Tire Load Index Check

The Tire Load Index Check substitutes your inputs (Load index per tire (kg), Actual axle load (kg), Tires per axle) into the standard expression: Axle capacity (kg) = Load index per tire (kg) × Tires per axle; Margin (− = overloaded) = Load index per tire (kg) × Tires per axle − Actual axle load (kg). Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Specify the vehicle specifications.

2. 2

   Step 2

   Hit "Calculate" and the result is computed automatically.

3. 3

   Step 3

   You can re-run the calculation with different values anytime.

4. 4

   Step 4

   Review the breakdown: the tire load index check shows each of your inputs substituted into the page's standard expression, so every variable stays traceable.

5. 5

   Step 5

   Compare scenarios by varying a single value per run in the tire load index check — that isolates which of the formula's inputs actually drives the result.

• 1

  The Tire Load Index Check needs every variable in consistent units — Load index per tire (kg) — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Round only at the end: Tire Load Index Check carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• 3

  Read implausible results with suspicion: if the Tire Load Index Check output sits orders of magnitude away from your expectation, re-read the inputs — a misplaced decimal or two swapped fields explains most nonsensical answers.

• Zero and negatives can sit outside the formula's domain: zero actual axle load (kg) may make the Tire Load Index Check undefined, and a negative load index per tire (kg) still returns a number. Check each input is inside the range the quantity allows.

• Load index per tire (kg) and Actual axle load (kg) must be entered in one consistent unit system: months against years skews the Tire Load Index Check result silently. Convert every input to the unit named on its field first.
