Tractor Pulling Tyre Dynamics
Tractor Pulling Tyre Dynamics
(OP)
Please can someone provide formulae that explain the very high drawbar pulls that can be generated by competition Pulling Tractors. I am aware of cut down tread lugs and tyre peripheral speeds of maybe 200 mph. Is it some form of energy transfer from speeding up hunks of clay?

It's the combination of the tire and weight transfer. Even a bald tire can get quite a bit of traction if loaded down enough.

However, my first guesses are that "something" is adding maybe 100% to the drawbar pull obtainable from friction on moist clay..
That is allowing for weight transfer effects and pulling chain angles
Some mathematics would be most welcome...
