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.
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, 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 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.
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) Check and adjust pressure. Central wear Excessive pressure Check and adjust pressure. Uneven wear Wrong disorder or выбег
