I have a 2015 SR5 with Bilstein 5150 and OME rear Springs running 32.76" Nitto Ridge Grapplers on stock 17x7 rims. My question is, do I need to re-gear? I also have full RCI plating, LFD Roof Rack, and SSO Rock Sliders so some added weight but not a ton... I'm currently getting between 15-17 mpg... Would there be any mpg benefit to re-gearing?
