Looked up in a very old FM. Vref 40+55 is correct.
With a mass range of 110-170lbs we then get 177-208KN +5 KN wind we can expect the landing was at 182-213KN IAS
Assumed Wind - Actual Wind still unknown?

What is the Altitude based Ground Speed derived from 182-213KN?

Flightaware shows a Speed of ~210KN, and before touchdown one 184KN mark. I dont know what the speed value means on Flightaware.

Edit:
OK, FR24 showed Groundspeed of 211KN the seconds before touchdown, That is something!!!
Tyre Limit is 190KN?
