Effect of wider tires on range

[gearchruncher]

Consider for a moment the COST of that electricity to run the AC that 6kw over 100 miles or so . . . its $1 at Tesla's 50kwh supercharger, and at my home at 9.6 cents per kwh its 58 cents . . . not gonna stress it.

Wrong thread?
There are no 50kW superchargers, and I'm also pretty sure there are no 16 cent per kWh superchargers in the USA.

I do not have this issue :O
I have a M3 LR though, which has the LR brake rotors which means I'm pushed outwards 3-5mm compared to M3P I believe.

Yes that can make a big difference if the rubbing is on that central control arm spindle which has really tight clearance as you widen wheels and tires.

up to what KwH? I'm AVERAGING the production of the SuC and cost of electricity. . . for crying out loud - it us a MATH answer not a detailed accurate SuC answer.

Take your power [lets say 10kwh] and multiply times your COST of power [whatever the charge is] and thats what it costs - if you scroll up to pages 2 and3 you will see what I am responding to . . . .

I am surprised no one has done any experiments to prove/disprove this either way. Shouldn't be that hard...jack up car, coat bottom of whatever tire at x pressure with some dirt/dye/whatever, and then lower down onto a piece of paper...change pressure/tire and repeat.

This video did as you suggested:

I have that exact setup- 19" 265 PS4S's on a 9.5" rim, +35mm offset.
With the cruise set at 65, flat ground, 70F outside, I burn about 295 wh/mi. That's about 10-15% more than rated.


Physics just doesn't allow this.
100wh/mi at 75 MPH means you used 7500wh more in one hour, which means it draws 7.5kW.
The heat pump in a Model 3 isn't anywhere near 7.5kW. Even the old resistive heater was way smaller than that. Most home AC units aren't 7.5kW.

Agreed. In addition, wh/mi usage by consumer can be tracked in the energy app in real time.
