Check conditions before and during the test drive
Check all front and rear suspension components for damage.
Check and, if necessary, correct the air pressure in the tires.
Check tires for external defects. Punctures, cuts, sidewall bulges, localized wear due to lock-up braking and/or tread damage.
Find out if the tire has had a puncture, such as a nail or similar damage, and if it has been repaired by a tire dealer. If such tires are present, they should be replaced.
Check all tires for even wear and tread depth.
Determine if all tires are of the same type, model and have the same tread pattern.
For tires with non-directional tread patterns, make sure that all DOT markings are on the outside. The vehicle may have had tires or wheels replaced before.
We are talking about the types of tires approved by the factory for assembly by the manufacturer.
For a test drive, use a flat, straight, non-sloping road with no ruts.
Carry out a test drive, taking into account all the above conditions.
Note: There should be no strong side wind at the time of the test drive.
Note: Before starting work, you must read the following instructions, otherwise labor costs may be in vain.
Note: Before the first repositioning, mark the tires/wheels, for example, PL, PP, RL, RR.
After rearranging the wheels or changing the direction of the tire on the rim, observe the behavior of the car during a test drive. Note which tires and/or rims have been changed.
In this case, the intensity or change in lateral slip should be determined.
At the same time, test drives must be carried out by one master and on the same section of the road. Better drive «test plot» round trip.
Replacing a tire with a new one does not eliminate side slip. It is therefore recommended that you first purposefully rearrange the wheels as described below.
If there is a large difference in the tread depth of the tires on the front and rear axles, tires with a larger tread depth should always be mounted on the front axle.
