Pickup bed trailers have a pretty high empty weight. Mostly because people keep the heavy truck axle that is completely uneeded, well you need an axle and an idler axle would be fine and weigh around 1/3 of that of a drive axle.
What are these 45 to 55mph rated bearings and tires you seek of? If you buy dot approved highway tires and use an axle and hub with tapered cone bearings you would be fine.
I use 12'' rim load range E steel belted radial tires and I pull my trailer 75 to 85mph all day long.
My 4x8 trailer weighs less than 300 empty but is designed to hold 2,700lb.
Who is building this trailer?
Aerodynamics are irrelevant at 0mph when you're wheels fail.
