The most common cause is tire out of balance. Have your tires balanced and rotated. They will also uncover a bent wheel if that is the problem.

Tires and/or wheels may be out of balance
Striking a curb, hitting a pothole at higher speeds. Defective Tire. Striking a curb, hitting a pothole at higher speeds.
Stereo interference?
Sound speeds up when the temperature rises because the molecules in the medium vibrate faster due to the increase in thermal energy. This results in a higher velocity of sound waves through the medium.
well... there are many different causes for vibrations. The most common cause for steering wheel vibration at high speed is poor wheel alignment.
could be a blockage in your fuel lines.
Your steering wheel will vibrate at higher speeds due to either wear in your front tires or improper balance of tire pressure. IF these are not the promblem look to see if there is damanage to the shaft under the vehicle between the tires. Look at it or get it looked at before it gets worse, believe me I know how expensive it can be later!
The resistor block or blower motor resistor is used to control the speed of the blower motor. That is how you get the lower speeds on your air conditioning or heater. The higher the resistance the lower the speed of the motor.
why is my 1991 Mazda truck surging at higher speeds
It could be one of the following: 1. Tires are out of balance, 2. Perhaps one or both tires may wobble. 3. Brake rotors may have warped.
