Well that's what I want to know. I don't understand the 285/75. Not sure how that reads and what dimensions it covers. Getting new tires and I want to Upsize from 31's to 33's. Also if you could help what is the best fit size wheel for a 33? I have 15x7 on truck now, but looking at getting some new rims anyways. Would a 15x8 or 16x8 work? Or do I need bigger? Or would a 15x7 Even work. When I say work I mean Work with Safety first in mind. Thanks
