I have a 2021 model 3 awd and in Jan 23 I had to replace one rear tire cause of a road hazard, I paid $400 for a new one , which the one placed on the vehicle measured at 7 tread depth, since I had my vehicle the tread depth read 9 for all tires at 1166 miles, this was documented dec 11, they all read 6 in the front and both 7 in the back, I have a slight pull now . A friend suggested they shaved ? My tires to match the used one placed on it , ive read about this being done to new tire to avoid having to replace all of them , Michelin suggested it is my suspension but would the wear not have been some concern to mention in the work order?
