Question is 285 55 18 too wide or too tall?

Just bought some new wheels for my 69 shortbed fleetside. It has the original rearend and a 4/6 ECE drop. The wheels are 18 x 9.5 with a 4" backspace (distance from the back of the mounting surface to the inside edge of the rim) From what I can research the tire section width will be 11.8". The tire will be 30.6" tall.

Can anyone tell me if this will fit? Is it too wide or too tall?

Thanks,
CST350

Will look great on the rear, but will be too tall and wide on the front. Also, that bs won't work right on the front. I'm assuming all four wheels are the same size or are the widths staggered?

its going to be staggered... 255 60 17s on 8" with 4.5" backspace up front. Thats why I wanted to get the 285s out back so the tire profile will be taller than the front.
