title: Reply to "comment on nonlinear viscosity and Grad's method ".
abstract: We show that while Eu's claim is true that we made a mistake regarding the asymptotic behavior of his theory is true, the correct asymptotic behavior cannot have a physical meaning. We analyze in more detail his theory for a dilute gas of rigid spheres, and show that in some cases it predicts a negative value of the xx component of the pressure tensor.
