Check conditions to and during a trial trip

Check all elements of a suspension bracket of a lobby and a back axis on existence of damages.

Check and if necessary modify pressure of air in tires.

Check tires on existence of outer defects. Punctures, cuts, swellings on боковинах, local wear because of braking with the blocked wheels and/or protector damages.

Whether find out there was in the tire a puncture, for example, the nail or similar damages and whether made repair at the dealer of tires. In the presence of such tires it is necessary to replace them.

Check uniformity of wear and depth of a protector of all tires.

Establish, whether all tires of one type, model and have identical drawing of a protector.

At tires with not directed drawing of a protector check, that all designations of DOT was outside. Probably, on the car replacement of tires or wheels earlier was already made.

It is a question of types of the tires allowed by plant for a complete set by manufacturer.

For a trial trip use equal, direct, not the inclined road without a koleynost.

Execute a trial trip, considering everything the called conditions are higher.

NOTE At the moment of a trial trip there should not be a strong lateral wind. Before the beginning of works it is necessary to familiarize with the following instructions, otherwise labor costs can be vain.

NOTE Before the first shift mark tires/disks, for example, PL, software, ZL, ZP. After shift of wheels or change of the direction of the tire on a disk it is necessary track behavior of the car at a trial trip. Mark, what tires and/or disks перестанавливались. Thus it is necessary to define intensity or change of lateral withdrawal. Thus trial trips should be carried out surely by one master and on the same site of the road. It is better to pass «a test site» in both parties.

Replacement of the tire by the new does not provide elimination of lateral withdrawal. Therefore it is recommended to rearrange purposefully at first wheels as it is described below.

At a big difference in the heart of a protector of tires on forward and back axes, tires with bigger depth of a protector should be mounted always on a forward axis.
