2.2 on the Pirelli OEM AT in AP? Man, if that was what I got, I would have gone back to those... I think you're thinking on the highway tires... Or I may just have had a bad batch of tires...
Those calcs net about the right numbers... or close enough
Wow - those are great numbers for the OEM ATs - I don't know how to explain it other than I need to offload the truck from all the stuff in the bed, fronk, and tunnel lol
Iām at 2.24 for 12,000 miles 100% AP mode. I live in NH and have had the vehicle 1 year (so majority cold driving). Mostly short distance drives but I floor it all the time and do 75-80 on the highway.
OEM AT 20s. The noise is now unbearable so I need to switch tires.
These seem promising. That is a wild gain in efficiency claim. But iād be happy with equal efficiency as OEM so I might try them out.
Tire Rack says 34.1" for the Rivian spec
I am at sea level 85F with OEM tires and I will get 2 in the highway at about 72mph, your numbers would be more optimistic than what I get but not by a lot
AC is always running in Florida. Itās illegal to turn it off
Probably a very silly question, but how much does using Driver+ affect range? I can't imagine it draws that much energy.
Yeah, AFAIK almost everyone is getting 2.2 on the 20" OEM in AP. My lifetime is 2.2 over 20k miles, some conserve (and some RTT, etc.), but 2.25 over the past 7k miles with no conserve at all. That's why I have trouble with your numbers - you say 1.85 with the OEM, and a 25% improvement with the Nitto. If your driving style/conditions/etc. are such that your efficiency is that bad with the OEMs, I don't know how much I can trust your numbers with the Nitto.
I would guess very little. The cameras are watching regardless of you driving or Driver+ doing the driving. Only difference is who is providing the steering and throttle inputs. If anything, Driver+ might be marginally more efficient since it can hold a speed more consistently than the human foot (which is tied to an organic brain that is always looking to get a dopamine fix).
Highway Assist doesn't hold speed any more consistently than Adaptive Cruise Control. But Highway Assist DOES seem to adjust the steering frequently and far more often than I prefer - I refer to this as "micro-steering" whereas when steering on my own I tend to hold the wheel in one position for a long time unless I'm drifting. So I think HA might be slightly *less* efficient because it adjusts the wheel more often, but it would be by such a small amount that I don't think it would be measurable in normal driving.
