Even though on the outside OTR tires look like they are entirely made of rubber, different components come together to make them more functional.
OTR tire construction usually comes in two major categories - Radial and Bias construction.
The major differences between these two types of constructions is normally the arrangement of the ply found in the inside of the carcass and the sidewall of the tire.
Let's take a look at them more extensively;
Radial OTR Tire Construction
Radial tires usually have numerous steel cords arranged at an angle of 90 degrees to the center of the tire. The cords are laid down from one bead to the next covering the entire length of the tire. They are chords are accompanied by belts beneath the treads to boost the stability of the tire.
Advantages of OTR Tires With Radial Construction
Stability: Their construction gives the sidewalls the ability to stretch on uneven grounds thereby covering more surface area to enhance stability.
Less Costly: They have a very low rolling resistance which gives them the ability to consume less fuel thus saving on costs.
Longer life: No friction is generated between the layers thanks to the radial arrangement which means no damaging heat build-up during operations. This makes the tires last longer.
Operator Comfort: Since they are more flexible they can absorb most of the shock during bumpy rides which is key for operator comfort.
Disadvantages: Their side walls can be damaged easily.
Bias OTR Tire Construction
In this case the cords are laid down in several layers that cross each other at angles of 35 degrees as they stretch from bead to bead. The cords that form the plies are usually made out of nylon. Thanks to the crossing of the plys these tires usually have a firm sidewall that is not easily damaged.
Advantages OTR tires with Bias Construction
Strength: Since these tires have a stronger structure they can handle more load with minimal destruction.
Damage Resistant: The plies that are arranged at angles make their sidewall tough and therefore resistant to damage.
Stability: Their structure also makes them more stable especially on very uneven surfaces since their construction allows the tire treads more movement.
Disadvantages: They are less stable in higher speeds and consume more fuel due to lower rolling resistance.
