Range and tire pressure

[zeusss]

So my service center filled up my tires(3lbs low) and my range improved drastically. I'm averaging 20wh less consumption since the visit. I had them fix a few small issues from delivery and they checked my Pirelli AS tires and filled them. They were technically warm so when the temp dropped a couple days later so did the tire pressure. I refilled them and the efficiency went back up. These AS Pirellis really need the 50psi cold pressure for efficiency. I know tire pressure makes a difference but 2-3 lbs seems wild to me for that kind of impact.

My understanding is that low tire pressure will definitely have a negative impact on range, but overinflation helps little if at all.

It needs to be "just right". Like Goldilocks lol

I keep something similar to this in the frunk just to manage tire pressure.

Yeah, I've got a Ryobi handheld unit. It looks like I'll be keeping a close eye on the tire pressure.

Does the Cybertruck monitor tire pressure for you? If not I wonder if a Tire Pressure Monitor System would be a good addition??

It does monitor pressure but doesn't throw an alert until its lower than this. So it's not dangerous but less efficient. In the winter efficiency starts mattering more.

I don't really understand that first sentence? your range actually improved with low tire pressure? I just topped mine off from 47 PSI to bring it back up to 50PSI due to the colder weather?

After they filled my tires my efficiency improved. I wasn't surprised at an improvement due to less rolling resistance with less surface pressure and so on... but rather how much it improved surprised me. I can't imagine how much difference AT tires with low pressure would hurt efficiency.
