Data sources and methodology
Manufacturer documentation
Our primary sources include manufacturer owner's manuals and technical documentation where available. These documents provide authoritative guidance on tyre pressure specifications for specific vehicle models, trim levels, and wheel sizes. We reference these sources to ensure our data reflects manufacturer recommendations.
Where direct access to manufacturer documentation is available, we use these sources to establish baseline values for typical pressure recommendations. This helps ensure our data aligns with official guidance where possible.
Industry and reference data
We also reference tyre industry references and reputable informational sites that provide tyre pressure guidance. These sources often aggregate information from multiple vehicles and help establish patterns and typical ranges for different vehicle classes and tyre sizes.
Cross-checking of values across multiple independent sources helps us identify common recommendations and verify consistency. When multiple sources align on typical pressure ranges for a specific vehicle and tyre size combination, this increases our confidence in presenting these values as typical recommendations.
Estimated and derived values
This site does not copy proprietary tables directly from manufacturer sources. Instead, we use typical values and rounded figures where appropriate. Our methodology involves synthesising information from available sources to present data in a simplified, easy-to-understand form.
Where exact specifications for specific vehicle variants are not available, we may use values derived from similar vehicles, same-model-year variants, or industry-standard ranges for similar vehicle classes and tyre sizes. This allows us to provide helpful guidance even when specific documentation is not readily available for every possible variant.
All values are presented as typical recommendations and are rounded to whole numbers for clarity and ease of use. The goal is to provide practical guidance that helps users understand what to look for when checking their own vehicle's specifications.
Ongoing updates and corrections
We aim to keep our data as accurate and up-to-date as possible. If you notice any discrepancies or have information that could help improve our data accuracy, please use our contact page to get in touch. We review feedback and corrections on an ongoing basis.
However, we always emphasise that users should verify tyre pressure information directly from their vehicle's official documentation or door-frame sticker, as these are the definitive sources for their specific vehicle.
