Tire

​

tire_pressure

• There are 4 data points with the same format, one for each vehicle tire, using the following names:
  • right_front_tire_pressure (right front tire pressure)
  • left_front_tire_pressure (left front tire pressure)
  • right_rear_tire_pressure (right rear tire pressure)
  • left_rear_tire_pressure (left rear tire pressure)

• Description: tire pressure
• Format: numeric
• Unit: psi
• Decimal places: 2
  • Data processed by mobway will always have at most 2 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 2 decimal places when the value ends in 0 due to automatic float formatting.
• Range: 14 to 150 psi
  • The minimum tire pressure value was defined based on atmospheric pressure, with an error margin. The maximum tire pressure value was defined based on the maximum value that vehicles connected to mobway can reach, with a safety margin.
  • Data outside this range is considered invalid.
  • The value is replaced with a null value.
  • A flag is generated indicating the error and the original value, in the following format:

{
  "right_front_tire_pressure": {
    "value": 255.00,
    "flag": "out of range"
  }
}

• Missing data
  • A flag is generated indicating that the original data was missing, in the following format:

{
  "right_front_tire_pressure": {
    "flag": "missing data"
  }
}

• Example:

{
  "right_front_tire_pressure": 32.45,
  "left_front_tire_pressure": 32.67,
  "right_rear_tire_pressure": 33.23,
  "left_rear_tire_pressure": 33.35
}

​

tire_pressure_status

• There are 4 data points with the same format, one for each vehicle tire, using the following names:
  • right_front_tire_pressure_status (right front tire pressure status)
  • left_front_tire_pressure_status (left front tire pressure status)
  • right_rear_tire_pressure_status (right rear tire pressure status)
  • left_rear_tire_pressure_status (left rear tire pressure status)

• Description: tire pressure status
• Format: categorical
• Values:
  • extremely low
    • Description: indicates that the tire pressure status is extremely low
  • very low
    • Description: indicates that the tire pressure status is very low
  • low
    • Description: indicates that the tire pressure status is low
  • nominal
    • Description: indicates that the tire pressure status is nominal
  • high
    • Description: indicates that the tire pressure status is high
  • unknown
    • Description: indicates that the tire pressure status is unknown
• Example:

{
  "right_front_tire_pressure_status": "extremely low",
  "left_front_tire_pressure_status": "very low",
  "right_rear_tire_pressure_status": "low",
  "left_rear_tire_pressure_status": "nominal"
}

ideal_front_tire_pressure

• Description: pressure recommended by the automaker for the front tires
• Format: numeric
• Unit: psi
• Decimal places: 2
  • Data processed by mobway will always have at most 2 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 2 decimal places when the value ends in 0 due to automatic float formatting.
• Range: 14 to 150 psi
  • The minimum ideal front tire pressure value was defined based on atmospheric pressure, with an error margin. The maximum tire pressure value was defined based on the maximum value that vehicles connected to mobway can reach, with a safety margin.
  • Data outside this range is considered invalid.
  • The value is replaced with a null value.
  • A flag is generated indicating the error and the original value, in the following format:

{
  "ideal_front_tire_pressure": {
    "value": 2.54,
    "flag": "out of range"
  }
}

• Missing data
  • A flag is generated indicating that the original data was missing, in the following format:

{
  "ideal_front_tire_pressure": {
    "flag": "missing data"
  }
}

• Example:

{
  "ideal_front_tire_pressure": 32.50
}

​

ideal_rear_tire_pressure

• Description: pressure recommended by the automaker for the rear tires
• Format: numeric
• Unit: psi
• Decimal places: 2
  • Data processed by mobway will always have at most 2 decimal places. However, the precision of the original data depends on the automaker. The data may have fewer than 2 decimal places when the value ends in 0 due to automatic float formatting.
• Range: 14 to 150 psi
  • The minimum ideal rear tire pressure value was defined based on atmospheric pressure, with an error margin. The maximum tire pressure value was defined based on the maximum value that vehicles connected to mobway can reach, with a safety margin.
  • Data outside this range is considered invalid.
  • The value is replaced with a null value.
  • A flag is generated indicating the error and the original value, in the following format:

{
  "ideal_rear_tire_pressure": {
    "value": 7.09,
    "flag": "out of range"
  }
}

• Missing data
  • A flag is generated indicating that the original data was missing, in the following format:

{
  "ideal_rear_tire_pressure": {
    "flag": "missing data"
  }
}

• Example:

{
  "ideal_rear_tire_pressure": 30.00
