MYLR tyre pressure

It’s not uncommon when preparing a car for a long transport journey to overinflate the tyres. Tesla gets poor marks for pre-delivery checks, which sadly they deserve.
Also, if they were set when ambient temp was very low (not today but there have been some very cold mornings quite recently) you would see a higher "cold" reading since the temps have come up. Keeping an eye on pressures and compensating for this is a normal thing to do with your car (any car). Of course it's made more obvious when the numbers are so readily available!

I was going to make this point. I set mine to like 41-42 while cold in December and noticed on a long journey yesterday they were showing 45-47 while diving with an ambient temp of 13 degrees.
Dontblowervthevpressure in the blind, you risk using to low pressure for the axleloads and speed used.
Then the most important is that you determine the axleloads in your use acurately, the most tricky part in it all, and your responcibility.
Most accurate is by weighing per axle in the loading you use, so persons and load in it.
Then yoin in next topic, where I give several pressure/ axleloadcapacity- lists with maximum reserve, but still acceptable comfort and grip.
Change of tyre pressure if using 255/50/19 107Y due to higher load rating

Mine stay between 41-44. Ride is fine on 18s. The tyre profile (sidewall height) will make a big difference to ride too.
If just me, 39 is optimal for ride without it setting off the low pressure warning symbol. It then increases to about 42 on a > 30 mile run.
If with family or other load, then I set to 40. Again, reaches about 42-43 per the screen - not sure what the actual calibrated pressure is.
It helped reduce the crashiness of the ride a little, but the improved steering feel was more noticeable.
