I just found these links and thought I should share with you and others who may just want to have a glance. Tesla vehicles have it on their door jam to run their psi at 42psi or 45psi. That is on tires which have maximum psi of 50psi. They all say Tesla recommends this for maximum efficiency and best mpg.I set front 35 psi and rear 33 psi for the balance between highway cruise and handling.
I honestly don't know whether running higher psi is worth it. You risk having longer brake distance in emergency situations, and your tires risk uneven worn out...
You know Teslas are very high performance cars but also give great mileage. So, for the manufacturer to suggest those very high psi it means they know what they are talking about.
According to Tesla, the high psi gives best mpg and range. They are running their tires not at the maximum psi of the tire. 42psi or 45psi is lower than the max psi of 51psi, but still a high psi for someone like me who drives a Honda Accord where they recommend 33psi. I am running 36psi now and I believe it is not a high number per say. But I would love to experiment with 40psi on my next set of tires because that tire has a max psi of 51psi. This is what I plan to do to my car.
Tesla Model 3 high recommended oem psi of 42psi and 45psi...
Tesla high recommended psi across many years and models...
