"Based on the perceived and real performance advantages of the radial casing constructions in Schwalbe's mountain bike tires, we predicted that it was only a matter of time before more brands got on board with this technology. While we've seen a similar design from the small brand Zleen, it turns out, somewhat surprisingly, that Vee Tire Co. is the first larger tire brand to officially roll out radial casings on its tires. Vee's new RAD-Core tires were unveiled just recently at iceBike."
"Traditional mountain bike tire casings use criss-crossing threads arranged diagonally, typically at 45 degrees to the direction of travel. Tires with a radial construction, like those on a car, have the casing threads arranged "radially," or at 90 degrees, perpendicular (or close to it) to the direction of travel. This orientation allows the tire to be more supple and deform to the trail surface more locally, creating a larger contact patch and improving traction."
Radial tire construction orients casing threads at or near 90 degrees to the direction of travel, producing a more supple casing that deforms locally to the trail and increases the contact patch for improved traction. The increased suppleness permits higher tire pressures, which lowers rolling resistance and reduces the risk of pinch flats while maintaining or improving grip. Schwalbe previously introduced a near-radial casing (about 10–20 degrees from 90) and saw strong performance results. Vee Tire Co. introduced a true 90-degree RAD-Core radial casing and unveiled the new tires at iceBike, marking broader adoption of the technology.
