Poor ev milage on 24 prime

I'm now seeing 44-46 on the projected EV mileage on a 2024 Prime, varying by air conditioning use and weather - here in South Florida we have the advantage of very warm weather which improves battery efficiency.

What I'm less clear on is the effect of tire pressure. The 32 psi recommendation seems low to me...I ran my 2017 Prime Advanced at 38...

 

You can do your own testing.
Try a tank full (or a few 'EV range' tests) with the tires at their 'Max Pressure' as stated on the tire sidewall.
You won't hurt anything. You might notice a harsher ride over small bumps.

 

The recommendation likely favors ride comfort. I find under 40 psi squishy in most cases. Higher pressure gives a stiffer ride, while reducing rolling resistance and tread wear. Take care when testing out higher pressures though. The traction might drop.

Also measure tread depth across the tire. Too high, and center will wear faster. Measure even if you don't change the pressure. Some gen2s at recommended pressure wore the sides faster, which means the pressure is too low.

 

I find the EV range is strongly affected by outside temperature. All summer I was getting 60-61 kms EV range, but as it got colder, now I get 50.
