GENERAL INFORMATION

"Some motorists do not interchange the position of a wheel at next THAT is through 10 thousand kilometers of a run (as the instruction demands), claiming that it gives nothing. Whether they are right?"

Both options have the advantages and shortcomings. Tires on any car wear out unequally and unevenly. It is caused by its design (for example, conducting and operated are loaded more), technical condition of a suspension bracket (saylent-blocks, springs, shock-absorbers) and other reasons.

That tires (including "spare wheel") in use wore out at the same time and evenly, manufacturers recommend to interchange the position of wheels at everyone THAT, that is through 10–15 thousand kilometers of a run. However each tire, getting on the new place, at first it is earned extra, and it not always passes without consequences. Let's tell, at it external paths remained better. Having risen to the place of that where the same paths are more worn-out, it will quickly wipe the as they will be loaded at first is stronger than worn-out internal. Similar extra earnings of tires "eats" that the most part of a resource (hodimost), than technical condition of the car, first of all is worse than a suspension bracket.

Besides, after repair of a running gear or adjustment of disorder convergence of wheels will stand on hind legs of wear of the tire remaining on the old place whether something changed here.

Considering all this, skilled motorists interchange the position of tires through 25–30 thousand kilometers of a run, that is one-two times before failure. In this case it is possible to replace (and to buy) not at once all set of tires that suits many. As for the general hodimost of a set, in the second option its size usually is more.
