Identifying Predominant stress criteria in Tire deformation

[Sriwardene]

In modeling of radial and axial deformation of tires, I basically look into von misses stress on critical areas in the tire,and most of the times, I do comparisons of mises stresses in different proposals than sticking into their magnitudes.
I would like to know whether there is any predominant stress criteria, specially in rubber models, which I should look into?

Thanking you

Rubbers fail in tensile strain, I think. I'd be using that if you can find no other source of information.

On the other hand bonded rubber bushes often fail at the rubber/metal interface, where presumably the strains are small. Hmmm.
