Several factors can impact the longevity and performance of timing belt rubber. One of the most significant factors is temperature. Timing belts operate in an environment that can vary from extremely high to low temperatures. Excessive heat can lead to the degradation of rubber materials, while cold temperatures can make the rubber brittle and less flexible. Therefore, choosing a timing belt made from high-quality rubber is essential to withstand such extremes.

While timing chains are more durable, they do have their drawbacks. They tend to be heavier, which can increase the overall weight of the engine. Additionally, timing chains can be noisier than belts, leading to some engine noise which may be undesirable for certain drivers. They also require regular maintenance, as they need to be properly lubricated, and if they become loose over time, they can affect engine performance and lead to premature wear.
