Types of Tires

To make your travel more enjoyable, tires are categorized by vehicle type, structure, season, and various other special uses.

To make your travel more enjoyable, tires are categorized by vehicle type, structure, season, and various other special uses.

Bias Tire

Bias tires are used primarily for off-the-road, agricultural, and industrial vehicles.

Structure of a bias tire

The carcass of a bias tire 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.

Deformation of tread during driving

Loads on tire or cornering while driving causes a deformation of tread, which makes heat-generation and uneven wear. However bias tires have demands on
Off-the-Road condition and Heavy vehicles.

 

Radial Tire

Radial tires are produced for passenger cars, light trucks, trucks, and buses.

Structure of a radial tire

The radial tire refers to a tire in which the cords are arranged perpendicular to its circumference. Due to this cord arrangement, the radial tire has a lower flatness ratio than the bias tire. Also due to its high horizontal resistance, the radial tire has superior starting, acceleration, controllability, rotationality and safety characteristics and is best suited for high-speed travel. Both carcass and belts are made out of steel.

Change in tire tread while driving

Despite changes in radial tire tread while driving, you will notice no change in the contact area between tread and road surface. The radial tire is often used for passenger cars. Its advantages are high rigidity of tread which makes cornering be stable and low rolling resistance.
