  1. Wheels andTyres

  2. Radial Ply Tyre – the main plies of the tyre run at 90 degrees from one bead to the other. Cross Ply Tyre – the main plies of the tyre run at 45 degrees from one bead to the other. Plies – Layers of strong fabric which are built up to give the tyre its strength and shape Bead – loops of steel which are the anchorage point for the plies. Tread – this provides the grip with the road surface, the pattern assists in clearing any water away Side Wall – this connects the beads to the tread of the tyre. Terminology • Steel Wheels – A very popular design of wheel. Very strong and cheap to produce. • Alloy Wheels – Attractive and light weight, but can be difficult to clean. • Spoked Wheels – Used on older sports vehicles, but cannot be fitted with tubeless tyres. • Divided rims – the rims are made in two halves which are bolted together, the rims must never be separated while the tyre is inflated. • Split rims – the tyre is held in place by a large circlip, do not remove the tyre unless you have been properly trained www.cctyrespenrith.com.au

  3. Rim Centre mounting section Wheel - Basics Most standard wheels are made of steel. Some vehicles are fitted with alloy wheels that are made of magnesium or aluminium. The rim holds the tyre. The well of the wheel allows the tyre to be removed and refitted The centre section is welded to the rim. The pilot bore fits to the hub. www.cctyrespenrith.com.au

  4. Taper Wheel mounting Hub flange Wheel Fixings Wheel studs and nuts attach the wheel to the hub. The wheel studs press through the hub or axle flange. The taper on the wheel nuts secures and centres the wheel. Wheel studs usually have a right-hand thread. If it is a left-hand thread, it can be marked with “L”. Metric threads can be marked with “M” or METRIC. www.cctyrespenrith.com.au

  5. Wheel Nut Torque Correct torque of wheel fixing is vital for all vehicles, and nearlyall require the use of a torque wrench. Excessive torque can lead to wheel or hub distortion, causing runout and vibration. Low torque may allow wheel nuts to work loose and wheels to come off. Nuts should be tightened in a diagonal pattern. Torque wrench www.cctyrespenrith.com.au

  6. Tyres (Introduction) • Basis Functions • The tyre acts as the primary suspension, cushioning the vehicle from the effects of a rough surface. • It also provides frictional contact with the road surface. • This allows the driving wheels to move the vehicle. • The front tyres allows the wheels to steer . • The tyres allow the brakes to slow or stop the vehicle www.cctyrespenrith.com.au

  7. PneumaticTyres • The tyre is a flexible casing, which contains air. • Tyres are manufactured from reinforced synthetic rubber. • The tyre is made from an inner layer of fabric plies, which are wrapped around bead wires at the inner edges. • The bead wires hold the tyre in position on the wheel rim. • The fabric plies are coated with rubber, which is moulded to form the side walls and tread of the tyre. Behind the tread is a reinforcing band, usually made of steel,rayon,or glass fibre. Modern tyres are mostly tubeless, so they have a thin layer of rubber coating inside to act as a seal. www.cctyrespenrith.com.au

  8. Tyre Construction • Cross – ply tyres are not used on any mass produced modern cars. However, the construction details are useful to show how tyre technology has developed. • Several textile plies are laid across each other, running from bead to bead in alternate directions. • The number of plies depends on the size of the tyre and the load it has to carry. • The same number of plies is used on the crown and the sidewalls. www.cctyrespenrith.com.au

  9. Tyre Construction • Radial – Ply tyres consist of a carcass ply formed by textile arcs running from one bead to the other. • Each ply which is laid in an arc at an angle of 90 degrees to the direction the tyre rolls. • At the top of the tyre crown (under the tread), there is a belt made up of several plies reinforced with metal wire, laid on top of the carcass ply. • These crown plies, laid one on top of the other, overlap at an angle determined by the type of the tyre. www.cctyrespenrith.com.au

  11. Balance Wheel imbalance causes wheel tramp, or hop, makes the tyre vibrate up and down. Centrifugal forces try to throw heavy areas outward when the wheel is spinning. Weight must be evenly distributed around the axis of rotation. Imbalance can be rectified in one of two ways by Static Balancing (stationary) or Dynamic Balancing(spinning). www.cctyrespenrith.com.au

  12. Rotation A system of rotation is used to even out tyre wear and reduce the need for re-balancing. (a) (b) (a) 4-wheel bias (cross-ply) tyre rotation. (b) 5-wheel rotation (including spare). Radial tyres must be kept on the same side of the car. (c) 4-wheel radial tyre rotation. (c) (d) (d) 5-wheel radials (including spare). Care must be taken with spare as some modern tyres are directional. www.cctyrespenrith.com.au
