The hub is 2.5" in width, 5" long, the tire, 1.5". Spokes on the tire side are centered. Spokes on the hub side are offset.
Horse drawn wagons large or small had what is called "Proper Dish". Dish creates a truss-like situation in the wheel when the wagon is turning.
Take a look at the bottom image of the link, the two carpenter squares, the arch of the axel, etc.

My little hard cart is verticle, not expected to carry more than I can push or pull. In this case, it's only as good as the driver, but I'm sure I could carry a keg of beer well enough.
As for the spokes on the wheels, I just guessed. Thought I could make a lighter wheel, then just heavy wood ones.
Edited: I've often thought, in my ODA time down range, how a cart could be used in a small village, what ecomony of motion/trade, good will could be had, if I had made a few carts for children, families, the village women or farmer.
I fixed a few carts in Thailand, made also a floating tool box for a farmer. I lashed a wood pallet to an inflated tractor tube to float across his rice paddy. Out in the middle of his field, was his house. Carrying tools, supplies from the road was a chore.
The new device, saved him a lot of time and effort, giving us more time to talk and discuss the region.
