We have always been told about maintaining the correct tire pressure to save fuel. It is a truth of a fist, but probably not the most important, it turns out that at the moment of truth, and of safety, the first effect of a tire with more or less air than the errand is that its grip on the ground decreases because the tread pattern is not full.
It rests more on the edges if it is low on air or in the center if it has been overinflated, and this in turn does not depend on the tire, but on the vehicle that uses it, since these pressures are determined by its weight and geometry of the tires. suspensions. Hence, the pressure to use is what the manufacturer says and not the mount.
But we are going to save gasoline, vital in these days when it is becoming unaffordable. A low pressure tire increases consumption because it drags more against the ground, which does not happen if it is highly inflated.
Beyond the air that is put into it, the tire influences the proportion to the resistance that its tread and structure presents to advancement or rolling. That resistance is the amount of energy that the tire consumes to make it move a certain distance.
There are several factors that act against it: the force of gravity, aerodynamics, inertia and mechanical friction. These are modified by the compound of the rubber, the design of the casing and belts, the distribution of the weight of the vehicle, the roughness of the road and the weather.
There is one more incident called ‘hysteresis’, which is reported by Continental, but it is common to all tires. It is the deformation that occurs infinitely when the tire rolls when it touches the ground. It is crushed and that movement is absorbed by the tilling that rubs against the road, and there the rubber compound is vital to affect the resistance that it generates when moving forward.
It is very difficult, if not impossible, to decide by eye which tire is more efficient, especially when the treads may be more indicative of the ability to disperse water on puddled ground. Let’s remember that only a percentage of the width of the tread is used, since the grooves are necessary, but at the same time it reduces the amount of rubber that is effective in the grip.
In other words, the more studs, the less real band there is, and for the sample the tires of the competition cars that are smooth. Therefore, the carving blocks, their arrangement, separation, height and flexibility affect gasoline consumption, but the only way to know is by referring to studies of the brands, their seriousness and background and knowledge.
Because an ad proposing benefits in grip, braking, more safety in the water, resistance of its parts and duration will always be easy, but between the saying and the result there is a long way that can cost more than necessary.
