1) Chunky all-terrain tread (the main culprit)
Those big blocks on the 20" Pirelli Scorpion AT:
Bend, twist, and “squirm” every rotation
Trap and release air
Generate heat (lost energy)
👉 This is the largest contributor to rolling resistance in your comparison.
It’s why EV range drops so...
Taller sidewalls (20-inch wheel setup)
→ More flex, more deformation
→ More energy loss
→ Higher rolling resistance (generally)
Shorter sidewalls (22-inch wheel setup)
→ Less flex
→ Less energy loss
→ Lower rolling resistance (in isolation)
It's mostly the rolling resistance of the taller sidewall the flex of the sidewall creates higher resistance and thus needs more energy to over come that resistance.
I seem to be going the other direction to everyone else.
I had an OG R1T 2022 w/20".
I now have a 2025 R1T G2 w/22".
Pros 22":
1. Better range = Less charging cost and less charge time (way better to me #1 reason)
2. Quite
3. Better dry road traction
3. For me the sport look
Pros 20":

I think cameras plus LiDAR is the best option, and I would like L4. Don't get me wrong I love both companies (Tesla + Rivian) own 1 of each.
Rivian is making leaps forward catching up to Tesla in the assisted driving realm.
Do you think the LiDAR would help the Tesla vision? I do, it still...
I am a OG waited 3 yrs and 21 days to get my pre order from 2019. Ordered a R1T glacier white, quad motor (only one you could order) 835HP with the off road package. Two moths ago I traded it for a 2025 R1T tri motor 850 HP with sport 22" street tires and dark out package.
I love the truck, the...
If Rivian lays off 140 assembly-line workers, the approximate annual cost savings can be estimated using the total compensation per worker.

🔢 Calculation Assumptions:
Total annual cost per worker (wages + benefits): ~$88,000 (from prior estimate)
Number of workers laid off: 140

Per Chat GTP this is my new brain!
Layoff savings.
For an assembly-line worker at Rivian, here's a breakdown of what the average compensation package looks like — including both pay and benefits (i.e., total cost to the employer):
