i4 m40 rear wheel drive, OEM 19" Goodyear Eagle Sport. first rear tire failed around 18,000. massive inside edge wear down to the metal cords then a blow out and instantly flat. first thought is out of alignment, took it in, not bad, perfect new alignment, then 2k miles later the other rear tire blows in the same manner, stranded both time. NOT an alignment issue .
BMW dealer said I should be more careful and monitor the tire wear better. BMW North America said nothing they can do, dealer issue.
i4 m40 is 25% heavier than similar 4 series and yet they use the same tires. 900 lbs added weight, added torque, the added heat from the weight and torque.
this wear is super hard spot and seems to accelerate very quickly at the end. see pics from both tires.
not happy with BMW. I had this issue with all three of my i3s, but at least it was even wear and could be seen. I asked my dealer prior to ordering about rear tire wear, was told it was normal, nothing special and used standard tires, not special EV tires.
to me this is a BMW issue, either bad OEM tire choice, bad batch of tires from Goodyear or bad design (camber/toe in) set up.
