Radial OTR tires are gaining market share due to their superior performance, lower total cost of ownership, and improved traction. Radial technology is increasingly preferred for its fuel efficiency and longer lifespan in construction, earthmoving, and agricultural roles. While bias tires remain strong in specialized sectors like mining and waste (due to high impact resistance), radials are gaining because of their superior ROI. The initial higher cost of radials is usually offset by lower fuel consumption and increased tire life.
