Lesson notes

Learning Objectives

Indicator: 2.1.2.LI.6 - Describe vehicle wheels and tyres.

By the end of the lesson, learners can:

Identify and label the major parts of a vehicle wheel and a tyre using sketches, charts, or real objects.
Classify different types of wheels (disc, wire-spoked, and split-rim) and types of tyres (cross-ply, radial-ply, tubed, and tubeless) by their construction and appearance.
Explain the function of the wheel and tyre assembly, including how it supports the vehicle load, transmits driving and braking forces, and absorbs road shocks.
Compare the advantages and disadvantages of radial-ply versus cross-ply tyres, and tubed versus tubeless tyres, using justifiable criteria.
Read and interpret the basic markings on a tyre sidewall (size, ply rating, and pressure rating) and state the correct tyre pressure for a given vehicle type.

Groupwork/collaborative learning Guide learners using relevant sketches, charts or real object to discuss the different types of wheels and tyres. Experiential learning : Learners visit a local repair workshop or a retail shop and observe critically the various types of vehicle wheels and tyres, tyre servicing and repair and present their report.

Assessment (2.1.2.AS.6). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.
