Does uneven tire tread on a 4matic damage the car?
Last week I went to discount tire and the guy there told me that having uneven tire tread on an AWD messes up the differential, transmission and some other stuff, the current tread on the old tires is at 40%, while the new tire is at 80%+. He said I should get the other tires replaced ASAP.
I was wondering if he was right, n what happens if you have uneven tread on an AWD car, and if there was a possible reason to why the Mercedes certified shop didn't replace all 4 tires?
Thank you for your help.

Also on a side note, since picking up my car from the shop, at high speeds 70-80mph on the freeway my car doesn't feel right, sometimes the rear of the car feels likes its slipping or swaying slightly and I was wondering if this could be caused by the uneven tread or if its all in my head?
