Competency in Inspection, Repair and Replacement of Plant Equipment Tyres
This element focuses on developing the practical skills and underpinning knowledge required to safely and competently inspect, repair, and replace tyres on plant equipment such as excavators, telehandlers, and agricultural tractors. Learners will apply industry-standard procedures for wheel removal, tyre and tube assessment, puncture repair, and refitting, while maintaining accurate records and advising customers on tyre condition and suitability. Emphasis is placed on compliance with health and safety regulations, manufacturer specifications, and the use of specialist tools to ensure operational reliability and minimise downtime.
Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in Specialist Tyre Fitting Competence is a vocational qualification designed for individuals working in the tyre fitting industry. It covers the skills and knowledge required to perform tyre fitting tasks safely and effectively, including tyre removal, fitting, balancing, and repair. This qualification is essential for those seeking to advance their career in motor vehicle maintenance, as it demonstrates a high level of competence in a specialised area.
The course is structured around practical assessments and theoretical knowledge, ensuring students can apply what they learn in real-world scenarios. Topics include health and safety regulations, tyre construction, wheel alignment, and customer service. Mastery of these areas is crucial for ensuring vehicle safety, optimising tyre performance, and reducing environmental impact through proper disposal and recycling.
This diploma fits into the wider Motor Vehicle & Transport sector by providing a pathway to further qualifications, such as the Level 3 Diploma in Tyre Fitting Management. It also enhances employability, as specialist tyre fitters are in high demand in garages, dealerships, and fleet maintenance operations. By completing this qualification, students gain a competitive edge and the confidence to handle complex tyre-related issues.
Key Concepts
Core ideas you must understand for this topic
- →Health and Safety: Understanding COSHH, PPE, and safe working practices to prevent accidents and injuries.
- →Tyre Construction: Knowledge of tyre components (tread, sidewall, bead) and their functions, plus tyre markings (e.g., speed ratings, load indices).
- →Fitting and Balancing: Correct procedures for mounting and demounting tyres, using balancing machines to ensure even weight distribution.
- →Repair Techniques: Identifying repairable damage, using patch and plug methods, and adhering to industry standards (e.g., BS AU 159).
- →Wheel Alignment: Understanding camber, caster, and toe angles, and using alignment equipment to adjust settings for optimal handling.
Learning Objectives
What you need to know and understand
- Demonstrate safe lifting, supporting and isolation procedures before commencing tyre work on plant machinery.
- Conduct systematic visual and tactile inspections of tyres, wheels and tubes to identify damage, wear and compatibility issues.
- Select and correctly use specialist tools and equipment for demounting, repairing and mounting plant tyres.
- Perform permanent puncture repairs and inner tube replacements in accordance with industry standards and legal requirements.
- Refit wheels securely, applying correct torque settings and following manufacturer bolt-tightening sequences.
- Accurately complete inspection sheets, job cards and customer reports, making evidence-based recommendations for tyre replacement or maintenance.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct positioning of axle stands, wheel chocks and isolation of power sources to create a safe working zone.
- Look for evidence of tyre pressure checks, tread depth measurement, sidewall examination and rim condition assessment during inspection tasks.
- Accept repair techniques that follow the published repair material manufacturer’s instructions and include the use of an inner liner patch and plug combination where applicable.
- Expect the candidate to reference the equipment operator’s manual when looking up torque values and tightening patterns, and to use a calibrated torque wrench.
- Marking should confirm that the candidate’s written or digital records include tyre identification codes, fitting dates, observed defects and actions taken.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the specific plant equipment’s manual for lifting points, torque settings and approved tyre specifications to demonstrate manufacturer compliance.
- 💡Use a methodical inspection routine that covers all faces of the tyre and wheel, including the inner bead area and valve stem, to avoid missing hidden damage.
- 💡When making recommendations, link your advice directly to evidence such as tread depth measurements, age-related cracking, or repeated punctures that exceed repair limits.
- 💡If possible, practise on a range of plant tyre types (bias, radial, foam-filled) to become familiar with different fitting techniques and tool requirements.
- 💡Always refer to the manufacturer's specifications for torque settings and tyre pressures. Examiners look for evidence that you can locate and interpret technical data.
- 💡In practical assessments, demonstrate a systematic approach: start with safety checks, then follow the correct sequence for each task. This shows competence and reduces the risk of errors.
- 💡For written questions, use technical terminology accurately (e.g., 'radial ply' instead of 'type of tyre') and explain the 'why' behind procedures, not just the 'how'.
Common Mistakes
Common errors to avoid in your coursework
- Failing to support the plant equipment adequately before wheel removal, increasing the risk of crush injuries or vehicle instability.
- Misreading sidewall markings, leading to fitting an incorrect tyre size, load index or speed symbol that compromises machine safety.
- Over-inflating a tyre after repair without placing it in a safety cage, ignoring the risks of explosive separation.
- Neglecting to document the work or not recording serial numbers, making traceability and future reference impossible.
- Misconception: Tyre pressure should be checked when the tyre is hot. Correction: Always check pressures when tyres are cold, as heat increases pressure and gives a false reading.
- Misconception: A puncture can be repaired with a simple plug from the outside. Correction: Proper repair requires removing the tyre, inspecting the inner liner, and using a combined patch-plug from the inside, as per industry standards.
- Misconception: Wheel balancing is the same as wheel alignment. Correction: Balancing corrects weight distribution around the wheel, while alignment adjusts the angles of the wheels relative to the vehicle and each other.
