Tyres fitted for a commercial vehicle are different from a passenger vehicle not only by sizes and air pressures. A commercial tyre is engineered to carry heavier loads and travel on harsh road. With wide shoulder blocks to increase tread stiffness, allowing for all-weather handling and stability. It also comes with wide and narrow shoulder lug grooves, which enhance noise reduction and a solid center rib that handles traction control especially in high speed conditions. Unlike passenger tyre, a commercial tyre is designed for maximum inflation and have a load range of 10 ply, whereas passenger tyre only have a 4 ply load range.
