Look. It is true that they found the oldest war chariots with '
spoked wheel ' in Central Asia. But it doesn't mean that it is originally from there.
Those Sintashta chariots were dated ca
1700 - 1500 BC.

Those were YOUNGER than the Anatolian
spoked wheel war chariot !
And the oldest chariots that have been found are actually in Georgia. In Kurgans of Southern Caucasus, although as far as I know those oldest chariots they found didn't have '
spoked wheel ' .

I think about 4000 years ago the ' spoked wheels ' were the new technology of the ancients. That would mean that Yamnaya folks that invaded the Europe had chariots with '
solid wheels '. Late second PIE culture of Yamnaya was also not familiar with ' spoked wheels ' . Chariots of Yamnaya were identical to Chariots of Kurgans in Southern Caucasus (Georgia) and Mesopotamia. Yamnaya culture predate Sintashta culture at least by 1000 years. I mean there is a time frame of more than 1000 years between Yamnaya and Sintashta. They had at least 1000 of years of time to invent ' spoked wheels ' . This could be everywhere! That means that ' spoked wheels ' were either invented in Central Asia or on the Iranian Plateau (BMAC) or even the Yamnaya Horizon. The point is that EAST Iranian BMAC predate Sintashta by hundreds of years. I think that new technology came from the Iranian Plateau, because around the same time when
earliest spoked wheel chariot that has been found in Sintashta was almost of the same age as Hittites war chariots. Hittites were NOT Iranian or even Indo-Iranian people, but they were Anatolian people. The techniques that Sintashta folks used were heavily influenced by the older BMAC culture.
