Yea I was checking out the Induction wheels when I picked up my Y today. 255 on 9.5 has a bit of a stretch which Is the look I prefer. I think 9” would have been perfect. 8.5” just looks beefy for my taste. I’m wondering if I go with 245/40/20 on 8.5 will give me the same look as the Induction with 255/40/20 on 20x9.5.
245/40/20 will not work because there are no tires in that size that meet the 101 XL load rating of the 20" wheel equipped model Y. What I mean by that, is you're unlikely to find a tire shop to mount them. For what its worth, the 255/40 on 8.5" wide wheel like my car, actually does look good in person. To me, the stretched look of the inductions doesn't look right unless you had spacers and the car was lowered. With the stock ride height and wheel offset, the 8.5" wheel looks quite good.
Sidenote - and I may start a whole thread about this. Discount Tire (a company I actually love) would not even mount these new wheels on my car, because my model Y came with the gemini wheels. The 255/45/19 tires which come on the model Y are a 104 load rating, because well... thats how tires that size come... So when I came with my 20" 255/40/20 which are a 101 XL load rating - which perfectly matches tesla's spec if you get the car with induction wheels.... they wouldn't put them on the car. I've escalated this whole issue to corporate at discount tire who will eventually check with tesla and realize I"m right, but what an absurd run around. Right now, its as if discount tire treats the model y long range as two different models. Gemini version, and induction version
If you didn't understand any of that, just know that if you're getting 20" tires of any size, they need to have a 101 XL load rating minimum.
