I get that the cars are heavy, but the tires should wear evenly - 80,000lb tractor trailers don’t burn through the inside edge of tires at 25% of their usable life… As far as suspension is concerned, they did replace parts in the rear to allow them to better adjust the alignment, and I’ve put fewer miles on the vehicle this year, plus had a warranty repair that required re-aligning all tires again… But I’m going to be super pissed if it happens a second time.
