3 reasons Alloy wheels are used
9
Main construction of radial and cross ply tyres
The casing consists of plies which are looped around the beads to form a case. The difference in structure is the arrangement of the plies.
10
3 advantages of a radial tyre
less rolling resistance giving better fuel economy
improved tread life
improved traction (grip).

Tyre tread
Symmetrical - deliver smooth driving, high directional stability, and low rolling resistance. Directional - provide high protection against aquaplaning, excellent handling on snow and mud, and very good road-holding at high speeds.
Asymmetric - offer excellent handling, high curve stability, and good grip in wet conditions.
14
Tyre tread pattern design
Tread compound: grip, wear rate, flexibility, rolling resistance, etc.
Circumferential grooves: steerability and water dispersal
Cross ribs (lateral notches): traction and mud evacuation
Blocks: provide high mileage performance and good grip
