In summary, rubber tire hardness results from a combination of environmental factors, degradation processes, and lack of use, all contributing to the overall decline in tire performance.
How Can You Identify if Your Rubber Tires Have Hardened?
You can identify if your rubber tires have hardened by checking for signs such as visual cracks, reduced traction, a loss of flexibility, and an increase in road noise.
Visual cracks: Examine the tire’s surface closely for small cracks or fissures. These cracks indicate aging and a loss of elasticity, which is a key sign of hardened rubber. As the tire ages, it becomes less pliable and develops surface defects.
Reduced traction: Conduct a simple traction test. When driving, pay attention to how your vehicle handles during turns and sudden stops. Hard rubber tires often lack grip and can cause the vehicle to slide in wet or slippery conditions. This reduction in grip increases the risk of accidents.
Loss of flexibility: Press your thumb against the tire sidewall. If it feels unusually stiff and does not give under pressure, the tire may have hardened. Healthy rubber should have some yield or flex when pressure is applied.
Increased road noise: Listen for changes in noise levels while driving. Hardened tires can produce a louder, more pronounced sound on the road. This occurs because hardened rubber cannot absorb impact as effectively as flexible rubber, leading to higher noise levels inside the vehicle.
According to a study by Huang et al. (2021) published in the Journal of Engineering, tires lose their performance characteristics as they harden, which can compromise vehicle safety. Regular inspection of tire condition will help ensure safer driving experiences.
