Can tires with cracks in the middle grooves continue to be used?

Rubber products have a service life, and tires with cracks cannot continue to be used. Below are specific details about tires: 1. Functions of tires: Tires support the entire weight of the vehicle, bear the load of the car, transmit traction and braking torque, ensure the adhesion between the wheels and the road, reduce and absorb vibrations and impacts during driving, prevent severe vibrations and early damage to vehicle components, adapt to the high-speed performance of the vehicle, reduce noise during driving, and ensure driving safety, handling stability, comfort, and fuel economy. 2. Tire maintenance methods: Tire maintenance methods include regularly cleaning stones from tire grooves, reducing exposure to sunlight, frequently checking tire pressure, paying attention to suspension maintenance, periodically inspecting front wheel alignment, and being mindful of driving habits. 3. Replacement period: The service life of tires is about 5 years, with the specific duration related to driving habits, temperature, and environment. Generally, after 5 to 6 years of use, tires will age and develop cracks, increasing the risk of blowouts. If the tire tread is worn flat, traction will decrease, making the vehicle more prone to skidding. These factors can endanger driving safety, necessitating tire replacement.
As a seasoned long-distance driver, I fully understand the potential risks of cracked tire grooves. Those small cracks in the central tread may seem minor, but they can gradually worsen into serious hazards. Rubber materials degrade over time, with UV exposure, high temperatures, and driving wear accelerating this process. Once the cracks deepen and reach the internal steel belt layer, the tire could suddenly blow out at high speeds. This is especially dangerous on wet roads, where reduced grip increases the risk of skidding. I once encountered a similar situation—upon inspection, small cracks had widened significantly, so I promptly replaced the tires, avoiding towing fees and potential accidents. Safety should always come first; don’t gamble with risks. Get a professional evaluation immediately.
I've always been the car maintenance expert in my family, and dealing with tire cracks depends on the specific situation. If the groove cracks are shallow and superficial without damaging the internal structure, you can still use them temporarily but need to frequently check for changes in the cracks. However, if the cracks are noticeably wide or located at stress points, they must be replaced immediately; otherwise, you risk losing control when turning in rainy conditions. Tire aging is the main culprit, with tires over five years old or those parked outdoors for extended periods being more prone to issues. I recommend checking tire pressure and cracks every two weeks, and if in doubt, spend a little money to have them tested at a shop. Preventive measures with small costs are always better than spending big on repairs later—driving safety is no trivial matter.
Tire groove cracks typically originate from rubber aging, becoming brittle when exposed to daily use, sunlight, and extreme weather conditions. Superficial cracks may be temporarily safe if not deep, but if they extend to the underlying layers, they can compromise the tire's structural integrity, leading to air leaks or blowouts. During vehicle maintenance, I've encountered similar cases: when cracks are located near the central grooves, accumulated water can accelerate damage. It's advisable to inspect tires quarterly. If cracks are found, test their depth with a fingernail—if exceeding 2mm, immediate attention is required. Timely replacement can prevent subsequent issues.
