Here a picture of motor tpms . At the end about that they give pressure compensated to 20 degrC. Porche and BMW do it the other way around. They give recomended pressure for the setting, calculated from 20 degrC to the temperature in tyre, also sended by the sensors. But also here the psi...

Then list of cold at 20 drgrC and degrC it changes per 0.1 bar. See that we use comma ( ,) before decimals,UK probably uses dot (.) At 20 degrC/ degrC per 0.1 bar 1,5 bar/ 11,5 C/0,1bar 1,6 bar/ 11 C/0,1bar 1,7 bar/ 11...

Same here in the Netherlands, so cold measured in the shade will give minimal difference between 20 degrC measured. But if ever only can be measured in extreme ambiënt temperatures, calculate it roughly back to 20 degrC , and go from that. Yesterday it was 37 degrC here( in the shade. Then to...

There are 2 camps in temperature/ tyrepressure relation. The larger camp states that if for instance 40 psi is needed for the load and speed used, you have to fill or measure that at ambiënt temperature, be it 0 degr C / 32 degrF or 40 degrC/ 104 degrF. I am in the smaller camp together with...

But even with decent reserves in tires, it wont help if the pressure is not determined with decent reserve too

The loadindex for dualload axles is lower, because of roadcurve. Then inner tyre deflect more then outer tire. For tandem axle caravans you still use the single axle loadindex. But mayby more reserve is wisethen when single axle caravan. If towbar to high or low. More reserve to cover...

Can also be they damaged tire when mounting it. To high pressure is almost not possible. And to low gives problems after monts or years.

Lets wait what topicstarter comes up with. Mayby comfortable reserve with these tyres. But caravanmakers sometimes use tyres yust legaly enaugh, and then an upgrade is advicable. If final tyres are found, I can make a pressure/totalweight-list for them with maximum reserve,and still no screws...

What is the max permissable vehicle weight of your caravan, and if you can find it max permissable axleloads. The service descriptions 86T means maxload 530kg/1168 lbs a tire so would cover legaly an MPAW of 1060kg/2336lbs. But better is a reserve of minimal 10%. This tyre is most likely a...

The spreadsheet that opens directly in English, is in a submap of my motorhome- map in my public map of onedrive that belongs to my hotmail.com adress with usernane jadatis ( like this to prevent spamm) From thete you can navigate the complete public map...

Came to this forum, and registered to give tyrepressure-advice. Got hold of the official European formula to calculate it from standards manual 2007 page 14 vv of ETRTO , and went running with it. Got wiser in time bij nagging people who knew more about it. In spreadsheets I made for it ...
