I'm at my wits end with my Model X tires! I've replaced the rears twice in two years and now the inner linings are shot. First it was Michelin tires from Costco, then I replaced all four, but the problem persists. Tesla says everything's fine, but the tires keep wearing out prematurely. I'm spending a fortune on new tires and alignments. What could be causing this rapid tire wear? Is it the car, the tires, or something else?
