Can over inflated tires cause vibration？
Regarding the question of “can over inflated tires cause vibration”, let me tell you, 100% will! Do you still need to ask?
What kind of feeling do you think this vibration is? Well, the most direct feeling is that the car “jumps” when driving, especially when running at high speed or when the road is uneven, the steering wheel, seat, and even under the feet can feel that kind of subtle shaking, just like the car “bouncing” on the road, not “rolling” smoothly. particularly uncomfortable.
1.Why is this happening?
The principle is actually not complicated.
First of all, the contact surface must be small. If the air is too full, the tires will bulge badly and the contact area with the ground will naturally become narrower. The grip must be affected, and the stability of the car is almost meaningless. Isn’t this the root cause of the vibration?
Moreover, and most importantly, the shock absorption capacity is useless. The tire is not only used to grip the ground, it is also the “head shock absorption” of the car “. However, as soon as the tire pressure is high, the tire wall is called a hard one, and its elasticity is completely gone, just like a solid ball. Even if 1 is a pebble on the road, the impact will go directly to the suspension, to the car body, and finally to your ass and hands. It is not a “suction” shock, it is a “transmission” shock, what movement on the road, all shake out to you.
Also, the tire pressure is high, and the deformation of the tire itself is also wrong. Under normal tire pressure, there will be a regular “creeping” when the tire rolls, which is normal. However, when the tire pressure is high, the normal deformation will be restricted, but irregular beating or oscillation will occur. I tell you, sometimes the car shakes, don’t always think about whether the dynamic balance is broken, the tire pressure is high, the bumpy strength is more than the dynamic balance imbalance.
Therefore, tire pressure can not be underestimated. Its impact on your driving feeling is real and much bigger than you think.
2: Tire pressure too high?
That’s not just vibration so simple!
You don’t think that too much tire air is a bumpy spot, it’s no big deal. I tell you, this thing can really give you a lot of moths, is an “invisible killer”, 1 a lot of trouble is related to it.
Accelerated tread central wear:
This is the most common. When the air is full, the middle of the tire bulges, and the area in contact with the ground is mainly concentrated in the middle part. The time is 1 long, the tread patterns on both sides are still good, and the middle is almost smooth. This is not equivalent to shortening the life of the tire?
Grip decreases, affecting handling and braking:
The contact surface between the tire and the ground is small, and the grip must be poor. Especially when it rains or the road is a little wet, the risk of skidding goes straight up. During emergency braking, the braking distance will also become longer. This is not a joke, it is directly related to your life.
Increased risk of puncture:
Especially in the summer, or at high speed. The road temperature itself is high, and the internal temperature of the tire’s high-speed friction will also soar. If the tire pressure is still high, the internal pressure is simply “adding fuel to the fire”. At the moment, the tire is like a balloon that will explode at any time, and the risk of a flat tire is rising. I ‘ve seen a lot of flat tires because of this, and that scene, it’s killing me.
Decreased ride comfort:
The tire itself is the first 1 of shock absorption. When the air pressure is high, the tires will be hard. After a snag, the bumpy feeling will definitely impress you and the whole car will jump. After a long time, people will suffer.
Suspension system burden increased:
When the tire’s shock absorption capacity is reduced, the impact of the road will be directly greeted to the suspension system. The shock absorber, ball head, bushing and other parts bear greater force, and the wear will naturally be faster. What could have been used for a long time may have been scrapped in advance.
Part IV: How to judge whether the vibration is caused by high tire pressure?
If your car starts to shake, how can you tell if it’s caused by high tire pressure:
Observation method:
This is the most direct. Get out of the car and walk around the car 1 times, taking a closer look at each tire. If the air pressure is too high, you will find that the tire looks very full, even a little “bulging”, and the contact between the tread and the ground will appear very narrow.
Feel method:
Press the tire tread with your hand to feel the hardness. Tires with normal tire pressure are somewhat elastic. If the air pressure is too high, you will feel as hard as a stone and will not be able to press it.
Tire pressure gauge measurement:
Of course, the most reliable thing is to measure it with a tire pressure gauge. Now this stuff is not expensive, it is good to buy one and prepare it. Find a flat place to park your car, wait for the tires to cool down (hot tires will not be allowed), and then measure them one by one.
Control standard tire pressure:
After measuring the value, you need to know what the standard tire pressure of your car is. This information is usually on the inside of the fuel tank cap, on the driver’s door frame, or in the user manual. By contrast, if the measured value is too high than the standard value, then the tire pressure is too high.
To exclude other possibilities:
There are many reasons for the vibration. You can’t just stare at the tire pressure. If the tire pressure is too high, or the tire pressure is adjusted or shaken, then something else may have to be considered. For example, the dynamic balance is wrong, the wheel hub is deformed, the shock absorber is broken, or the drive shaft or half shaft has problems, etc. At this time, I suggest you go directly to the professional repair shop and let the technician check with professional equipment to find out the real root of the disease. After all, safety is no small matter.
3.Solution: Say goodbye to vibration and restore safe and comfortable driving
Immediately adjust the tire pressure: found that the tire pressure is high? Don’t talk nonsense, quickly transferred to the manufacturer’s recommend value for me! This stuff is usually attached to the edge of the driver’s door, or it can be turned to in the user manual. Don’t rely on feelings, that’s bullshit!
Regularly check tire pressure: give me this at least once a month, must form a habit! Before running at high speed for a long distance, it is necessary to check. Don’t be too troublesome. This is a life-saving job.
Choose the right tire pressure gauge: there are many tire pressure gauges on the market, but choose a reliable one. I personally recommend digital tire pressure gauge, accurate readings, it is also convenient to use. Unscrew the valve cap directly, and you can count it when you press it tightly.
Pay attention to the cold car tire pressure: remember, the tire pressure measurement must be in the cold car state! When the car runs, the tires become hot and the air pressure will rise. The data measured at this time is wrong and has no reference value at all. It is best to stop and wait for three hours, or when the car is not running much.
Follow the recommendations of the vehicle manufacturer: emphasize 1 times, the standard tire pressure given by the manufacturer is the most scientific and safest, not one of them! Don’t listen to those “old drivers” who are fooling about “running at high speed with higher tire pressure to save fuel”. If you believe their nonsense, you will suffer sooner or later.
Common Misunderstandings Clarification
Misunderstanding 1: Tire pressure is higher and more fuel-efficient?
In theory, a little higher tire pressure can really make the tire rolling resistance small so 1 to throw away, which sounds like it can save some fuel. But what about the reality? The little gas money saved is not enough for you to replace the worn tires later, not to mention the potential safety hazard in case of an accident. In my opinion, it is not worth it to risk one’s life for the sake of sesame’s bigger oil money.
Myth 2: high tire pressure tires look fuller?
This is all your delusion! The tire looks “full”, mostly because the tire crown is excessively raised. This so-called “fullness” is not a healthy performance at all, but will cover up the problems caused by high tire pressure, such as a smaller tire contact area and reduced grip. So, don’t just look at the surface, the data is the most real.
