Note you can roughly scale the range numbers (there's a lot of rounding error so it doesn't work exactly) by the MPGe assuming the available energy is the same.

So for example:

299*116/113 = 307 rated miles (close to 304)
299*124/113 = 328 rated miles (not close to 322)
299*121/113 = 320 rated miles (close to 322)

So probably the Performance 18" would get a 326-328 mile rating but has been voluntarily downgraded.

I guess if there are ever official documents posted all will become clear...

People will whinge about 1% battery capacity loss but happily give up 5% for poseur wheels.

It's the coefficient of friction. Also why they stop faster and can take corners faster.

 

[ZoomsansVroom]

Increased rotation mass/unsprung weight is always the enemy. And, pretty much, the primary one.

If you want thinner sidewalls, order thinner tires, but the wheels should always be the smallest ones that will fit over the brakes.

I lose way more than that. I blame my foot.

I believe it. Well worth the loss for the looks in my opinion.

19" Look just as good. It's all about the tire compound any way. You can put sticky tires on 18" and get just as big a hit on range.

You actually get the widest choice of tires on 19" than you do on 18" or 20".

Actually tire compound is the primary one.

To clarify, I don't care at all about the lower "rated" range.

I just thought it was interesting in that I hadn't previously seen documentation of it...

More importantly, why is 2020 P3D+ less efficient than 2019 P3D+? Does that mean 2020 P3D+ has more ponies?

See above for the explanation. The 2019 P3D+ used the 2018 AWD with 18" Aero wheels test results, it appears, which is allowed if the take rate of the option is low enough. It's not 100% clear that's what happened in 2019 and why they were allowed to do it in 2019, but that's definitely what happened in 2018.

The 2020 P3D 18" is the most efficient AWD vehicle in Tesla's lineup. It is more efficient than the 2020 AWD. And the AWD is more efficient than it was in 2019 and 2020.

If you put 20" wheels on the 2020 P3D and make it a P3D+, it will get less efficient. But it's likely better than it was in 2018/2019 for the same vehicle.

Only on dry pavement though. No real difference in the wet, and if there is a bit of ice or snow...

Are the 2018, 2019, 2020 Model 3 Performance cars mechanically the same or were incremental changes made (other than HW3) ??

I sure wish Elon would have offered a 18" sport wheel option. I'd much rather have the smaller wheel, larger profile tire. A little smoother ride and cheaper to replace.

I'm dropping from 20" to 18" for fear of pothole damage on a road trip where there is no mobile service - it happened to me before....

We're gonna need to know the width, length, and weight of your foot to really understand the impact.

This is overall funny to me. The impact to range from the tires pales in comparison to the impact to range of the perpetual joy of even slightly pressing the accelerator and feeling yourself pushed back into the seat.

 

[Sutton 3P]

No, they are much grippier in the wet as well as dry. Since we are talking about summer tires, obviously they are not good in snow and ice.

 

[Adam3]

Its not strictly the wheels. The performance wheels have the super sticky Michelin PS tires. You would see a drop in range if you put these same tires on 18" wheels. Personally I'm OK with the range drop because I love the PS tires.

 

[BayAreaCelt]

The Performance we dont have the choice of all the wheels like you guys with the tiny brakes do...
