It's not the tires. This is how you eliminate the possiblity of tires being the cause of high speed shakes. It's in the drive train some where. What year, make and model and how many miles? Maybe cv shafts if it's a front wheel drive car......need more info.
ford mondeo no question about it the almer is always so stiff at low speed and vibrates at high speeds
Tire balance or tire belt separation (bad tire) would be my guess. check your wheel balance
This is my question Turns out it was a badly worn right axle Vibrating while braking is a warped rotor.
u might have your hose unplugged or a bad hose going to your throttle body that for sure will do that
check egr valve
A high pitch note vibrates more rapidly than a low pitch note.
Games at High Speeds was created in 2003.
A high-pitched sound results when a string or a column of air vibrates rapidly.
No you will actually save gas. It works pretty good actually.
When a car jerks or vibrates that usually means that the air preassure in AT LAEST one of the tires is to low. Fill up air in your tires.If that still does not solve the porblem and your car jerks and drifs then you should get your wheels alligned. They are not perpendicular to the road (or flat). That also speeds up tire ware. If your car vibrates at high speeds you should get your wheels balanced. Your wheel gets rotated in a machine, and then tiny weights are added to the wheel to eliminate any heavy spots on the wheel.
Because your motor is spinning faster at higher speeds causing higher rpm's
On the Ford 4.0 liter OHV , V6 engine the PCM starts cutting the fuel back at 5200 RPM in order to protect the engine when it is IN GEAR I believe it does it at 3000 RPM when there is no load on the engine ( park / neutral ) ( if that is what you mean by high speeds )
