Most tire/wheel shops have a big selection of ROTA mags. You just have to look around. In the south, Minerva (Alabang, Binan) has quite a few, in Q.C. or the Banaue area, almost every other wheel shop carries the current ROTA line-up. For some models, though, you have to order, as ROTA's books are filled due to increasing demand in the US.
