The pursuit of optimal bike performance and efficiency often prioritizes aerodynamics, gearing, and rider position, yet one crucial aspect is frequently overlooked: the relationship between tire pressure, rolling resistance, and road surface. Whats the most effective method for determining the ideal tire pressure to balance rolling resistance and traction on varying road surfaces, considering the often-disregarded impact of temperature fluctuations and load distribution on tire performance? How do manufacturers recommended pressures account for real-world conditions, and what data-driven approaches can riders use to optimize their tire setup for long-distance, mixed-surface routes like the TransAmerica Trail?
