Tyre pressure data accuracy

The tyre pressure values on this site are derived from typical ranges by vehicle class, tyre size, and example values seen across multiple independent sources. We use typical cold tyre pressure values, which are the recommended pressures when tyres have not been driven on for at least a few hours and have reached ambient temperature.

Our data collection involves reviewing manufacturer owner's manuals, technical documentation where available, and cross-referencing with tyre industry references and reputable informational sites. We aim to present values that reflect common recommendations for each vehicle model and tyre size combination.

Not all models, trim levels, and tyre combinations can be perfectly represented in a general reference guide. Tyre pressure specifications can vary based on:

• Specific trim level or variant
• Exact wheel and tyre size fitted to your vehicle
• Load conditions (normal load vs. full load)
• Year of manufacture and any mid-cycle updates
• Regional specifications and market variations

The values are structured to match common handbook patterns, but your vehicle's exact specifications may differ. This is why we always emphasise checking your own vehicle's official documentation or door-frame sticker.

Always follow the label in your vehicle first: The most reliable source of tyre pressure information for your specific car is the sticker on your driver's door frame, inside the fuel filler cap, or in your owner's handbook. These sources provide the exact pressures recommended by the manufacturer for your particular vehicle.

Check when tyres are cold: Tyre pressures should be checked when tyres are cold—meaning the vehicle hasn't been driven for at least three hours or has travelled less than a mile. Cold pressures provide the most accurate readings and are the basis for all manufacturer recommendations.

Adjust for heavy loads and motorway use: When carrying heavy loads or embarking on extended motorway journeys, you may need to increase tyre pressures according to your vehicle's handbook. Many vehicles specify different pressures for full load conditions, and your door-frame sticker will typically show these values.

Use this site as a helpful reference tool to understand typical pressure ranges, but always verify and follow the manufacturer's guidance specific to your vehicle for optimal safety and performance.
