* Wheel Balancing: This is the most common cause. Even with new tires and rims, they might not be perfectly balanced. An imbalance creates vibrations that become more noticeable at higher speeds. This is the *first* thing to check.
* Tire Balancing (Road Force Variation): Even if statically balanced (balanced while stationary), tires can have uneven road force. This means different parts of the tire contact the road with varying force, leading to vibrations. A road force balancing machine is needed to identify and correct this.
* Wheel Alignment: Incorrect alignment can cause the tires to wear unevenly and induce vibrations. Check the caster, camber, and toe angles.
* Tire Issues (despite being new): While unlikely with brand new tires, manufacturing defects can still occur. A tire with an internal defect could vibrate.
* Bent Rim(s): Even new rims can be damaged during shipping or installation. A bent rim will definitely cause vibrations.
* Hub-centricity: If the wheels aren't properly centered on the hubs (using hub-centric rings if necessary), it can create vibrations. Improper fitment can also lead to issues.
* Brake Rotors or Calipers: Warped brake rotors or sticking calipers can also contribute to shaking, especially noticeable during braking, but sometimes felt as a vibration even while driving normally.
* Driveshaft Issues (less likely): Problems with the driveshaft are less common and usually involve symptoms beyond just vibration at a specific speed range, but it's worth considering if other checks don't reveal the cause.
What to do:
1. Go back to where you got the wheels and tires installed: This is the easiest and most logical first step. They should diagnose and fix the issue under warranty if it's due to installation errors or faulty components.
2. Have a professional wheel and tire shop check the balance (road force balancing recommended): If the issue persists, thorough balancing is crucial.
3. Get a wheel alignment check: This should be done even if balancing resolves the issue to prevent future problems and uneven tire wear.
Larger rims and tires, particularly 22-inch, are more susceptible to vibrations because of their size and mass. Proper balancing is even more critical. Don't ignore the shaking, as it can cause premature tire wear and damage other components of your vehicle.
