Why are you running a 285 on a wheel that wide in the back?

Just seems stretched for me if you care about performance. Figured I'd ask.
If anything it would help performance and quick maneuvers. But makes it easier to curb rash, and it does give it that stretched look, but it doesn't seem a crazy stretch to me.

I ordered a 295 and went to my apt and was told they never got it. Threw a 285 on and thought it fit well. They do poke a little bit and a 295 would amplify that and make lowering difficult.

Always loved those wheels! I had a set on a 335i I had a few years ago.

You're a little small on your rear tire though. Should be a 35 instead of a 30 at that width. 285/30/20 is a whole inch shorter than a stock 275/40/19. Realistically you can run a 295/35 with that offset while lowered 1" in the rear. That extra 1/2" of sidewall will make a pretty big difference in ride quality.

My car came stock with 255/40/19 tires. So a 285/30/19 is not that far off from overall diameter. I would agree with everything else you said though. I was looking for 285/35 before I landed on 295/30/20 due to it being exactly the same overall diameter as the stock 255/40/19. Like I mentioned above I settled for the 285/30 because they had it, and I ended up liking it when I saw it. So yeah not optimal to the fullest sense but good for me! Car is also not the daily driver anymore so ride quality has rooom to compromise a bit. Just drove a good amount of miles the other day and they honestly felt fine.

Here’s the look on a set of stock TESLA Pirellis. They’re 275/30s (I bought these from a guy who had them on a Model 3) I got rid of these tires ASAP.

You’re right. I was thinking the PP rear tires. Those are 275/40/19. Didn’t know the other models were smaller.

Yessir, non PP car here. 255/40/19 squared stockies came with mine. So I mean yeah in terms of sidewall cushion maybe I’m lacking. In terms of speedo error though there is essentially none.

FWIW IIRC Tire Rack did tests with wider, narrower and manufacturer recommended width performance tires and slightly wider than recommended wheels performed best by very small margin.

Teslas do that intentionally, partially for the performance but mostly for aero.

Don't like how that increases odds of curb damage with tires that have little or no protection molded in for that. No such thing as filler and touch up paint for bare metal. Even if you have an SO to blame it on, still gets expensive to replace a wheel for the slightest kiss.
