pressure in tires;
      â€“ correctness of installation of wheels;
      â€“ adjustment, including the back bridge;
      â€“ balancing;
      â€“ to check a mechanical condition of the car: bearings, plugs, springs, ends of route drafts, pins.

The tire with unilateral cone-shaped wear on an equal flat surface slides with withdrawal as it happens when on the plane the cone slides. Only symmetry of tires on the right and at the left (let even strongly worn-out) relieves of such withdrawal. In what a mistake? That replacement of one wheel by another was made without any system.

If wheels on the car did not interchange the position, the picture of wear remains approximately to symmetric rather median plane of a body, and the car is quite acceptable heads.

The majority of automobile instructions contains instructions on in what terms and in what order it is necessary to interchange the position of wheels that their wear remained rather uniform. Tires with the directed drawing of a protector (having on боковине to the shooter "the rotation direction") demand still bigger attention. Here the replacement scheme according to the instruction is absolutely unacceptable – it is possible to interchange the position of only forward and back wheels of one party (left, right). Otherwise tires it should in addition перебортировать – who will begin to do it?

As you can see, even use of identical tires not always guarantees normal behavior of the car on the road. And different in a standard size, a design, protector drawing and so on? In these cases you can face various "surprises".

We already repeatedly wrote about the factors having an adverse effect on a tire, and also how to prolong life to the tires. Now you are given opportunity personally to be convinced of it.

Run on the lowered wheel

      â€“ fast leakage of air (cuts, wrong repair or installation);
      â€“ long driving after a puncture;
      â€“ very low pressure in the tire

Non-uniform wear (unilateral wear)

      â€“ wrong adjustment of wheels;
      â€“ untimely shift of wheels


Non-uniform wear (wear spot)

      â€“ sharp dispersal braking;
      â€“ faulty brake system;
      â€“ faulty suspension bracket;
      â€“ excessive adjustment of a disk and tire;
      â€“ untimely shift of wheels

Non-uniform wear (edge wear)

      â€“ untimely shift of wheels;
      â€“ faulty suspension bracket;
      â€“ sharp dispersal braking;
      â€“ the wrong pressure in the tire and / or an excessive overload

Otsloyeniye

      â€“ the wrong pressure in the tire and / or an excessive overload;
      â€“ excessively high speed

Cut of a protektorny part

      â€“ external cuts (from sharp stones, nails, bolts, flew down
etc.);
      â€“ careless driving

Porez-otsloyeniye protektorny part

      â€“ the otsloyeniye between protektorny rubber and a cord of breyker weakens because of external cuts, grooves from stones;
      â€“ an elevated pressure in the tire and an overload

Cut gap

      â€“ a gap because of external cuts or blows;
      â€“ an elevated pressure in the tire and an overload;
      â€“ careless driving on high speed

Cuts from a disk

      â€“ faulty disk;
      â€“ an inappropriate disk on the size

Attrition from a disk

      â€“ faulty disk;
      â€“ an inappropriate disk on the size;
     â€“ insufficient pressure in the tire and an overload;
     â€“ sharp or abnormal braking, dispersal, performance of turns;
     â€“ untimely shift of wheels

Ozone cracks

      â€“ the wrong storage, ozone influence at storage on the sun or near heatelectrogenerators;
      â€“ long storage;
      â€“ excessive deformation боковины because of an overload or low pressure

Lateral cut

      â€“ external cuts (from borders, sharp stones);
      â€“ careless driving;
      â€“ excessive deformation боковины

"Hernia"

      â€“ swelling on боковине (the localized blow causing an otsloyeniye
between elements боковины or framework);
      â€“ careless driving
