GlennSter::: Based from my experience, 15X8 mags with 32 inch tires sagad na sukat na for stock suspension setup. Malapit na sumayad yung sidewall sa fender liners. But that's the difference of 2 inch shorter width of my old mags and taller tires compare to what you are using now. I'm just 10% sure if 32 inch muddies will fit in with 15X10 mags.
