It is shown how the tensor gravity makes the electromagnetic mass splitting of pions finite without using any lagrangian model for the strong interaction. The mass splitting is sensitive to the spectral-function sum rules. A finite mass splitting does not lead to a unique modification of the second Weinberg sum rule. For the electromagnetic mass difference of pions good values are obtained by suitably chosen input data.
