To our surprise we recently had a rear tire blow out on us. Our car has around 45,000 km on it. After inspection the tire was heavily worn on the inside with very little wear towards the outside edge. Every tire was this way and were very close to blowing as well. I replaced the Scorpion tires with Nokians and Kal Tire told me the wheels are significantly out of alignment and it must have been from the factory. The 3 remaining tires were bald on the inside which explains why I was always sliding around in the snow. I purchased the Scorpion tires and rims from Tesla. They installed them 2 years ago and the car has been in service since then so it shocks me that they did not notice the uneven wear on the tires, or the misalignment.
I have the car in for service today at Tesla for an alignment and they are trying to tell me that this uneven wear is normal, especially if the suspension is set too low. They said it is a common complaint for Model X owners because the car is so heavy. I'm not believing this because my Ford Edge is nearly identical in weight and my Nokians have lasted 10 years and over 130,000km on that vehicle. I'm not convinced that I am going to have to replace my tires every 1-2 years on the X and feel there is either a design flaw leading to the alignment issue, or they set it incorrectly from the factory. Either way I'm fairly upset that I had to spend $1,600 CAD on a new set of tires after only 2 years and 45,000 km. This is not an ongoing cost that makes sense for this vehicle. I am wondering if anyone else has seen similar alignment and uneven wear on their tires. If so, have you had any luck with a warranty claim on the tires?
