Could somebody advice, how to calculate ground preassure area on the truck wheel tyres in depend of the air preassure in the tyres and aplied load on the truck?
How to calculate deflection on the tyre and shape of the tyre before and affter applying a load?

RE: tyres
Thank you very much for your comment.
Now I'm sure that I hve to conduct particular test.
I thought that the tyre's manufacturers have done
some of the testing and have data I'm looking for,or are there some books I can find formulas to calculate ground preasure area under tyres.
However thank you again.
Sincerely,

Just jack up the wheel and lay a piece of square ruled paper under it and let it back down onto the paper. When you've jacked it back up and got the paper out, you can count the squares, but that will only be for the static condition. Tolerance abot +/- 5%
When you drive the contact patch gets smaller the faster you go, the slip to the road gets higher. Same if you drive in a corner, brake or accelerate, the lateral and longitudinal loading reduces the contact area.
The area you've got, the pressure is load through area.
Why do you want to know this? What are you trying to do?
