The tires almost never wear out equallytires, being those of the front axle those that more accuse the passage of time and kilometers. This is due to the fact that most cars today are engine and front-wheel drive, which means that support more weight and wear. In addition, the friction in maneuvers from standstill also ends its useful life sooner.
Ideally, when these are changed, the rear wheels should also be replaced, but this implies double the budget when in fact the rear tires are still in an optimal state of use.
Si se van a change only the two wheels on one axle, the most advisable – not to say obligatory – is that the new tires are placed at the rear, for different reasons:
In an extreme situation, a car with an engine in the forward position you will always lose grip on the back sooner because it has less weight. To compensate for this difference, it is important that the newest tires and therefore with greater grip are always on the rear axle.
Once you lose control of the vehicle it is easier to bring the front part to the site in which we have the natural guidance of the direction, that the rear part, in which we should execute a not always simple counter-steering wheel to counteract oversteer. It is because of that it is advisable to have tires with better grip at the rear, to avoid loss of control in this compromised area.
BEST PLAYING IN FRONT
When the tire is worn it is easier to suffer a puncture. If driving at high speed it is better that this occurs on the front wheels since again it is easier to regain control of the nose than of the rear of the car. Consequently, it is always better to have less worn tires at the rear to avoid a puncture on this axle.
LOWER RISK OF AQUAPLANING
Aquaplaning is one of the most dangerous situations that we can suffer in a vehicle. It occurs when the tires are not able to evacuate all the water that is on the ground and a layer is created under the wheels that makes the car floats on the asphalt. The weight of the engine can counteract this situation on the front axle, but the lightness at the rear makes it necessary to have a tire with a good drawing to be able to evacuate all the water as possible.
All these tips would not work for a car with all-wheel drive, since a more worn tire has a smaller diameter and therefore turns more than the new ones in the same route. If in a 4×4 we change only the wheels of one axle we will be forcing the differential to work tirelessly to balance this difference and therefore subjecting it to greater wear that can lead to premature and costly system breakdown.
