Tire Pressures and Temps

Howard · Host

All temps and pressures are in normal ranges after being driven.

Of course the only way to know the proper starting pressures for all the tires is to know what load they are carrying. But with the knowledge you have until you can get weighed wheel-by-wheel, the changes in your pressures are normal (around 10 - 15% of starting pressure). If your tires are underinflated for the load, temperatures will increase above normal and, therefore, so will pressures.

As for temperature changes, those are normal too. Keep an eye out for significant temperature changes on one wheel compared to others and for any temps approaching 200 degrees.

At first the temperature in the tire can be different from the temperature of the treath you measure .

The temperature in the tire can rise to boiling point of water at 1 bar=100dg C/??F.

And this is indeed because of the heat of the brakes , transported trough the rimms to the tire-inside.

Sorry , in Holland where I live, we use Kg , Bar , and degr Celcius , so you have to convert it yourselves.

I made a spreadsheet to play with the temperature in the tire, and see what it does to the pressure.

On my skydrive from hotmail I planted the spreadsheet , click right on the "pressurecalculation with temp "and pick "download".

After that open it in Excell or compatible programm.

Moderator note and question:

Since I know nothing about "Skydrive" nor the forum participant that posted the above comment with a link to a Skydrive source, I would like to know if anyone knows anything about whether there have ever been computer "virus" issues with Skydrive.

While I might be interested in the information in "jadatis's" program, I have no intention of downloading anything until I know more about both Skydrive and jadatis's downloadable file.

Should anyone know of virus issues with Skydrive or anything else about jadatis's file, kindly let me know so that I can decide whether to leave his comment or not. After all, this is jadatis's only post at RV Dreams.

Skydrive appears to be Microsofts response to Google docs a place to put things.

The real question is the Excel spreadsheet you have no idea what you may be getting into unless you know the source you're getting it from. I don't know the poster well enough to say trust don't trust. How good / current is your virus scanner?

There are a number of tire presure / temp charts out there on the web.

Thanks Howard. That was about what I figured but was just verifying. Getting a wheel by wheel weighing is on our list of things to do but will have to wait until we run into you on our travels or hopefully the New Horizons Rally will have somebody on hand next spring that can do it. I assume there are others that also do wheel by wheel weighing but haven't run across any yet.

I probably registered a while ago , to give answer to a tire-pressure related question, but did not do the answer , so this was my first post here.

I am frequently googling for tire-pressure , because I once got hold of the formula that the tire-makers in Europe use , and went running with it.

I live in Holland.

Learned myself Excell with help of different furum users , and made spreadsheets for it. Translated a few to English to go worldwide with it.

Skydrive is what you can use when you have a Hotmail adress and I planted many files on the public map of it to refer to in fora.

Problem is that they constantly chanche the lay out of it , so downloading from it needs an other way in time.

But when you download a document of it, you can first do a virus check before opening it.

You can also open some Spreadsheets in the browser, but this cant handle sheetprotection annd data validation, that I use in most spreadsheets.

Sheetprotection to prefent overwriting formulas, and data validation to make dropdown-boxes to select for instance the loadindex with their weights in kg and lbs.
