Model S 2021 refresh tire / wheel size

[Aggmeister2010]

Do we think it's safe to assume the fronts are 21x9.0 and the backs are 21x11? That's what I'm going for based on this chart of recommended tire sizes. Tire equivalence: Car tire tips - Pneus Online
All the previous S wheels were+40 offset, so curious if that's the case with the new ones.

You might be right. 295 is the 'ideal' tire width for a 11" wheel.

any info on 19” sizes?

Will the original arachnids work on the refresh LR?

I have ordered a refresh LR to replace my nearly 8 year old Model S P85. I received pretty much all the referral bonuses including the Elon-signed wall charger and the silver Arachnid Wheels. The latter are on my P85 at this point, I was planning to switch back to the original 19" wheels before selling my P85 but may rethink that if they won't be the right fitment for the new car. Was hoping to powder coat them black or gray (white car on order), they're in great shape except for one small area of curb rash which I'll get fixed.

For those that are interested, here's the Wheels and Tires page from the owner's manual...

Good find in the manual.

I like to split the difference and run 20" aftermarket rims for a nice balance of looks vs ride comfort. When plugging those numbers from the manual into this tire size calculator, I suspect any new designs from T-Sportline will be the following to keep things equal:

• Front: 9.5" x 20" rims (with perhaps a slightly more aggressive offset), wrapped in 255/40R20 rubber
• Rear: 10.5" x 20" rims (with perhaps a slightly more aggressive offset), wrapped in 285/35R20 rubber

Looks like the Perilli P Zero high performance all season tires are an option in both those sizes already. Nice. Now just waiting to see what T-Sportline comes out with for the refreshed model.

Right after our baseline measurment on the new Plaid, we went ahead and start the production of a set of 20" SV104 for an lucky onwer who is getting his plaid deliver in 2 weeks.

Setup inspired by the Plaid+ prototype. Aggressive 5 split spokes.

20x9.5 (265/40/20)
20x11 (295/35/20)

What's the estimated weight on those? The price seems high compared to something similar like the Vorsteiner V-FF 103.

Our 20x10.5 SV104 weight 21.1lb.

—————————

Signature wheels are all fully forged.

Vorestiner V-FF 103 are flow form ( cast face with rolled barrel)


Apple to apple comparison:

Signature SV104 ( retail: $1375 each) vs Vorestiner VNF 501 ( retail: $1895 each)

Gonna love the new look.

Goodbye to the heavy cast OEM and hello to the fully forged Signature

^ Do you have any way to measure the range impact of those?

20" is going to have better range over 21". Didn't have the data for the new Model S yet but you can expect around 3-5% on range improvement. (Based on our date for the previous Model S and Model 3)

I thought the penalty was in the aero, not in the wheel size? I.e. if 20" has worse aero than 21", then mileage will decrease even if wheel size decreases.

If its not the aero, what causes such a decrease?

Arachnid and SV801 like above both had open-spoke designs, and neither of them is design for best aero.

Smaller wheel = better aero. The easiest way to think of is that air has to travel about 4% longer distance on the 21" than the 20". That's why you would see better efficiency with a smaller wheel.

That's what I was leaning towards believing ... 285 front factory tire sounds pretty immense. Maybe he thought the 6 was an 8. Details & all that. ffs.
