I need some real mud tires with lugs to get me out of some sticky situations with the Roxor. I found this chart that helps with the width decision but have asked around for more rim specifics as to offset etc . https://www.tyresizecalculator.com/charts/tire-width-for-a-wheel-rim-size-chart .Also thinking about these Federal Couragia in a 265. https://simpletire.com/federal-lt265-75r16-46fe64fa-tires
