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.Source Verification: Confirm the data originates from official manufacturer documentation
- 2.Cross-Reference: Compare against multiple sources when available
- 3.Unit Conversion: Calculate and verify PSI to BAR conversions using precise formulas
- 4.Peer Review: Technical review by automotive professionals
- 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
