driven wheel tractive force calculator online

Use driven wheel tractive force estimate online for engine torque Nm, gear, final drive, efficiency pct, tire radius m. Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.

How to use it

Enter engine torque Nm. Set gear, final drive, efficiency pct, tire radius m. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
engine torque NmMain input. Positive values. 250
gearOption. Positive values. 3.5
final driveOption. Positive values. 4
efficiency pctOption. Zero or positive values. Maximum 100.90
tire radius mOption. Positive values. 0.316

Calculation method

tractive_force_N = engine_torque_Nm*gear*final_drive*efficiency_pct/100/tire_radius_m (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply driven wheel tractive force estimate to the case below, keeping the displayed units and assumptions. Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.

Choose the right tool

Distinguish geometric estimates from measured vehicle performance. Tire rolling behavior, engine losses, charging curves and braking systems depend on actual conditions. Calculations do not establish fitment, roadworthiness or safe modifications.

Limitations and common mistakes

  • Idealized vehicle-system arithmetic using supplied measurements. This does not establish component suitability, safe modifications or actual performance.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
