Different tread depth cause vibration
 

So i bought used tires from cl.
They looked good to me at the time so had them
Installed and got an alignment.

But the car vibrates

After some inspecting i found out the 2 fronts have uneven wear
Eyeballing it the right has 80%
the left around 60%

Any help would be appreciated

Were the tires balanced after being installed on the rims.

Inspect tires for side to side wobble, out of roundness, bumps, bulges, etc.

Start rotating in the spare tire at each wheel location to determine if this helps the vibration issue.

Tire wear alone should not cause issues if wear is even on tire (tire still round). If you purchased 4 tires pick 2 tires having the same amount of wear and put these on the front.
