Your main mark on Tesla is
Your main mark on Tesla is the price of a tire change, gathered from cherry picked data. On the very forum that you've posted (which is about a Model 3 a faster and more sporty car) about how long the tires last, the main consensus is that "it depends" on the tire, the roads, and the driver. Not to mention your source is a forum with no real facts or verifiable information, simply just subjective experience. But lets say they're correct. The main contributor to tire wear, however, is driving style and weight. Electric cars (both BEVs and PHEVs) have high and instant torque, that can be a major contributor to tire wear, will we see that same thing happening in Toyota's second quickest car? I think so.
Both the Tesla Model Y (4416lbs) and the Rav4 Prime (4300lbs) are very heavy cars with the Rav4 Hybrid (3800lbs) weighing 500 lbs less than the Rav4 Prime. With vehicle weight and torque considered you can't use the the Rav4 or the Rav4 Hybrid as a fair comparison; apples and oranges.
For the price of the tires (255/45R19) on TireRack however, the least expensive OEM sized tire are the Laufeen S FIT AS at $121.48 with a set of 4 at $485.92.
Your math isn't wrong, your use of cherry picked data is. The Toyota Rav4 Prime is an amazing vehicle and I think that Toyota has really out done themselves with it but so is the Tesla Model Y.
P.S. "Although we suspect that brake services at Tesla may be more expensive than at Toyota" Regardless of inclusion in the story; you are clearly on a thorough fact finding mission to get fair information that doesn't serve to tell a predetermined narrative.
