radial tire

A radial tire is a type of pneumatic tire where the ply cords, which run from the bead to the tread, are laid at approximately 90 degrees to the centerline of the tread. This construction, also known as radial-ply tire, is now standard for most automobiles. Radial tires offer advantages such as better steering, less rolling resistance, and longer mileage compared to bias-ply tires. They tend to run cooler and are considered safer in adverse weather conditions, though they can be more expensive and provide a slightly harder ride.12
