edit:

i wont discuss that outlaw but then friction is surface INDEPENDENT for rigid objects as boxes and surface DEPENDANT for soft objects like tyres

so actually the right answer for my question:

is frictiion surface dependant?

the right answer is yes and no

edit:

otlaw your so gonna love this:

if i google:

3 point of contact friction

this thread makes it 7th of 5.400.000

so either google has me on high steem or this is not such widely known idea
