When Does a Car Need to Replace Tires?

[ZaneLynn]

Car tires need to be replaced after 5 years of use. Car tires are one of the important components of a vehicle, directly contacting the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving, maintaining excellent adhesion between the wheels and the road surface, improving traction, braking, and off-road capability, and bearing the weight of the car. Methods to determine if tires need replacement: 1. Tire aging usually occurs on the tread patterns and sidewalls; if the tread patterns have reached the wear indicator or even gone below it; 2. If there is local bulging on the tire, continuing to drive may pose an explosion risk; 3. Assess the depth and area of tire damage to decide whether to repair or replace the tire directly; 4. If the sidewall is damaged, it usually requires direct replacement; 5. If the tire has been repaired too many times, its strength may no longer meet road safety requirements.

As a seasoned driver with over a decade of experience, I know that changing tires is not something to be taken lightly. Tread depth is crucial - insert a one-yuan coin into the groove, and if the national emblem pattern is still visible, it means the tread is too shallow and it's time for a change. Also, check for cracks and bulges, especially on the sidewalls of the tires. Even small defects like these can lead to a blowout at any moment. The age of the tires is important too; most tires can only last five or six years at most. Even if the tread depth is sufficient, aged rubber may not withstand the expansion and contraction from high-speed driving. I make it a habit to walk around my car every three months to check for uneven wear, preventing premature wear caused by misaligned wheels. When it comes to road safety, skimping on small expenses is not worth it. Spending a few hundred yuan on new tires is far more economical than dealing with an accident. Experience tells me that regular tire maintenance keeps the car running smoother and longer.

I just got my driver's license not long ago and had no idea when to replace tires when buying my first used car. Later, I felt the wheels skidding while overtaking on the highway during rain. At the repair shop, they found the tread depth was only 1.2mm, and the technician said anything below 1.6mm requires replacement. Now I use my phone to research and learn how to check tires: if the wear indicators are flush, it's dangerous, and also watch for small bubbles or scratches on the tire edges. On car owner forums, they suggest manually checking the tires every month and addressing any abnormalities promptly. New car tires can last 50,000-60,000 kilometers, but since used cars wear faster, I keep a closer eye on them. Replacing tires isn't cheap, but safety comes first—no compromises. Now I've made it a habit to glance at my tire condition before driving.

Having worked in the auto maintenance industry for a long time, I've seen too many tire failure cases. There are three main points to consider when replacing tires: first, tread depth - if measured with a special caliper and found to be below 1.6mm, replacement is mandatory; second, aging cracks - if the tire surface shows cracks due to prolonged sun exposure, it needs early attention; third, bulges or internal structural damage, all of which affect driving safety. The typical lifespan of a tire is five to six years, as older rubber tends to harden and crack easily. I recommend car owners check tire pressure and external wear every six months, and address any abnormalities promptly. Professional inspection doesn't take long but can prevent potential risks.
