##### Abstract

The tetra-maximal neutrino mixing pattern predicts a relatively large reactor
mixing angle theta_13 \approx 8.4^\circ, which is in good agreement with the
latest best-fit value theta_13 = 9^\circ. However, its prediction for theta_12
\approx 30.4^\circ is inconsistent with current oscillation data at the 3sigma
C.L. We show that explicit perturbations to the tetra-maximal mixing can
naturally enhance theta_12 to its best-fit value theta_12 = 34^\circ.
Furthermore, we demonstrate that if the tetra-maximal mixing is produced by a
certain flavor symmetry at a high-energy scale Lambda = 10^14 GeV, significant
radiative corrections in the minimal supersymmetric standard model can modify
theta_12 to be compatible with experimental data at the electroweak scale
Lambda_EW = 10^2 GeV. The predictions for theta_13 \approx 8.4^\circ and
theta_23 = 45^\circ, as well as the CP-violating phases rho = sigma = -delta =
90^\ciic, are rather stable against radiative corrections.
