Checking and Maintaining Car Tyre Pressures and Tread
This element covers the essential practical skill of checking and maintaining car tyre pressures and tread depth to ensure vehicle safety and efficiency. Learners will develop the ability to correctly use a pressure gauge and tread depth gauge, interpret manufacturer specifications, and take appropriate action when tyres require inflation or replacement. Mastery of this routine maintenance task is crucial for personal safety, fuel economy, and legal compliance.
Assessment criteria
Topic Overview
The AIM Qualifications Entry Level Award in Employability and Development Skills (Entry 3) is designed to help you build the essential skills needed for the workplace and further learning. This qualification focuses on developing your personal effectiveness, communication, and teamwork abilities, which are crucial for success in any job or educational setting. You will explore topics such as self-assessment, goal setting, and problem-solving, all within a practical framework that prepares you for real-world challenges.
This award is part of the Foundations for Learning suite, which provides a stepping stone for students who may not yet be ready for higher-level qualifications. By completing this course, you will gain confidence in your own abilities and learn how to work independently and with others. The skills you develop here are transferable to many areas of life, including employment, further study, and daily activities, making it a valuable addition to your educational journey.
The qualification is assessed through a portfolio of evidence, meaning you will collect examples of your work to demonstrate your understanding and progress. This approach allows you to learn at your own pace and focus on areas where you need improvement. By the end of the course, you will have a clear understanding of your strengths and areas for development, as well as a plan for achieving your future goals.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly identifying the recommended tyre pressure from the vehicle's manual or door placard.
- Evidence must include the learner safely operating a tyre pressure gauge, recording both measured and target pressures, and adjusting pressure as needed.
- Assessors should look for proper inspection of tread across the central three-quarters of the tyre and at multiple points around the circumference, using a calibrated tread depth gauge.
- Learners must demonstrate safe working practices, including ensuring the vehicle is parked on level ground, with the handbrake engaged and engine off, before commencing checks.
- Award credit for correctly selecting and using a tyre pressure gauge to measure pressure, and a tread depth gauge to measure tread depth.
- Credit should be given for demonstrating the ability to adjust tyre pressure to the manufacturer's recommended level, referencing the vehicle's placard or handbook.
- Expect learners to identify legal minimum tread depth (1.6mm across central three-quarters of the tyre width) and check for uneven wear or damage.
- Evidence of safe working practices, such as ensuring the vehicle is on level ground, wheels are chocked, and the tyre is cold before checking pressure.
- For maintaining tyres, look for ability to replace valve caps, check for embedded objects, and report any defects to the appropriate person.
- Award credit for correctly locating the vehicle's recommended tyre pressure (e.g., from door pillar sticker or manual) and not relying on the sidewall marking.
- Award credit for demonstrating safe connection of the pressure gauge and accurate reading of the pressure (to the nearest PSI or Bar).
- Award credit for safely attaching the air pump, inflating to the correct pressure, and re-checking after inflation.
- Award credit for proper placement of the tread depth gauge at multiple points across the tread and correct interpretation of the reading against the 1.6 mm legal limit.
- Award credit for performing a visual inspection of the tyre, noting any cuts, bulges, or uneven wear patterns.
- Award credit for correctly replacing valve caps and tidying away equipment after use.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always refer to the vehicle’s owner manual or door jamb sticker for correct pressure specifications rather than generic assumptions.
- 💡Practice using both digital and analogue pressure gauges to become proficient with equipment variations encountered in assessments.
- 💡In assessment tasks, explicitly state the legal minimum tread depth (1.6mm) and demonstrate that you have checked this across the tyre.
- 💡Before the assessment, practice talking through the process aloud to demonstrate understanding to the assessor; use correct terminology like 'tread depth', 'inflation pressure', and 'valve stem'.
- 💡Always start the task by verbally confirming the vehicle is safely positioned and the handbrake is on; this shows the assessor your awareness of health and safety.
- 💡When checking tread depth, use the 20p test or a tread gauge and explain the legal limit; the assessor will be looking for both practical skill and underpinning knowledge.
- 💡After adjusting pressure, double-check with the gauge and offer to show the assessor the reading; accuracy is key to achieving the standard.
- 💡Always refer to the vehicle manufacturer’s recommended pressure, found on a sticker inside the door frame or in the owner's manual, not the tyre sidewall.
- 💡Before checking pressures, ensure the tyres are ‘cold’ (the vehicle hasn’t been driven for at least three hours) for an accurate reading.
- 💡When measuring tread depth, take measurements in several places across the tyre to identify uneven wear; clearly state if any part is below the legal limit.
- 💡Practise using both digital and analogue pressure gauges and tread depth indicators so you are comfortable with the tools likely to be provided during assessment.
- 💡Complete a full visual check of the tyre for damage before starting – look for cuts, bulges, embedded objects, and mention what you see to the assessor.
- 💡Maintain a clean and safe working area, showing awareness of hazards like trailing air hoses; this demonstrates good housekeeping and safety awareness.
- 💡Use specific examples from your own experience in your portfolio. For instance, if you demonstrate teamwork, describe a real situation where you worked with others, what you did, and what you learned.
- 💡Keep your evidence organised and clearly linked to the learning outcomes. Use a checklist to ensure you cover all required criteria, and label each piece of evidence with the relevant outcome.
- 💡Reflect on your progress regularly. Write short reflections after each activity, noting what went well, what you found challenging, and how you can improve next time. This shows deeper understanding.
Common Mistakes
Common errors to avoid in your coursework
- Confusing the recommended pressure for the spare tyre with that of regular tyres, or using the maximum pressure moulded on the tyre sidewall instead of the vehicle-specific recommendation.
- Overlooking the need to check tyre pressure when the tyres are cold, leading to inaccurate readings.
- Failing to check tread depth across multiple grooves and points, missing uneven wear patterns.
- Confusing pressure units: many learners incorrectly report PSI when the gauge reads BAR, or vice versa.
- Checking pressure when tyres are hot, leading to inaccurate (higher) readings and potential under-inflation.
- Misinterpreting tread wear indicators: learners may not realise a bald tread bar indicates the tyre is illegal and unsafe.
- Forgetting to firmly reseat the valve core after releasing air or failing to replace the valve cap, which can lead to slow leaks.
- Confusing the recommended tyre pressure with the maximum pressure moulded on the tyre sidewall.
- Not resetting the pressure gauge to zero before taking a reading.
- Measuring tread depth only at the centre of the tread rather than across the full width, missing edge wear.
- Forgetting to replace the valve cap after checking or inflating, leading to dirt ingress.
- Over-inflating the tyre without re-checking pressure after inflation, potentially causing uneven wear.
- Using a gauge incorrectly (e.g., not pressing firmly onto the valve stem) resulting in an inaccurate reading.
- Misconception: Employability skills are only about getting a job. Correction: While these skills help with employment, they also improve your ability to succeed in education, build relationships, and manage daily life.
- Misconception: Teamwork means always agreeing with others. Correction: Effective teamwork involves respectful disagreement and compromise to reach the best outcome, not just harmony.
- Misconception: Goal setting is just writing down what you want. Correction: Goals must be SMART and include a plan for achieving them, with regular review and adjustment.
