Once the tires are the only point of contact of a vehicle with the road surface, no one needs to say anything more about it how necessary it is for them to be in the ideal state.
However, except from damage and “defects” arising from the everyday use of the vehicle, there are also defects which “accompany” them from the moment they were manufactured… and so be it brand new.
A tire rarely – if ever – is 100% “weighted” and completely round. They don’t have it perfect shape nor her ideal weight distribution. And these defects come to point out the red and yellow dots which meet at their specific points and are very useful in the balancing process.
THE yellow dot she is the one who indicates the lightest point of the tire. Thus, to address the specific defect, it is recommended that the specific point of the tire be placed next to the rim point in which the valveas this is the heavier point of the wheel.
On the other hand, red dot shows the point at which the tire is flatter, as there is no all-round tire. It usually indicates the highest point of. Many times and the rims have a matching dot or some other kind of marking that “marks” it lowest point and it is recommended that these two points be placed together.
However, when on a tire there is both a red and a yellow dot and on the rim there is no associated dot or indicationthen the red “exceeds” yellow and this should line up with the valve stem.
In any case, however, the tire dots are a very useful indicator so that the craftsman in the vulcanizer, with the help of the proper machine, can to recognize the point where the imperfection exists and place the appropriate ones counterweightsto get the best result.
The usefulness of the specific dots is great, so that in daily use there is minimizing vibrations while driving. In this way, other systems of the vehicle are not burdened, such as suspension or the steering system.
