I've always followed the cars recommendation of 36. Looking at the tires they can goto 44 max. Not sure I would want to run the tires at max psi to save a few cents on my power bill. I simply drive it like I drive any other car. I know some folks baby their ev to get better range, and that's fine. But that is not me.
36 is the recommendation for "regular" use. Do you add 2 PSI every time you have 4 adults in the car? Reduce the pressure back to 36 PSI for your solo commute to work?
If the answer to either of those questions is a "no" then you are not really following any recommendation completely.
As far as saving money on the power bill? I don't understand that statement at all nor will most EVers. Peruse this forum. You will soon see that many here don't even know what the impact to their power bill is. Yeah, it is that small. But lets talk about extending range. Now there is a lot there to digest and one of the easiest things to do is add tire pressure. It WILL boost your range. Now, you might think you have all the range you need and its your car, your tires. Your choice is not invalid nor is it optimal. Not everyone cares about optimal.
Personally I do the 44 or... rather I should say "43" which is what mine are set to, out of pure laziness. I selected 43 immediately after my "Winter adjustment" because I simply aired up all the tires to what I felt was about right and then spent 3 days adjusting them exercising the minimal effort required by deciding my set point on the lowest pressure of the 4.
This will do. I will lose 5 feet or even 10 feet of stopping power but due to my driving style and EXTREME use of regen, this won't be an issue. I could lose 20 feet of stopping power and that wouldn't be an issue either since I always drive with the idea of using regen in B mode for 98% of my deceleration needs. Of course, there are times when time is of the essence so E Pedal covers 1.98% of the situations B mode cannot safely handle. As far as braking on the freeway? Since Feb 2018 to now, I have touched my brake pedal twice that I recall of which was a full stop from 70 mph coming downhill on the 405 just north of Bellevue because someone thought it best to come to a stop on the freeway for debris instead of driving around it like everyone else did. This only obscured my vision of the issue. That happened on my maiden voyage home.
Now, I check my tire pressure EVERY morning within the first 2-3 minutes of my drive. Do you? Its so easy now I wouldn't understand why anyone wouldn't perform this basic check? I also check it after any extended time in a public parking lot. Paranoid? Maybe. Stranded from a flat tire? Yes, but not in the last 42 years. Have had slow leaks? Dozens! My 2010 Prius got 4 of them within 4 months due to construction surrounding me. I simply aired up the tires when they dropped below "about" 35 PSI or so pumping them up to 60 PSI. Lasted more than a week like that until I finally got around to getting the tire patched.
My LEAF's have had a few as well. LEAF Spy helped out with that as I soon discovered the "idiot" lights on older LEAFs don't come on until the pressure is in the mid 20's :shock:
(No, I did not accidentally allow my tire to get that low. I actually removed air when my leaking tire was down to the low 30's to see when the light would come on...) Makes it quite easy to see how they got their name...
It will be interesting to see how many miles you get from your tires.
