We probe the limits of nonlinear wave spreading in disordered chains whichare known to localize linear waves. We particularly extend recent studies onthe regimes of strong and weak chaos during subdiffusive spreading of wavepackets [EPL {\bf 91}, 30001 (2010)] and consider strong disorder, which favorsAnderson localization. We probe the limit of infinite disorder strength andstudy Fr\"ohlich-Spencer-Wayne models. We find that the assumption of chaoticwave packet dynamics and its impact on spreading is in accord with all studiedcases. Spreading appears to be asymptotic, without any observable slowing down.We also consider chains with spatially inhomogeneous nonlinearity which givefurther support to our findings and conclusions.
