Tyre swell or ballooning isn't as big a speed gain as you might imagine, as they ballon traction decreases meaning high speed slippage.

Nice work on the raw numbers btw, its intresting to put a figure on the potential differences between the gearing options, they really don't seem to add up to a whole lot. In reality you have to be careful with overgearing a vehicle, even with a big enough runway the engine may not have the high rpm torque to fully spool out if the gearing is too high, and a similar setup with lower gearing can actually have better top end.
