40-42psi is a very good compromise between efficiency, wear, and ride. 38psi works fine if ride is the #1 consideration.

Not comfortable running any tire at max. Nor too low.

We run the stock Michelin Energy Savers at 40 psi cold.

We will upgrade to tires with a higher max pressure rating before going higher.

What tires are rated to higher max pressure?

Why are we locked into talking about tire pressure??

The issue is the range test video... My reaction is that the test was impressive, even though it was flawed.

I drive at 70mph when I forget to unplug my car and mistakenly charge to 100%. Then I drive up and down my local highway at 70mph to quickly drain down my battery to 75-80%.

While driving at 70mph, I use almost double the energy that I use at 55mph.

SO - I think this man's test could have easily reached over 220 miles of range.

I do like the 70 MPH trials, as that's a normal driving speed for cross country trips, so it is important to understand the range at that speed.

My comment about tires, is that if we are comparing against Tesla or the Bolt, the tire pressure should be consistent.

Running a tire pressure lower than 40 psi runs the risk of excessive wear on the outside edges of the tire and poor cornering due to excessive rolling of the tire. Nissan used 36 psi to soften the ride at the expense of tire wear. 40-42 psi seems to be the sweet spot.

I don't strongly disagree, but I ran my 2018 with 38psi for the first Summer, with no issues. At the first tire swap I raised it to 42, letting it drop to 40. I didn't do much hard cornering, though.

I was running worn out ecopias at 42 to 44 and didn't really notice losing any range going to energy savers at 38 psi.
The energy savers are wearing good at that pressure.

What tire pressure do you guys think provides the best combination of efficiency, ride comfort, tire performance, tire life and handling...for the 17" wheel?

I'm running 37 psi cold right now.
I keep mine at 39.5 cold. I used to keep all my cars around 41-42 but the mileage/wear tradeoff wasn't worth the ride stiffness & long term impact on the overall suspension degradation. I also don't take corners aggressively that much anymore & see very uniform wear with 5k tore rotations.

Some brands use a if memory serves me a different sidewall composition & those tires have a 51psi max inflation pressure.

My recollection isn't that the higher sidewall pressure is better just rather the sidewall is thicker or stronger so that allows for a higher pressure but that same sidewall also has lower compliance so the ride is less comfortable especially at max pressure.
