You stated the bontrager wheels were 1720kgs, mr boon weighed the wheels and proved you wrong.....now go play with your meccano like a good little boy and let the adults talk properlyNo it doesn't, although I'm glad the op has now done a bit more research of their own.
It does indicate that my original stab in the dark of 2.2 kg was about right, and so to get down towards 8.5 Kg you've got to shed a kg off the wheels. Or more. Good luck!
