Our Methodology

How we collect, verify, and maintain accurate tire pressure data

Data Collection Process

Our Commitment

Every tire pressure specification in our database comes from official manufacturer sources. We never guess, estimate, or use crowdsourced data without verification.

Primary Data Sources

1. OEM Technical Documentation

We source data directly from manufacturer technical service bulletins, owner's manuals, and official specification sheets.

2. Vehicle Door Jamb Stickers

Official tire information placard data from vehicles, which displays recommended pressures for front and rear tires.

3. Manufacturer Databases

Access to official automotive manufacturer databases and technical service information systems.

4. Dealer Networks

Verification through authorized dealer service departments when manufacturer data needs confirmation.

Data Verification

Every entry in our database goes through multiple verification steps:

  1. 1.Source Verification: Confirm the data originates from official manufacturer documentation
  2. 2.Cross-Reference: Compare against multiple sources when available
  3. 3.Unit Conversion: Calculate and verify PSI to BAR conversions using precise formulas
  4. 4.Peer Review: Technical review by automotive professionals
  5. 5.Community Feedback: User reports help identify errors for re-verification

Data Structure

Each tire pressure entry includes:

  • Vehicle Make and Model: Specific brand and model name
  • Year: Model year the specification applies to
  • Tire Size: OEM tire size specification
  • Front Tire Pressure: Recommended PSI and BAR
  • Rear Tire Pressure: Recommended PSI and BAR

Update Frequency

New Vehicles

We add specifications for new model years as manufacturers release technical documentation, typically 3-6 months before the model year begins.

Corrections

User-reported errors are investigated within 48 hours. Confirmed corrections are updated immediately in our database.

Legacy Vehicles

We continuously expand our historical data, adding older vehicle specifications from archived manufacturer documentation.

Technical Service Bulletins

When manufacturers issue TSBs affecting tire pressure recommendations, we update affected entries within 7 days.

Quality Assurance

We maintain data accuracy through:

  • ✓ Regular audits of random database entries
  • ✓ Automated consistency checks for unit conversions
  • ✓ Community feedback integration
  • ✓ Professional automotive technician review
  • ✓ Comparison against official recall and TSB databases

Limitations & Disclaimers

Important Notice: While we strive for 100% accuracy, always verify tire pressure information with:

  • • Your vehicle's door jamb sticker (primary source)
  • • Your vehicle's owner's manual
  • • Your authorized dealer service department
