Data Documentation
Last Updated: March 25, 2026
This document describes the data products available from Tire Scouter, including the sources, methodology, schema, and refresh cadence. It is intended for data consumers evaluating or using Tire Scouter datasets through data marketplaces or direct licensing.
Overview
The Tire Scouter dataset provides structured tire performance data, technical specifications, vehicle fitment information, and proprietary quality ratings (ScouterScore™). The dataset covers passenger car, light truck, and SUV tire segments across all major North American brands.
Data Sources
Our data is compiled from multiple authoritative sources:
- Manufacturer specifications — Dimensions, load and speed ratings, tread depth, warranty terms, and construction details sourced directly from tire manufacturer catalogs and spec sheets.
- UTQG (Uniform Tire Quality Grading) — Treadwear, traction, and temperature grades as reported to NHTSA under the federal UTQG program.
- Aggregated consumer reviews — Performance sentiment signals derived from publicly available consumer reviews across major tire retail platforms.
- Vehicle fitment databases — OEM tire size and fitment data mapped to year/make/model/trim combinations.
- Retailer product catalogs — Pricing signals and availability data from authorized tire retailers.
Methodology
Data Collection
Raw data is ingested from the sources listed above through a combination of structured feeds, public filings, and web-based extraction. Each record is tagged with its source and ingestion timestamp for provenance tracking.
Normalization
Tire specifications are normalized to a canonical schema. Brand and model names are standardized, dimensional values are converted to consistent units, and duplicate records from overlapping sources are deduplicated using a combination of UPC matching, manufacturer part number reconciliation, and dimensional fingerprinting.
ScouterScore™ Calculation
The ScouterScore is a proprietary composite rating that combines multiple performance dimensions—including wet traction, dry handling, tread life, comfort, noise, and snow performance—into a single normalized score (0–100). The score weights are calibrated using a blend of manufacturer test data, UTQG grades, and aggregated consumer sentiment. Tires are scored within their category (e.g., all-season, winter, performance) to ensure fair comparison.
Quality Assurance
Automated validation rules flag records with missing required fields, out-of-range values, or inconsistent cross-field relationships (e.g., a load index that does not correspond to the stated tire size). Flagged records are quarantined and reviewed before publication. Periodic manual audits sample published records against original source material to verify ongoing accuracy.
Data Schema
The core dataset is organized into the following tables / entities:
| Entity | Description | Key Fields |
|---|---|---|
| Tires | Core tire product records | tire_id, brand, model, category, size, load_index, speed_rating, utqg_treadwear, utqg_traction, utqg_temperature, tread_depth, weight, warranty_miles |
| Performance Ratings | Per-tire performance scores | tire_id, wet_traction, dry_handling, snow_performance, comfort, noise, tread_life, scouter_score |
| Vehicle Fitments | Vehicle-to-tire size mappings | vehicle_id, year, make, model, trim, oem_tire_size, bolt_pattern |
| Brands | Tire brand reference data | brand_id, brand_name, country_of_origin, parent_company |
Full schema definitions, including data types, nullable fields, and enumerated value lists, are provided alongside the dataset on each distribution platform.
Coverage
- Brands: 50+ tire brands including all major North American and global manufacturers
- Tire Models: Thousands of unique tire models across all-season, winter, performance, all-terrain, and specialty categories
- Vehicle Fitments: Coverage spanning model years from 2000 to present
- Geographic Focus: North American market (US and Canada)
Update Frequency
The dataset is refreshed on a regular basis:
- Specifications & fitment data: Updated quarterly as manufacturers release new products
- Performance ratings & ScouterScores: Recalculated monthly as new consumer data is incorporated
- UTQG grades: Updated as new NHTSA filings are published
Limitations & Disclaimers
- The dataset covers the North American tire market. Coverage of tires sold exclusively in other regions may be limited.
- Consumer review sentiment scores are derived from aggregated public reviews and may not reflect the opinion of any individual reviewer.
- ScouterScore is a proprietary metric and should not be interpreted as a safety certification or regulatory endorsement.
- Pricing signals are indicative and may not reflect real-time retail pricing.
