Knowledge in Inspection, Repair and Replacement of Standard Light Vehicle Tyres
This subtopic introduces foundational knowledge of standard light vehicle tyres, including relevant legislation such as the Road Vehicles (Construction and Use) Regulations and workplace health and safety procedures. Learners will explore the materials and construction of tyres, alongside the correct inspection, removal and replacement techniques using industry-approved tools and equipment. Mastery ensures safe and effective tyre maintenance, essential for entry-level vehicle service roles.
Assessment criteria
Topic Overview
The City & Guilds Level 1 Diploma in Vehicle Maintenance introduces you to the fundamental skills and knowledge required to work in the motor vehicle industry. This qualification covers essential topics such as vehicle systems, routine maintenance procedures, and workshop safety. You will learn how to inspect, service, and repair basic components of cars and light commercial vehicles, preparing you for further study or an entry-level role in a garage or dealership.
This diploma is designed for beginners with no prior experience in vehicle maintenance. It focuses on practical, hands-on tasks like changing oil, replacing brake pads, checking tyre pressures, and using diagnostic tools. You will also develop an understanding of how different vehicle systems—such as the engine, transmission, steering, and braking—work together. By the end of the course, you will be able to perform routine services safely and efficiently, following industry-standard procedures.
Vehicle maintenance is a critical skill in the transport sector, ensuring vehicles are safe, reliable, and environmentally compliant. This qualification provides a solid foundation for progression to Level 2 diplomas or apprenticeships in motor vehicle maintenance and repair. It also helps you develop employability skills like problem-solving, teamwork, and attention to detail, which are highly valued by employers in the automotive industry.
Key Concepts
Core ideas you must understand for this topic
- →Vehicle systems: Understand the main systems of a vehicle, including the engine, cooling, lubrication, fuel, exhaust, braking, steering, suspension, and electrical systems. Know their basic functions and how they interact.
- →Routine maintenance: Learn the schedule of checks and replacements required to keep a vehicle in good working order, such as oil changes, filter replacements, fluid top-ups, and tyre rotations.
- →Workshop safety: Always follow health and safety regulations, including using personal protective equipment (PPE), handling hazardous materials correctly, and using tools and equipment safely.
- →Tools and equipment: Identify and use common hand tools (spanners, sockets, screwdrivers) and workshop equipment (jacks, axle stands, diagnostic scanners) correctly and safely.
- →Inspection techniques: Develop the ability to visually inspect components for wear or damage, measure tolerances (e.g., brake pad thickness, tyre tread depth), and interpret service indicators.
Learning Objectives
What you need to know and understand
- Know about light vehicle standard tyre’s, legislation and special workplace procedures, Know about materials used in the repair of light vehicle tyres, Know about the inspection, removal and replacement of light vehicle tyres, Know about the tools and equipment used when working with light vehicle tyres
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for accurately identifying tyre size and speed rating markings as specified by ETRTO standards.
- Award credit for correctly listing key legislation, such as the legal minimum tread depth (1.6mm) and tyre condition requirements.
- Award credit for demonstrating safe use of jacking, supporting and wheel removal tools in accordance with workplace procedures.
- Award credit for describing the properties and purposes of tyre repair materials like plugs, patches and vulcanising solutions.
Assessment Guidance
Guidance for achieving higher grades
- 💡In practical assessments, always perform a thorough visual inspection of the tyre and wheel before removal, noting any damage.
- 💡When answering written questions, refer to the specific regulation (e.g., C&U regs) rather than just 'the law'.
- 💡Familiarise yourself with the exact names and uses of tyre repair kits, as assessors often test terminology.
- 💡Always refer to the vehicle manufacturer's service schedule or workshop manual for specific procedures and torque settings. Examiners look for evidence that you follow correct data rather than guessing.
- 💡When performing practical tasks, demonstrate a logical sequence: prepare the vehicle (isolate battery, chock wheels), gather correct tools, complete the task methodically, and then check your work (e.g., test brakes after replacement).
- 💡In written exams, use technical terms accurately (e.g., 'disc brake caliper' not 'brake thing') and explain the 'why' behind steps—e.g., 'I tighten wheel nuts in a star pattern to ensure even pressure and prevent warping the brake disc.'
Common Mistakes
Common errors to avoid in your coursework
- Confusing the legal tread depth limit for cars with that for motorcycles or heavy vehicles.
- Neglecting to check tyre pressure before inspection, leading to inaccurate tread depth measurements.
- Using impact wrenches to tighten wheel nuts without final torque check, risking over- or under-tightening.
- Misconception: You can use any oil in an engine. Correction: Engines require specific oil grades (e.g., 5W-30) that match the manufacturer's specifications. Using the wrong oil can cause poor lubrication and engine damage.
- Misconception: Tyre pressure is only important for fuel economy. Correction: Incorrect tyre pressure affects handling, braking distance, and tyre wear. Under-inflated tyres overheat and can blow out; over-inflated tyres reduce grip.
- Misconception: Brake pads only need replacing when they squeal. Correction: Many brake pads have wear indicators that cause a squeal when pads are low, but you should check pad thickness regularly (minimum 3mm) and replace before they reach the metal backing plate.
