Driving slow to medium speed noticeable dull wobble sound coming from the tires. Tires holding air steering smooth and not effected.Tires have only 22000. Wife hit chuck hole hard. What is cause?

The dull wobble sound you’re experiencing could be due to a bent wheel or a damaged tire from hitting the chuck hole, even if the tire appears to be holding air. It's also possible that the tire has developed internal damage, such as a separated tread or belt, which may not be visible externally. Additionally, check for any misalignment or suspension issues that could have arisen from the impact. It’s advisable to have a professional inspect the tires and wheels to diagnose the issue accurately.
