You know, it might be interesting if someone actually looked up whether or not the chariot wheels were made entirely of wood or if the Egyptians used metal. I bet we could find out. If it was metal maybe one would expect to find some rusty remains, but if of wood, forget it, there would be nothing by this time.
Furthermore, where are all the other chariots down through time? Has a single chariot survived otherwise?
On the other end of the EVIDENCE, though, the dating for the Exodus per the Bible now coordinated with astronomical texts show the king who would have died in the Red Sea was Amenhotep III. His mummy is the most mangled of all the mummies even being beheaded and with a special process introduced with them in an effort to restore missing flesh. There were fractures of both legs beyond the beheading and a crushed in chest. Was this done by grave robbers or was the original recovered body traumatized? The net has information about the mummies and the details including Amenhotep III. The condition of Amenhotep III's body is not conclusive but consistent with his dying in the Red Sea.
Anthropologically, Akhenaton's focus on monotheism, perceiving a god that insisted on no image being made of him and outlawing all the gods of Egypt sounds like a post 10-plague "epiphany" if ever there was one, especially since we can reliably coordinate the dating via an astronomical text (KTU 1.78).
Did the chariots of Amenhotep III's time have metallic parts? Or were they all wood?
