Check of a condition of tires and pressure in them

The BMW car of the 5th series depending on model and the equipment has tires and disks of various sizes. Along with disk width important parameter is also its departure. The departure represents distance between the longitudinal plane of a disk of symmetry of a rim and the fixing plane of a wheel.

All disks have the so-called hampa representing a belt, vypressovanny on a rim of a disk and interfering the shift of the tubeless tire at abrupt turn of the car.

At installation of the tires and/or disks which are not specified in technical documentation the car it is necessary to make the corresponding records in documentation. For this purpose, as a rule, permission of BMW is required.

The tires and disks recommended for BMW are given in Specifications.

Regular check of a condition of tires will allow you to avoid the troubles connected with stops in way because of the lowered wheel. Besides, such checks give valuable information on possible problems with steering and a suspension bracket before emergence in them serious damages.

Tires 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 then tires are considered as worn-out. This size represents minimum admissible depth of a protector; it is in most cases recommended to replace the tire which depth of a protector of 2 mm and less. Depth of a protector can also be determined by the simple and inexpensive adaptation known under the name of the measuring instrument of depth of a protector.

Pay attention to any unusual wear of protectors. Such defects of a protector as cavities, cambers, flattening and stronger wear on the one hand indicate violation of angles of installation of forward wheels and/or balancing of a wheel. At identification any of the listed defects it is necessary to address for their adjustment in a tire workshop.

Carefully check the tire for existence of cuts, punctures and the got stuck nails or buttons. Sometimes after piercing of the tire a nail it still some time holds pressure or lowers very slowly.

Poddomkratte the car also spray soap solution on a protector, slowly turning a wheel - in the place of a puncture small bubbles will appear

At suspicion at first check tightness of the nipple of the gate of a rating for existence of such "slow puncture". Then examine a protector on presence at it of the got stuck foreign objects or punctures which are closed up earlier which started over again passing air. If there is a suspicion that there is a puncture, it is possible to make sure of its existence, having moistened the suspected site with soap water. In the presence of leak solution will begin to bubble. If a puncture not too big, the tire it is usually possible to repair in any tire workshop.

Carefully examine the internal side surfaces of tires on existence of signs of leak of brake fluid on them. If those are available, immediately check the brake system.

Maintenance in tires of the correct pressure increases the term of their service, helps to save fuel and improves the general quality of driving. The special manometer is necessary for check of pressure.

Always you keep the exact manometer in the ware box. Indications of the manometers which are built in nozzles of air hoses at stations of service often happen inexact.

Always check pressure on cold tires (i.e. to a trip on the car). If to check pressure on the warm or warmed tires, it will lead to overestimate of indications of the manometer because of thermal expansion of tires. In this case it is never necessary to lower pressure since after cooling of the tire it will appear below norm.

Check air pressure in tires once a month, and also when carrying out THAT. The table with the indication of pressure of air is on a rack of a door of the driver and in Specifications.

To prolong service life of tires, check pressure in them at least once a week by means of the exact measuring instrument (do not forget about a spare wheel!)

Screw together a protective cap from the gate of a rating acting from a disk of a wheel or from a nave cap then densely press a manometer nozzle to the gate. Consider instrument readings and compare them with recommended in Specifications. Do not forget to install into place a protective cap for prevention of hit in the mechanism of the nipple of dirt and moisture. Check pressure in all four tires and if necessary pump up them to the recommended value of pressure.

Do not forget to support the required pressure and in a spare wheel.

Examples of characteristic wear of protectors of tires

Side wear

Insufficient pressure (wear on both sides)

Insufficient pressure in the tire leads to its overheat at the movement owing to an excessive deflection therefore the protector does not nestle sufficiently on the surface of the road. It leads to loss of coupling with the road and to excessive wear of a protector, not to mention danger of an exit of the tire out of operation as a result of an overheat.

Check and adjust pressure.
Wrong disorder of wheels (wear on the one hand)
Repair or replace suspension bracket details.
Too sharp turns
Reduce speed!

Central wear

Excessive pressure

Excessive pressure in the tire results in the accelerated wear of the central part of a protector, decrease in coupling with the road, more rigid movement and increase of danger of fatal damage of a slope.

Check and adjust pressure.
If you had to pump up tires for transportation of heavy freights to the value of pressure specified for this purpose in Specifications, do not forget to pit after that it upon transition to the normal mode of operation.

Uneven wear

Tires of forward wheels can unevenly wear out as a result of violation of adjustment of angles of installation of wheels. It is possible to check and adjust the angles of installation for a moderate payment in the majority of tire workshops.

Wrong disorder or выбег
Repair or replace suspension bracket details.
Defect of a suspension bracket
Repair or replace suspension bracket details.
Wheels are debalanced
Make balancing of wheels.
Convergence of forward wheels is incorrectly established
Check the angles of installation of forward wheels.

the obtrepannost of edges of a pattern of a protector which is a wear sign best of all comes to light наощупь.


Check of the gate of tires

 CHECK

1. Turn off a cap from the gate.

2. Wet with saliva a few gate. If at the same time the air bubble is formed, turn a zolotnik of the gate (3) the turned cap key (2).

Only the cap key can be applied to tightening of an insert of the gate (2). Such caps keys can be got at gas stations. 1 - a rubber protective cap, 4 - the gate.

If there is a suspicion that there is "a slow leak" tighten a gate 3 zolotnik the turned cap key 2

3. Again check the gate. If the vial of air is again formed or the gate is not wrapped, replace it (work HUNDRED).
4. Surely establish into place a protective cap.

Check of a protector of the tire and reliability of fastening of a wheel

 CHECK

1. Tires of the balanced wheels at observance of the established air pressure, the correct installation of wheels and the correct operation of shock-absorbers wear out evenly on all surface. To tell something certain about service life of tires of these or those manufacturers difficult since it depends on various factors, namely:
   -  Surfaces are expensive
   -  Air pressure in tires
   -  Management style car
   -  Atmospheric conditions
2. First of all sports management style, sharp start-off about places and strong braking are the reasons of more bystry wear of tires.

Rules allowed wear of a profile of the tire up to the depth of 1.6 mm, i.e. depth of flutes on all surface has to make not less than 1.6 mm. However it is recommended to replace for safety reasons the tire already with the minimum depth of a profile of 2 mm.

3. If depth of a profile comes nearer to minimum admissible, i.e. indexes of wear of 1.6 mm in size in many points of a circle of the tire show lack of a profile, tires need to be replaced. Indexes of wear of a profile are located on all circle of the tire. Address an accompanying illustration. Their arrangement is designated sideways by the inscription "TWI" and the sign "s". TWI - Tread wear indicator.

tires M + S (winter) are effective on slush and snow if depth of a profile makes not less than 4 mm.

The arrangement of indexes of wear is designated sideways by the inscription "TWI" and the sign "s". TWI - Tread wear indicator

Check existence on tires of cuts. Depth of cuts can be determined by the small screw-driver. If cuts reach a framework, then at water penetration it can lead to corrosion of a steel belt. As a result of it the working surface of the tire can separate from a framework and the tire collapses. Therefore in the presence of deep cuts the tire needs to be replaced.

4. For definition of wear of the tire use the protector depth measuring instrument - they are on sale in shops of automobile accessories and at stations of service, and cost very not much.

5. Tighten bolts of fastening of a wheel cross-wise the moment of 100 Nanometers. Do not oil bolts or lubricant.
