The new 21" Aero Design wheels

[d00d]

I started out liking these, and found them on ebay in both all black and diamond cut, but couldn't unsee the cutout for the valve stem.
Ordered these 20" instead, along with -1 sized Hankook ION EVO AS SUV 235/50R20 XL and 275/45R20 XL.
I'm predicting 10% better mileage over the 21" Mission E , we'll see.

Update: all season 235 fits but the 275 too narrow, and there's no 285, so went with Continental ProContact RX all seasons in standard sizes

Not been able to find these wheels and tyres on the Porsche site so far.

I wonder if the dimensions also would reqyire an update to the PCM since I guess the circumference may be slightly different. Such difference might trigger problems with ABS etc???

I can see that the Hankook tyres are available to order in these sizes and NFO certified. The price is also very attractive and EU test sound level a few decibel lower!

Did you notice a big difference in range? What was the reason you swapped the mission e wheels for those?

Not a huge difference, but enough to make it home subzero with less stress, swapped for mileage.

it actually says " Not recommended for use on the circuit. " Has anyone compared its track performance? I tried pulling 1.2G of steering from it but havent tried more.

Edit: that was at about 50mph on a track during a curve, dont know if it matters too much if speeds differ.

Inteeresting to listen to Kyle Connor of OutOfSpec video report that at the 2025 Taycan reveal in Germany he talked with the Taycan Engineers, one of which said to him that these 21” Aero Design wheels are almost as range efficient as the 19” standard Taycan wheels. On the French configurator site, for a 2026 Taycan 4S Cross Turismo, the 21” Aero Design wheels result in a WLTP km range of 608 whereas the 19” standard or the optional 19” ones have a km of 614.

How true the above posts are that stated that the narrower Aero Design wheels compared to all other wider 21” ones would not be the correct ones for all who are tracking their Taycan!

I must disagree with all that! Whilst recognising it is personal choice and taste but I fail to see how a jumped up SUV can be anything like as much fun as a Taycan. Worse handling etc etc - oh and I love my 21 in Taycan Cross wheels!

Agree with Argree! I recently bought my wife the Macan EV with 295 "fatties" on the rear wheels, and while the car is just about the only SUV that is both fun to drive -- and not embarrassing to be seen driving (I'm totally anti-ICE for purely environmental, not political, reasons), the handling/fun factor compared to the Taycan with low profile 21 inch wheels just isn't the same.
