Thanks for confirming that this is abnormally high - I'm also running with the aero wheels with the covers off but I decided to go wider with 245/45R18s. I was getting about 280-285 wh/mi (cruising at 80mph) with the CC2s so when I switched to the PS4 AS, I was really disappointed by the really high consumption that I was seeing...This seems crazy high to me?
I've also got a 2018 LR AWD (with boost) and am running the PS4 AS, and getting like 280-285 wh/mi average.... was ~265 average on the OEM MXM4s on stock 18s without the aero covers on.
My driving is typically like 80-90% highway at speeds in the 70-80 mph range, then local roads in the 35-55 range for the rest.
Right before getting the new tires, I also upgraded the shocks with the Unplugged Autocross Adjustable Dampers and replaced the worn out FUCAs with new OEM ones and did a quick brake job to check the pad wear and clean out any accumulated dust in the calipers. I verified that the brakes aren't dragging too since ScanMyTesla reports accurate brake temps that match ambient while cruising on the highway.
I even went back to the alignment shop and had them check it and add 0.25 degrees of toe in which seemed to make a small improvement to efficiency, but the shop is clueless when it comes to EVs.
The only other mods on the car are the Ingenext Ghost module (I've been driving as chill so I can to remove this as a variable), upgraded front and rear sway bars set to the middle firmness setting, and I replaced the stock fabric aero covers with aluminum ones to protect the front of the battery pack.
I've had these mods on the car for a while before switching tires, so I'm suspecting that it could possibly be an issue with the rake angle of the car causing additional lift and dropping the efficiency, but I measured the ride height on all four corners to be within 1/4" of each other.
Anyone have any other ideas on what I can try before taking the car to Tesla and paying their insanely high diagnostic fee?
