Bill Boards don't come with a modern rating like 295X50X15. It's an old school tire size thing that can only be roughly compared to the modern rating numbers.

Not sure about the back but the fronts could be roughly compared to a 255X60X15, I think they may be even bigger than that... As wide, perhaps not quite as tall.

At any rate, the Bill Boards are very nicely sized to each other and allow for a perfect "filling of the wheel wells" front and rear. Hard to beat the look by anything else.
