Checking the condition of tires and pressure in them (every 400 km (250 miles) run or weekly)

Regular inspection of the tires can help to avoid trouble caused by an unexpected stopover associated with the descent of the wheel. In addition, the condition of the tires can provide valuable information about possible problems related to faulty components steering and suspension long before failure occurs.

Factory installed on the cars of this brand tires fitted half-inch (about 13 mm) control tape wear, which become visible when wiping up the tread depth of 1.6 mm. The degree of wear of the tread can also be determined using a simple and inexpensive device, known as the tread wear indicator - ask in shops of automobile accessories.

Pay attention to any abnormal tread wear. The presence of irregular tread defects, such as cavities, flattened areas, stronger wear on one side, etc. says abuse balancing or alignment of the front wheels. Upon detection of such defects characteristic tread drive away the car in a fitting center for correcting violations.

This card is the typical form of the tread wear will help you determine the condition of the tires of your car, presumably to establish the cause (s) and choose wear corrective measures

condition	possible cause	Action to eliminate the cause
Istrepyvanie edges of the tread pattern End wear	Improper convergence of wheels	Adjust convergence
Uneven wear	Incorrect camber or caster angle of the axis of rotation (coasting) wheels	Repair or replace components or the suspension bridge
	Defective suspension	Repair or replace suspension components
	An unbalanced wheel	Perform wheel balancing or replacement
	Roundness of the brake drum	Pierce or replace the drum
	Neglect of performing the rotation of the wheels	Make rotation of wheels

Examine them carefully to the presence on the tires for cuts, punctures, stuck in the tread pattern of nails and small stones. In some cases, the wheel after a puncture continues to hold the pressure because a nail stuck in the tire's own body plug hole. If a wheel starts to slow down on a regular basis, first check the condition and serviceability of the pump valve (nipple). Next, inspect the tread on the presence of a nail stuck in the puncture or other foreign objects, as well as the repair of defective corks (radial tires are often repaired by installing a special repair holes in traffic jams). If there is a suspicion of puncture, it can be easily checked with a solution of soapy water - after wetting the surface of the tire soap solution to the puncture site will appear bubbles. If the defect is not too extensive, the wheel can usually be repaired in the tire shop.

If the wheel is constantly slowly descend, first check the condition of the pin valve pump (in shops of automobile accessories can be purchased at high prices are not a special key).

Inspect the inner walls of each tire for the presence with them of traces of brake fluid. Upon detection of such instantly check the condition of the brake lines and gear.

Inflating the tires to the correct pressure can significantly extend the service life, as well as significantly improve comfort during movement. Correct pressure pumping wheel can not be reliably measured by eye, especially when it comes to radial tires. It requires a special gauge. Try to keep this in the glove compartment of the car. Do not trust the testimony of pressure gauges installed on the hose nozzle swap wheels petrol stations.

The pressure in the tires, always check with the cold wheels. This means that after the last use of the vehicle (when run-length greater than 1.5 km) must be not less than three hours. Increasing the pressure in the hot tire 0.27 - 0.5 atm. It is normal.

Remove the protective cap from the valve of the pump extending from the disk / hub and firmly press it to the nozzle pressure gauge. Consider reading device and compare the measurement results with the data on the nameplate of significant fixed to the front driver's door. Do not forget to screw in the valve cap in order to avoid falling into the nipple of dirt and moisture. Check the pressure in all four wheels, if necessary, make adjustments.

Do not forget to maintain the required pressure in the spare wheel (see. The data owner's manual or marked on the sidewall of the tire).
