Handling: Low tire pressure reduces the tire’s ability to maintain contact with the road. This leads to less stability during turns. As a result, a racer may find it harder to control the bike, particularly at high speeds. A study by Bell et al. (2020) found that optimal tire pressure enhances grip, thereby improving overall bike maneuverability.
Rolling resistance: Under-inflated tires have a higher rolling resistance. This means more energy is required to maintain speed. According to research from the Journal of Transport, rolling resistance can increase by up to 20% with lower tire pressure (Smith, 2019). Thus, athletes may expend more energy without gaining speed.
Tire wear: Low pressure can cause uneven tire wear. When tires do not maintain sufficient pressure, they can flex excessively. This leads to faster degradation of the rubber. Research shows that tires operated below recommended pressure can wear out 30% quicker than properly inflated tires (Jones, 2021).
Speed: Low tire pressure negatively affects a racer’s speed. As rolling resistance increases and handling worsens, racers may find it difficult to reach their peak speeds. According to a study published by the International Journal of Sports Science, racers reported an average speed drop of 2-4% with under-inflated tires (Taylor, 2018).
In summary, low tire pressure detrimentally affects race performance by impairing handling, increasing energy expenditure, causing faster tire degradation, and reducing speed.
What Are the Consequences of Overinflated Tires in Gravel Races?
Overinflated tires can severely affect performance and safety in gravel races. The consequences include reduced traction, increased risk of tire damage, and a harsh ride experience.
