Someone correct me if I'm wrong, but I don't think the same size tires from different companies will result in a different rolling diameter. What will differ is the actual tread width and sidewall shape. For example, one company's 285 width tire may be rounded/tapered more at the edges and/or have a smaller tread contact patch than another company's 285 width tire (although the overall widths are the same)--a tire with a more rounded/tapered sidewall will be less likely to rub b/c it will taper at the fender area.
