As I refresh my account tab 327 times a day awaiting any updates at all on my Model S, I happen to go by the regular "design your own" section of the website mostly to just see how far out new orders are. When I went there tonight, the est range for both the LR and Plaid was significantly less than when I ordered months ago. I took a screen shot of my order at my LR was 412 mi (est.) and now they are down to 375 and 350 (est) respectively. Being a first time Tesla owner, just curious if anyone else finds this odd?

MS LR Blk/Blk 19”
As of 9:08pm 3/14/21 the LR still shows 412?

The LR is 375 with the 21” wheels. Switch back to the 19s and it’s 412. The Plaid is 350 with the 21s.
The site was recently updated so now the mileage adjusts with wheel size.
Just switch back to the 19s on the site.

Yes the 40 mile penalty for great looking 21s is a tough pill to swallow. There are many reasons for the penalty but the biggest factor is weight. There might be some inefficiency with the stiffer sidewalls on the 21s. It's all about weight and rotational mass and with larger diameter wheels, the rotational mass hurts efficiency.

Been there done that with the 21's 2 out of the last 3 times. After having 19" in my Raven refresh I definitely went for the 19's again on our '21 refresh Model S. The 21's do look great but that is definitely where it ends. Our Raven S is a performance + Ludicrous and as far as drivability and handling and performance...there is no marked difference unless you were to MAYBE take it on a track. Otherwise curb appeal is about it. (after 3 Model S and ~275k miles of driving them I won't be going back to 21s again)
Yeah I am very concerned about having the 21" wheels, especially here in Omaha, NE - we have a ton of bad pot holes to go along with the suspect weather. I thought about going for the basic 19" ones and then buying some after market 20" wheels, but being a first Tesla, I really don't know enough about configurations / warranty issues/ OHM / TSportline issues etc on the new refreshes... heck, Tesla doesn't even know about the new ones, let along a third party aftermarket company. I really wish the 19" ones looked a little more appealing - I just don't like the style of these new 19 ones at all.
End of the day I think I'll roll the dice with the 21" from Tesla for the small discount at time of order and then order the 19" slipstream winter package tires when they come back available for the winter months.
Lol the Arachnids are expensive forged 21s. I wish the Arachnids allowed for a 265-40-21 and ‘40’ rear instead of 265-35-21. A 40 instead of 35 would help a lot.
Maybe the T Sportline forged 20s is a good compromise.

The '21 have:
1. a softer tire for better grip, which increases rolling resistance
2. are heavier, everything else being equal with a 21 vs 19
3. are staggered with much wider tires with more contact area, wind resistance in the tire and even more mass
4. rims designed for brake cooling, vs the 19 which are mostly aero

Wow that’s great, I expected 255-45 all around. On the site, you can see the 19” front tire is 255-45-19 but you can’t see the size of the rear 19 and 21 tires.

On the prefresh S, the 21" arachnids weighed less than the 19" aero wheel. The arachnids are expensive because they are full forged unlike Tsport's partially forged wheels. The tire weigh about same.
The efficiency penalty is due to airflow over the lower sidewall of the 21 vs the almost flat profile of the 19 aero tires/wheels. Also the compound and width of tread seems to make a large difference in the rolling resistance. The summer high perf tires are much stickier and 21's are wider.

Absolutely.. I purchased a Macan Turbo a few years ago and it came with 19” wheels. I swapped out the 19s for (heavier but nicer) 21s which were definitely less efficient (gas mileage.) I also noticed an acceleration penalty.
