A study by the National Highway Traffic Safety Administration (NHTSA) in 2018 found that worn-out tires can increase the likelihood of hydroplaning by 30%.
-
Increased Stopping Distances: Increased stopping distances result from the reduced friction between hardened tires and the road surface. Vehicles equipped with hardened tires may require longer distances to halt effectively. According to the Tire Industry Association, a tire with insufficient tread depth can lead to stopping distances that exceed those of properly maintained tires by up to 40%.
-
Greater Risk of Blowouts: Greater risk of blowouts arises as tires harden and their internal structures weaken. The deterioration can lead to unexpected tire failures, especially under high speeds or heavy loads. The Rubber Manufacturers Association reported that blowouts often result in loss of vehicle control and are a contributing factor in 6% of all motor vehicle crashes.
-
Diminished Ride Comfort: Diminished ride comfort refers to the reduced ability of hardened tires to absorb road imperfections. This decline can lead to a harsher driving experience. Poorly maintained tires can transmit more vibrations into the vehicle, impacting passenger comfort. A report by Consumer Reports indicates that tire comfort can affect driving satisfaction, highlighting the importance of using tires in good condition.
How Can Vehicle Owners Keep Tires Flexible as They Age?
Vehicle owners can keep tires flexible as they age by regularly monitoring tire pressure, using tire dressings, rotating tires, and maintaining proper storage conditions.
Regular monitoring of tire pressure: A tire’s air pressure affects its flexibility. According to the National Highway Traffic Safety Administration (NHTSA), underinflated tires can become stiffer and more prone to cracking. Maintaining correct tire pressure helps keep the rubber supple and flexible. Check the pressure at least once a month.
Using tire dressings: Tire dressings contain oils and conditioners that help moisturize the rubber and protect it from drying out. A study by the Rubber Manufacturers Association (RMA) in 2021 indicated that regular application of tire dressing can extend the life of a tire by preventing hardening and cracking.
Rotating tires: Regularly rotating tires promotes even wear across all tires. This practice can be done every 5,000 to 8,000 miles, as recommended by tire manufacturers. An even distribution of wear helps maintain optimal flexibility in the rubber compound.
