You can filter by specific vehicle (assetId) or group, specify inspection types, include location information, and apply pagination. This endpoint returns comprehensive tire condition information including pressure, temperature, wear measurements, and defect status. ## OpenAPI ````yaml /api-reference/smarttire.json get /public/v1/customer/{customerId}/asset/tire openapi: 3.0.1 info: title: public-api description: Public API Gateway version: '2025-12-17T15:30:00.000Z' servers: - url: https://public-api.masternautconnect.com/ security: [] paths: /public/v1/customer/{customerId}/asset/tire: get: tags: - /tire summary: Tire events description: >- Get the latest tire pressure and wear inspection data for one or more vehicles.
