I thought the stock staggered wheels are 8.5" and 9" width.

Yeah, I don't know much about these new fangled electricity cars, but I think Den is correct.

Btw, pretty ride, pretty wheels (not sure I have the patience to clean 18 spokes though), and cool mucho rubber! WOW!

The last "ultra light" wheels I had would have been better labeled as "super soft". On a car as heavy as the Model S, I'd worry more.

If you can get a measurement on improved (or not) performance and efficiency, that would be interesting however.

Those wheels look fantastic! I was actually thinking about going the same route. The Model S in red with nice aftermarket wheels is one of the sharpest vehicles on the road.

Those are fully forged wheels. The OEM wheels are cheap cast, much weaker.

The forged wheels I purchased from Vossen for my Model S weigh ~25 lbs each. That's about a total of 40 lbs in savings. An interesting fact when doing the math: saving 40 lbs of rotational mass will net a 0-60 gain of around .15 to .2 seconds and a range increase of around 10 miles!

exactly, forged are stronger, lighter.... I ran a set of these on my P85D for a year, no issues.....

Great wheels, but I can't understand going with 21" with all we know about flats on sharp potholes. $300 a pop.

20" at best, and these don't come. (Not to mention they're a ridiculous $2,500 each)

70k miles across 3 Model S with 21s", never had an issue....

Carbon fiber wheels are interesting, but the design is pretty plain/basic. Hard to spend $10K on wheels you don't absolutely love.

They should pretty much be flat discs. Better weight and aero with less labor, probably 15lbs a piece. I assume most people wouldn't like the look, but the spokes/ventilation is a waste on a Tesla.

They are already ~12 pounds each with the current design. Also they make custom wheels - I wouldn't assume this is their only design. Cost is $8K for four. The ESE Carbon Company produces ultra-light weight carbon fiber wheels for the automotive aftermarket, which weigh in at less than 11.5 lbs (5.2 kg) and are rated for a maximum axle load of 3,850 lbs (1,746 kgs).​

Eric Escribano, President and CEO, ESE Industries, said the collaboration between DSM and ESE has resulted in a great product breakthrough. The resulting ultra-light weight carbon wheels can be custom-made and designed according to specific OEM preferences, as well as tailored for a full range of applications across multiple industries, he added.

Just imagine in a couple more years they will be 3D printing these things...

Nah, CF must be fused at high temperature and pressure, to activate and flow the resins.

That said, I can't believe it's strong enough for a wheel. Are there steel sleeves at the lugs?

I'm pretty sure they use titanium for the lugs or steel, the other manufacture that I checked out was Carbon Revolution, and thats what they use. They are definitely strong enough - 3800 lbs per wheel exceeds most specs you see on aluminum and forged. Most of aluminum and forged are only 2200 lbs per wheel. I plan to buy these, but might make a trip down to see some finished products first.

I've been using carbon rims on my road bike for years with no issues. Also motorcycles have been using them for years - this is just the next natural progression for the technology as the costs get lower.

Here is the 3D Carbon Fiber printer I mentioned above
