Competency in Inspection, Repair and Replacement of Plant Equipment Tyres
This competency element focuses on the practical skills required to safely inspect, repair, and replace tyres on plant equipment such as excavators, loaders, and agricultural machinery. Learners will demonstrate the ability to identify defects, perform repairs on tyres and tubes, and document their work while adhering to health and safety regulations. Mastery of these tasks ensures operational efficiency and reduces downtime in heavy equipment operations.
Assessment criteria
Topic Overview
The IMI Level 2 Diploma in Specialist Tyre Fitting Competence is a vocational qualification designed for individuals working in or aspiring to work in the tyre fitting industry. It covers the essential skills and knowledge required to safely and effectively fit, repair, and maintain tyres on a variety of vehicles, including cars, light commercial vehicles, and heavy goods vehicles. This qualification is recognised by the Institute of the Motor Industry (IMI) and is a key step towards becoming a certified tyre technician.
The course is structured around practical competence and theoretical understanding. Key areas include tyre identification, fitting and balancing procedures, wheel alignment, tyre pressure monitoring systems (TPMS), and health and safety regulations. Students learn to use specialist equipment such as tyre changers, balancers, and alignment machines, and develop problem-solving skills to diagnose common tyre issues like uneven wear or vibration.
This diploma is crucial for ensuring road safety and vehicle performance. Tyres are the only contact point between a vehicle and the road, so proper fitting and maintenance directly impact braking, handling, and fuel efficiency. By mastering these skills, students contribute to reducing accidents and extending tyre life, making them valuable assets in the automotive service industry.
Key Concepts
Core ideas you must understand for this topic
- →Tyre identification: Understanding tyre size markings (e.g., 205/55 R16), load index, speed rating, and date codes to select the correct tyre for a vehicle.
- →Fitting and balancing: Using tyre changers to mount and demount tyres without damaging the bead or rim, and using balancers to ensure even weight distribution to prevent vibration.
- →Wheel alignment: Adjusting camber, caster, and toe angles to ensure proper vehicle handling and even tyre wear.
- →TPMS (Tyre Pressure Monitoring Systems): Knowing how to service vehicles with direct and indirect TPMS, including sensor replacement and reset procedures.
- →Health and safety: Following COSHH regulations for tyre repair materials, using PPE, and safely handling heavy wheels and tyres.
Learning Objectives
What you need to know and understand
- Be able to work safely when carrying out removal and replacement activities, Be able to inspect plant equipment wheels and tyres, Be able to carry out the repair and replacement of plant equipment tyres, wheels and tubes, Be able to record information and make suitable recommendations
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating correct use of PPE and adherence to safe working procedures during removal and replacement activities.
- Credit given for accurate identification of wear patterns, punctures, sidewall damage, and tread depth according to manufacturer specifications.
- Assess that the candidate completes a tyre repair to industry standards, including proper sealing and pressure testing.
- Recording information must include tyre condition report, work undertaken, and any recommendations for future maintenance.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always conduct a thorough visual inspection of both tyre and wheel rim before removal, noting any pre-existing damage.
- 💡Practice using tyre repair tools like plug insertion and patch fitting to build speed and accuracy under timed conditions.
- 💡Ensure your documentation includes vehicle identification, tyre size, issue found, action taken, and date/time, as this is a common assessment criterion.
- 💡Always refer to the manufacturer's data for torque settings and tyre pressures. Examiners look for evidence that you use technical data rather than guesswork.
- 💡When demonstrating fitting procedures, explain each step aloud to show your understanding of safety checks (e.g., checking rim condition, lubricating bead).
- 💡In written assessments, use correct terminology (e.g., 'bead breaker', 'run-flat tyre', 'dynamic balancing') to show depth of knowledge.
Common Mistakes
Common errors to avoid in your coursework
- Failing to properly deflate the tyre before removal, risking injury.
- Misdiagnosing tyre damage, such as mistaking a repairable puncture for a non-repairable sidewall injury.
- Incorrectly recording tyre pressure or omitting essential details in the job card.
- Misconception: Tyre balancing is the same as wheel alignment. Correction: Balancing corrects weight distribution around the wheel-tyre assembly, while alignment adjusts the angles of the wheels relative to the vehicle. Both are needed for optimal performance.
- Misconception: All tyres with the same size marking are identical. Correction: Tyres can have different load indexes, speed ratings, and tread patterns, which affect suitability for specific vehicles and driving conditions.
- Misconception: TPMS sensors are universal and can be swapped between vehicles. Correction: TPMS sensors are often vehicle-specific and require programming or relearn procedures after replacement.
