Scorpion AS+ tire swap (from 20" Scorpion AT) - WOW big difference

[Supratachophobia]

Are you talking 20" aero inserts? If so, that's a touchy subject... but I'm happy to sell mine to you!

I didn't know the 20's had aero inserts as well. I do remember that on Tesla's, rim aero improvements can net you up to 2% better range.

Here's my ride home from Bellevue, 72mph on the highway when I could with All Purpose /stiff/ standard. My arrival miles fluctuated throughout the drive (chalking that up to rain) but I got home with the same starting number. Also a 16% improvement on the 20" ATs I drove there with the loaner!

Sorry, is this good?

It’s VERY good.

This is really good. I get about 2.1 with ATs at 70mph - in Conserve!

If you're getting 2.4+ not even in Conserve, and +2mph faster, that's a fantastic result. Around 15% better and would probably be a couple % more in Conserve.

We've got rain the next couple days, but Thursday/Friday I'll do some tests and report back. If Thursday results like my normal commute tests, I'll try Conserve Friday.

So this is on 20' tires and you are getting consumption similar to the stock 21's?

20" wheels with tires changed to the subject AS+3 in 275/60R20, yes.

As I've said in other places, there are so many factors in these vehicles efficiency/consumption it's hard to credit one distinct characteristic to improved efficiency. You have to compare apples to apples, exact same vehicle in same conditions. Perhaps I'd get even better efficiency with stock 21s, I just have no interest in getting anywhere near those things.

This is from my Sunday drive across Colorado, looking at Fall colors, over multiple mountain passes, a good amount of 75 mph on highway, but much slower on some dirt roads. I’m happy with the efficiency of the stock 20s, but will consider the Michelin Defenders when these wear out.

This is with stock 20s???

Yes. I did almost the same drive a month ago over Labor Day weekend and got 2.73 miles / kWh

Yes. I did almost the same drive a month ago over Labor Day weekend and got 2.73 miles / kWh, as there was more traffic, less able to do 75 mph, which makes a big difference.

On conserve, right?

On Conserve when on highway, which may be 75% of the miles (?)

 

[shap]

Make sense. Great result regardless

These are ridiculously good numbers. On stock 20s I get 2.1 - 2.2 on Conserve going 70, cruise control. With the aftermarket aeros.

I just took the aeros off so I'll see if it improves at all when I get my truck back from service center in hopefully a couple weeks.
