I bought my 2021 Mazada3 Turbo used at 18k miles. From day 1 i had it, it shook like it needed a balance. 3 balances later, the dealership finally finds a front right bent rim and bent wheel hub. They replaced both. The car seems like the shaking is better but its not gone, especially between 50-75. I took it back to the dealer again and did a test drive with the foreman. He told me that the shaking I am feeling is from the front tires "feathering" because the mazada3 has "so much negative camber". He had me feel the tires with him and i honestly cant tell a difference between the good tread and "feathing" tread. They also look perfectly fine to me. Has anyone heard of this type of issue coming from extemely minimal feathering? Or any other ideas?
The shaking is throughout the entire car but is very noticable in the seats and any cups in the cupholders practically do a little dance while driving.

 

An update just in case someone on google comes across the same issue.

I went to the sister dealership of the original dealership and had a technician do another inspections. Tires are perfect. Tech recommended a road force balance, cleared the issue right up.
