The French engineers had not been aware at first that the much admired German overlapping design had been motivated by a shortage of high quality rubber, necessitating large road wheels to lower tyre tension, which then were made overlapping to better distribute the load pressure.

Dilatant fracturing will create escape routes, so the fluid pressure is likely to be buffered at the value required for the transition between shear and oblique tensile ( dilatant ) fracture, which is slightly in excess of the load pressure if the maximum compression is nearly horizontal.

Switzerland is not a C . I . P . member state and therefore does not recognize any C . I . P . rulings and proofed its military 7.5?5mm rifles chambered in the GP 11 version of their service cartridge at 150 % of the GP 11 load pressure of 313.717 MPa ( 45, 500 psi ).
