Radial tires are considered superior due to their unique construction, which features a flexible sidewall that enhances performance. This design allows for greater movement in the bead area, leading to improved handling and stability. However, the increased flexibility also results in higher stress transfer to the rim, with radial tires exerting over 75% more stress on the rim base compared to bias tires. This can lead to potential failures in rim back sections and flanges under higher operating pressures. Overall, the scientific rationale behind the preference for radial tires lies in their balance of performance benefits and the challenges they pose to rim durability.
