Overview
The Smart Tire API provides two ways to access tire pressure data:- Latest tire data - Get the most recent pressure readings for one or more vehicles using the Tire Events endpoint with
inspectionTypes=TIRE_PRESSURE - Pressure history - Get historical pressure events for a specific vehicle over a date range using the Tire Pressure Events endpoint
Pressure Measurements
Each pressure reading includes the following measurements:Why normalized pressure mattersTire pressure changes with temperature — approximately 1 PSI (6,895 Pa) for every 10°F (5.5°C) change. A tire reading 800,000 Pa at 45°C will show a different pressure at 10°C even if no air has been added or lost.Normalized pressure adjusts all readings to a standard 20°C (68°F) reference, allowing you to compare measurements taken under different conditions and accurately detect true pressure changes versus temperature-induced variations.
Pressure Alerts
The system automatically monitors for abnormal conditions and flags alerts:Pressure Thresholds
Pressure events include the configured thresholds used for alert detection:Event Data
Each pressure event captures a snapshot of all tire pressures at a specific moment:Pressure readings are typically captured while the vehicle is in motion. The
speedKph field helps you understand the operating conditions when the measurement was taken.
