Radial tires are a type of tire design where the internal cords are arranged at a 90-degree angle to the direction of travel. This construction allows for better flexibility and improved contact with the road, enhancing grip and stability. Radial tires are commonly used in vehicles like cars and trucks due to their durability and performance. One of the key benefits of radial tires is their ability to reduce rolling resistance, which can lead to better fuel efficiency. They also tend to wear more evenly compared to other tire types, such as bias-ply tires, making them a popular choice for everyday driving.
