Does tire pressure affect vibration?
When your right tire becomes under-inflated, its resonance frequency occurs at about 40 miles per hour. That natural vibration is combining with the unbalanced wheel to create a noticeable shimmy at that speed. Raising the pressure in that tire raises the resonance frequency, causing the noticeable shimmy to disappear.
What causes tires to vibrate up and down?
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts. Wheel alignment should also be performed at proper intervals.

Replacement of the damaged component (s), or professional wheel repair are the only safe solutions. If your vehicle has been sitting for an extended period of time, tire flat spots can be a cause of driving vibration. Tires are intended to be used.
What causes vibration when driving at high speeds?
Causes of Tire Vibration. Another cause of a vibration at higher speeds is uneven tread-wear. A tire that has been on a vehicle for a year more, more start to wear more on one side of the tire. This is not the sign of a manufacturing defect. More likely, the cause is a slightly mis-mounted tire.
Why does a flat tire make my car vibrate?
Tires affected this way are prone to damage and blowouts. Under-inflated tires quickly overheat and wear abnormally at the outer edges, leading to low and high-speed vibrations. In addition, rolling resistance greatly increases (think about pedaling a bicycle with a flat tire).
What causes a vibration in the steering wheel?
This causes the weight of the tire and wheel to be unequal from one side to the other, and the result is vibration which is felt through the suspension of the vehicle and up through the steering column to your hands on the steering wheel.
