As an automotive expert with years of experience in the field, I've seen a variety of issues that can cause a tire to wobble. A wobble in a tire is typically a sign of an underlying problem that needs to be addressed to ensure the safety and performance of the vehicle. Here are some of the primary causes of tire wobble:


1. Wheel Out of True: If a wheel is not perfectly round, it will wobble as it rotates. This can be due to manufacturing defects, damage from hitting a pothole, or wear over time.


2. Bent Wheel: A bent wheel is a common cause of wobbling. This can occur from impacts, such as when a vehicle drives over a curb or hits a large obstacle.


3. Tire Out of Balance: When a tire is not properly balanced, it can cause a wobble at certain speeds. This is often noticeable at higher speeds, as you've mentioned.


4. Wheel Bearing Issues: Faulty wheel bearings can cause a wobble or vibration that may be felt in the steering wheel or throughout the vehicle.


5. Suspension Problems: Issues with the vehicle's suspension system, such as worn bushings or struts, can lead to a wobble, especially if the problem is severe.


6. Tire Pressure: Incorrect tire pressure can cause a tire to wobble. Both overinflated and underinflated tires can lead to uneven contact with the road, resulting in a wobble.

7.
Tire Damage: Damage to the tire, such as cuts, punctures, or bulges, can cause it to wobble as it rotates.

8.
Wheel Alignment: Poor wheel alignment can lead to uneven tire wear and may cause a wobble, particularly if the alignment is significantly off.

9.
Brake Issues: Sometimes, issues with the brake system, such as warped rotors or uneven brake pad wear, can cause a wobble.

10.
Drivetrain Problems: In some cases, problems with the vehicle's drivetrain, such as a worn universal joint or issues with the transmission, can manifest as a wobble.

It's important to diagnose the exact cause of the wobble to address it properly. A professional inspection and diagnosis are recommended to pinpoint the issue and ensure that the necessary repairs are made.

The most common cause of vehicle wobbles in this speed range is a bent wheel or mildly out of round tire. Transmission and drive line issues can also show up in this range, but tires are the first thing to check. ... The most common cause of vehicle shakes at 50 mph or higher is tire balance.read more >>
