Have that tire checked sometimes the belts inside can break and cause a thumping noise
A thumping noise from rear tires can be caused by several factors, including uneven tire wear, a damaged tire, or improper tire inflation. It may also indicate an issue with the wheel bearings or suspension components, such as worn-out shocks or struts. Additionally, debris lodged in the tire or a bent rim can contribute to the noise. It's important to inspect the tires and related components to identify and resolve the issue promptly.
