Hi
Have idea to build 4x4 competition off-roader like hydrostatic hybrid.
Engine + hydraulic pump + accumulator + wheel motors.
Question = how much Nm needs 39'' agricultural tire to spin/start spin if it's fully entrenched into heavy wet clay or sand ?? (or how to calculate, or from where to found some info)
car weigh max 1500 Kg, tires 39'', wheel speed max 400 RPM
opinions at all - may there be a point, or is these just waste of time ??
(meaning - impossible to found parts with parameters I may need)
PS: First post - please don't kill me jet :) - English is not my home language

I know 250 Nm engine can do that with 1st gear (around 1/4) + transfer (1/2) + C303 portal axles (around 1/7)
250x4x2x7 = 14000
driveline loss with transfer and portals 50-60% ???
4500 Nm ?
