Once you determined the cold pressure needed for the speed and load on tyres, with maximum reserve at wich comfort and gripp is still acceptable, you can let the cold pressure flow with ambiënt temperature. At least that is the conclusion of this pigheaded Dutch selfdeclared tyrepressure...

When filled 42 psi at 82 degr F, it drops to 37 psi at 38 degr F. If filled with normal air with maximum humidity. If you fill at 68 degr F. the needed pressure you can let it flow with temperature change, is my conclusion in time, and will be proven right in about 20 years Main goal of pressure...

2 systems for tmps sensors. 1. Waking up by a signal sent from receving unit, then even when not driving, mayby after a minute or so, the pressures of that morning. 2. Waking up by movement of the sensor, then you can try to tap the valves to suggests movement to the sensors. So you have to...

Made a tyrepressure/temperature calculator for dry gascompound in tyre (fi Nitrogen filling) and Wet (normal air), in that last I am first, I think. In this RV map So play with it, also part 5, and see that the influence of water in tire is often exagerated by the Nitrogen-lobby. So if you go...

This shows that tirepressure has minimal effect on energy use. At lower speed lesser windforce, so energyloss by tires is relatively more then at higher speed. At 75mph the tire produces a little less heat ( so energyloss) per rotation. per 100miles/kilometers then a little lower energyloss...

You could try out first, to lower the pressure with use of my list. Mayby that is already enaugh for better comfort. And mind that wider tyre needs wider rimm. I made rimmwidth calculator, after contact with Vredestein, and uses ratio's from desighners guide of ETRTO. Also aspect ratio is...

Some feedback after a while would be nice. About energy-use, comfort and tyre-wear. I suspect for people with a heavy foot, to give lesser tyrewear, because better gripp, so lesser slipping. And if you have other size, first look in the other topic if already given, and if not, give loadindex...

First googled the size, and only found XL in 102 loadindex. So your tires are LI 102 / maxload 850kg/ 1874 lbs AT 42 psi ( 2.9 Bar) upto 99mph/160kmph. Official system is Y upto 220kmph/??mph but this " pigheaded Dutch selfdeclared tyrepressure specialist" dont believe that, so keep using...

That list in former post is calculated with a safe formula, but no reserve build in, and is for max 160kmph/99mph. In the lists I make and given in the topic I linked to in my first post here, I use an even safer formula that leads to lower loadcapacity for the pressure, and give 90% of that...

I dont believe Tesla spent a lot of effort in tire pressure recommendation, yust high for high actiradius, and that comfort and gripp sucs then, they dont care about. Did you have mayby indirect low pressure message in your former cars? They can be reset even if you give all tires much to low...

Look at this topic, in wich I give lists and explanation. Change of tyre pressure if using 255/50/19 107Y due to higher load rating But tmps alarm is a secundary problem. Porche uses lower alarmsettings if comfort setting used. Mayby Tesla too. Once the signal of sensor is receved in the...

XL LI 104 / maxload 900kg/1984lbs AT 42 psi upto 160kmph/99mph Kg axleload/cold psi/ Lbs axleload 835 kg/ 20 psi / 1842 lbs 872 kg/ 21 psi / 1922 lbs 908 kg/ 22 psi / 2002 lbs 944 kg/ 23 psi / 2082 lbs 980 kg/ 24...

Now for 101 loadindex /maxload 825kg/1819 lbs. AT 42psi so XL KG axleload/cold psi/LBS axleload 766 kg/ 20 psi / 1689 lbs 799 kg/ 21 psi / 1762 lbs 832 kg/ 22 psi / 1835 lbs 865 kg/ 23 psi / 1908 lbs 898 kg/ 24 psi...

Joined in an other topic on this forum, and pointed to this topic. Was in the UK and Ireland part, so will give the lists for KG and LBS. 1 or 2 years ago Continental introduced the HL for High Load especially for the heavyer electric cars. Is a tire with about 3 loadindex steps higher then...

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...
