Types of Tyres
To make your travel more enjoyable tyres are categorised by vehicle type, structure, season, pattern and various other special uses.
Bias Tyre
Bias tyres are used primarily for off-the-road, agricultural, and industrial vehicles.
Structure of a bias tyre
The carcass of a bias tyre has cords that alternate with one ply each in a crisscross angle formation. Thus, the angle of the alternating cords against the road surface is approximately 40 degrees on the circumference. Both carcass and belts are made out of nylon.
Change in tyre tread while driving
Tread movement is sensitive to shifting weight and the number of revolutions as treads wear down quicker at high levels of heat. However, because the tread is fully capable of supporting weight, bias tyres are appropriate for driving on unpaved roads and large vehicles. Their biggest advantage is flexibility and good drivability.
Radial Tyre
Radial tyres are produced for passenger cars, light trucks and buses.
Structure of a radial tyre
The radial tyre refers to a tyre in which the cords are arranged perpendicular to its circumference. Due to this cord arrangement, the radial tyre has a lower flatness ratio than the bias tyre. Also due to its high horizontal resistance, the radial tyre has superior starting, acceleration, controllability, rotationally and safety characteristics and which is are best suited for high-speed travel. Both the carcass and belts are made out of steel.
Change in tyre tread while driving
Despite changes in radial tyre tread while driving, you will notice no change in the contact area between tread and road surface. The radial tyre is often used for passenger cars. Its advantages are high tread resistance and resistance to slipping while cornering due to low rolling resistance while driving.
