Mini Review My Trip To Vegas With One Concern?

[MyFirstElectricTesla]

Last Father's Day 3 days weekend Sat - Mon.
~270 miles from Orange County SoCal, both from ~5PM to avoid traffic.
Full size OEM tire/wheel, Dewalt Air Compressor w/3 batteries, jack stand w/10 tons bottle jack, few pieces of 2x4 wood, 240 pieces tool box, lug wrench and luggage for 2 of us for 3 days.
Temp was a little hotter than this weekend, I've seen 114 outside temp from my CT.

Trip to Vegas:
- 99% charge to start.
- I've feathered the pedal between 62 - 65 MPH.
- Non stop w/No traffic.
- Arrived at Caesar Palace with 21% left.

Trip back home:
- 98% to start.
- FSD the whole time, Iv'e seen 77 MPH few times.
- Stopped to charge somewhere my CT chose to charge about 10 minutes to finish the trip.
- Only one time about 15 minutes construction traffic on 60 freeway near home.
- Around 11 % when home.

Here is my concern:
- All my tires at 54 PSI "cold" to start the trip.
- The next day after we came home they were down 50 PSI.
So I guess the high temp is the reason to loose PSI? I hope it's normal.

You’re over thinking it. Too many variables will give you different battery percentages. I make this trip every other week for years, with my Model Y and Cybertruck. And yes the PSI is due to temp.

With the most recent update, I usually set FSD to max 85 mph but also set to “standard” not hurry so it doesn’t camp out in the left lane.

If you flipped those start and finish locations the battery percentage would make more sense to me. Assuming same wind conditions in both directions.

just let the car decide and don’t over think.
