Ah got it. Yes, that’s exactly right. Wider tire, different tire, more offset and no aero wheel all add up in a big way. On some brief highway runs I think the efficiency loss is easily 15%. It’s pretty serious. Looking good comes with a little pain!
You could always try driving slower, pretty sure all of this compounds with speed.
On my setup driving from Irvine to Santa Monica in 50min takes 35% battery and in 1hr 20min takes 25% battery, both cases I have AC ON at speed 5, so despite running AC for +30min its still a lot less energy demanding to just slow down.
Also, that drive is 53 miles which means my car's true range is at best case 212 miles
I'm on stock Model 3 LR AWD 19" sport wheels with OEM 235 tires
I have done the Irvine to Santa Monica drive (and back) many times, its almost always 25%, sometimes its 23% some times its 26%, 35% was only achievable when all stars aligned and road was dead empty
Tires are at 43PSI, I suppose if I raised it I could improve my range but the road is already bumpy as is
There's probably a FastWheels EV01(+) in my future (esp now that they come in all black too)
Oh and there's definitely a tipping point; slow is good but if its stop-go its terrible, I had the misfortune of making that route during 4th of July weekend, took 2.5hrs for the same 53 miles, it was about 39% battery :|
