Well, I doubt that will change anything, since there are no supported 19-inch options available for the X. The only settings available are 20 and 22. That being said, the range quoted in the display really has nothing to do with how far you can drive. Rather it is simply a tank fullness indicator based upon the "rated" range of the vehicle, which isIf I switch to 19" wheels from the 20" factory wheels on '22 Model X LR, what would the change in range be? Right now I get ~347 miles displayed when charged to 100%
There are a lot of factors, not just wheel size. The wheel weight, the wheel aerodynamics and also the tire rolling resistance. You could change your range by just getting a tire with lower rolling resistance which would be the most cost effective way to increase range.If I switch to 19" wheels from the 20" factory wheels on '22 Model X LR, what would the change in range be?

I thought the X could tow 5000 lbs.X is the only vehicle in the lineup that has to be able to whoa up close to 12000lb, and also the only one that hasn't gotten aerocovers, and I don't think that's a coincidence
Quite a reply. I was mistaken in that you referred to total tow vehicle + trailer weight is 12000 lbs. (X around 6500 and trailer is 5000), while I though you meant a trailer weight of 12000.Never thought of brake cooling on the X when fully loaded and tow. I use 19 " Aero covered MS rims on my winters but don't toe then so not worried about cooling. But can see the concern.You're aware Model X also has mass, yes?
Sure the trailer brakes, if you have them, do *some* work (mostly to keep the trailer from passing the tow vehicle in a panic stop), and the regen on an EV does 75-100kw ish, but the rest of the k = 1/2mv^2 you need to get rid of goes straight into the tow vehicle's brakes. Let's be generous and say regen and the trailer brakes do *half* of the work. In the case of a 65 mph panic stop towing fully loaded at around 11,500 including passengers and such, that's approximately one metric assload (about 1 megajoule) of heat you still need to get out of the tow vehicle's brakes somehow after one highway panic stop, with limited airflow because you're now going slow, what with having stopped and all, so your heat leaves the brakes through radiation and that means you need speed holes to make the car go slower
Now go down a steep descent on I70 for 15 minutes and tap the brakes every half mile or so, because regen doesn't quite keep the trailer and vehicle speed in check, you need to shed that heat in case you're panic-stopping next time you hit the brakes. That's what I mean.
I think they've left a little margin for brake cooling during towing on Model X that they didn't think they needed to leave on Model S or Model Y, for instance. It'd be nice if they released any information on their design decisions the way legacy OEMs do, but it's always so opaque. Sure would be nice to still be able to order the Cyclones.
