@Genava55, lovely, thanks a lot! (Spoilers would be nice, though. )
While historic reenactors can occassionally provide valuable insights, popular videos ought to be used with caution. Generalizing and drawing conclusions on the basis of a single sample is a slippery slope. Yes, Egyptian chariots tended to be light and nimble, but equating them to the Middle East goes too far. Just look at some of the examples I posted earlier. Chariots with the axle below the middle of the basket, below the back, or somewhere in between are known from the Near East. Assyrian chariots had rectangular baskets too and crews of two, three, or four. As for the number of spokes, four, six, and eight are common, but seven, nine, ten, and twelve are also known, and probably a few other numbers; if many-spoked wheels were intrinsically better, then surely people elsewhere would have figured that out; the number of spokes appears to be more a local preference, if anything. Wheel diameter wasn't constant either, some had quite small wheels, others were much larger. One has to keep in mind chariots were not mass-produced.
More important than those differences are the more fundament similarities: a single axle with spoked wheels and a single pole with horses on either side.
Sorry, I'm not quite sure what you meant. Chariots had spoked wheels, but solid wooden wheels continued to be used, e.g. moveable siege towers.
