I think the difference with the aero inserts is likely attributed to the 5.5% lower average speed instead overall, however you gained 7% efficiency in the high speed section...

Have you been able to find what the diffence is between the original and the defenders as efficientcy gains?Put me down as another happy Michelin Defender LTX owner. I took the Pirelli Scorpion All-Terrains off of my 20" wheels a couple of days ago, and instantly prefer the Defenders: smoother, quieter, quicker, better ride, better handling. Though to be fair, none of those a HUGE differences.
But I'm also hoping for (too early to tell) better efficiency, longer life, and lower cost.
I stuck to the OEM size of 275/65/20. I would have liked to size down, as I suspect (not positive) that would be cheaper, lighter, more efficient, and handle better. But the OEM size won't cause objections from tire shops, should cause fewer objections from Rivian, doesn't require reprogramming (or living with speedo/odo differences) and likely has a better ride and less chance of damage from potholes and such. If nothing else, a Defender in the OEM size is going to be better than the OEM Pirellis on the things I care about.
It's true that the Defenders don't look as good, and they certainly don't off-road as well - but I don't drive off-road.
With the new tires:
Is the tire pressure for for the Defenders 80psi? If so do they ride harder (harsher)?I can't say the difference because I didn't have the original ATs long and didn't run any tests with them.
But in post 105 I gave some efficiency results with the Defenders. 2.12mi/kWh at 75mph - that's a range of about 271 miles? (I did 7% better than that with some aero inserts in the wheels, though that's not the comparison you're asking about.)
On a much-longer run, but with average speeds of only 54mph, I got 2.34mi/kWh which is roughly 300 miles. (And again, 7% better with the aero inserts).
Thanks. I don’t often use conserve. That was my first significant trip with an EV; so I used conserve just to begin learning about my R1S and it’s capabilities. That trip showed me range anxiety is a non-issue for me.
What aero inserts are you talking about? Do you have a link?I can't say the difference because I didn't have the original ATs long and didn't run any tests with them.
