* Tire balance: This is the most common culprit. Improperly balanced tires will cause vibrations at various speeds, and it's especially noticeable with larger rims and lower-profile tires. Get your tires rebalanced.
* Tire wear: Uneven tire wear, such as cupping or feathering, will induce vibrations. Inspect your tires for unusual wear patterns. If the wear is uneven, it might indicate a suspension or alignment problem.
* Wheel alignment: A misaligned suspension or wheels will lead to vibrations and shaking, especially at higher speeds. Get your alignment checked by a professional.
* Bent rim or wheel: A bent rim, even a slight bend, can cause shaking. Inspect your rims carefully for any damage.
* Suspension problems: Worn-out suspension components, such as ball joints, tie rod ends, or control arm bushings, can lead to vibrations and shaking. Have a mechanic inspect your suspension.
* Driveshaft issues: Problems with the driveshaft, such as imbalance or worn U-joints, can also cause vibrations.
* Brake rotor warping: Warped brake rotors can cause pulsating vibrations, especially when braking, but can also contribute to a general shake.
In short: The large rims themselves aren't the direct cause of the shaking. The issue is likely related to something else, often something connected to the tires, wheels, or suspension system. A mechanic should diagnose the exact cause. Don't just assume it's the rims.
