Most Likely Causes
- 1
Internal belt separation
The tire's internal structure can separate from age, impact, heat, or manufacturing defect.
- 2
Impact damage
Potholes or curbs can damage belts even if the outside looks mostly normal.
- 3
Driving on low pressure
Underinflation overheats and weakens tire structure.

How to Diagnose It
- 1
Inspect for bulges or wavy tread
Look across the tread and sidewall for humps, bubbles, or uneven shape.
Tool: Flashlight
- 2
Rotate tire position only for diagnosis
If the vibration moves with the tire, the tire/wheel is suspect.
Tool: Jack stands, torque wrench
- 3
Have tire shop inspect internally if needed
Some separations are clearer once the tire is removed.
Tool: Tire shop equipment
How to Fix It
Replace separated tire
Do not repair a separated tire; replace it.
Inspect matching tire on same axle
Replace in pairs if tread depth or age difference creates handling or AWD concerns.
Correct pressure and alignment causes
Fix low pressure, alignment, or suspension wear that damaged the tire.

Other Suspension Issues
Browse more diagnostic guides in this category.
Alignment Out of Spec
Wheel alignment out of spec means camber, caster, or toe angles are wrong, causing pulling, uneven tire wear, off-center steering, or unstable handling.
Bad Ball Joint
Bad Ball Joint can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.
Bad Ball Joint Symptoms
Bad ball joint symptoms include a clunking noise from the front suspension over bumps, loose or wandering steering, and one-sided edge tire wear. Ball joints are critical safety components — a completely failed ball joint can fold the wheel under the car at highway speed without warning.
Bad CV Axle Joint
Bad CV Axle Joint can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.
Bad Tie Rod End
Bad Tie Rod End can cause clunks, pulling, bouncing, vibration, or unstable handling. Confirm the failed joint, bushing, shock, tire, or alignment problem before replacing suspension parts.
Bad Tie Rod Symptoms
Bad tie rod symptoms include a shaky steering wheel, car pulling to one side, uneven tire wear, and a clunking or knocking sound when turning or hitting bumps. Tie rods connect the steering rack to the front wheels — worn ends allow the wheel to move independently of the steering input.
Mistakes to Avoid
- Do not drive highway speeds on a tire with a bulge or tread separation.
- Do not patch a structural tire separation.
- Do not ignore thumping that changes with vehicle speed.
