Tire Safety Check: 3 Steps to Eliminate Hidden

Long-distance travel during holidays, frequent starts and stops, and complex road conditions place tires under far greater loads than usual, making them prone to hidden damage, abnormal wear, unstable tire pressure, and accelerated rubber aging.

Data shows that nearly 40% of highway accidents are related to tire failure. Bulges, blowouts, and reduced grip significantly increase braking distance and the risk of skidding and loss of control. Returning to high-frequency commutes after the holidays, a thorough tire check-up can eliminate potential safety hazards at the source, protecting your journeys.

Many car owners believe that as long as the tires aren't punctured or leaking, they can continue driving. However, this "wishful thinking" is easily overlooked. During long-distance driving, tires not only bear the weight of the vehicle and luggage but also cope with the impact of airflow at high speeds, gravel impacts, and uneven stress from steep slopes and sharp curves on mountain roads.

These can cause "hidden damage"—for example, the cords inside the tire sidewall may be quietly damaged, initially not showing as bulges, but the risk of a sudden blowout increases exponentially with the repeated pressure of high-frequency commutes after the holidays.

In addition, spring temperatures fluctuate greatly, with warmer days and significant temperature differences between day and night, causing tire pressure to fluctuate accordingly. If not adjusted in time, prolonged high or low pressure not only accelerates wear but also directly affects driving safety.

Don't worry, tire checks are not complicated. The following three-step guide requires no professional tools and can be easily completed by yourself.

01. Precisely Adjust Tire Pressure for a Solid Safety Foundation

Tire pressure is the "lifeline" of tires; both excessive and insufficient pressure can create hidden dangers. Excessive tire pressure reduces the contact area with the ground, leading to faster wear in the center and a higher risk of blowout when encountering bumps. Insufficient tire pressure increases sidewall pressure, increasing rolling resistance, which wastes fuel and increases the risk of skidding.

It is recommended to prepare a simple tire pressure gauge and measure the pressure after the vehicle has been stationary for at least 3 hours and the tires have completely cooled (this ensures accurate readings).

Then adjust the pressure according to the factory standard value marked on the B-pillar of the door or the inside of the fuel filler cap—note the difference between empty and fully loaded conditions; for daily commuting, adjust as if empty. Maintain consistent tire pressure across all four tires to prevent uneven wear or lane misalignment.

02. Carefully Inspect Wear to Identify Hidden Damage

First, clean the tires. Wipe away dirt and debris from the tread and sidewalls with a damp cloth for a clearer inspection.

First, check the surface: Focus on checking the sidewalls for bulges, scratches, punctures, or cracks. A bulge is the most dangerous sign, indicating broken internal cords, requiring immediate replacement. Small scratches that haven't damaged the cords can be observed later, but if the scratches are deep and expose the cords, replace the tire immediately.

Second, check the tread depth: Tread depth directly affects grip and water drainage. A simple way to check is to look at the tire wear indicators or insert a coin into the tread—if you can't see the numbers on the edge of the coin, the tread is almost worn down. The national standard is to replace the tire when the wear is less than 1.6 mm. If you frequently drive in rain or on mountain roads, it's recommended to consider replacing the tire when the wear is more than 3 mm.

3. Check for even wear: If you find severe wear on one side, faster wear in the middle, or a sawtooth pattern, it may indicate inaccurate tire pressure, wheel alignment misalignment, or a suspension problem. You should have it checked at a shop as soon as possible, otherwise even new tires won't last long.

03. Pay attention to aging; don't forget the spare tire.

Tires are made of rubber and will naturally age over time. Even if the tread is still deep, it may indicate a hidden risk. Generally, tires have a lifespan of about 5 years, depending on daily use and road conditions. If there are obvious small cracks on the tread or sidewall, and the cracks are deep and widespread, it is recommended to replace it even if it hasn't reached its lifespan.

Another easily overlooked area is the spare tire. Many car owners neglect it until they have a flat tire or break down and discover it's even worn out. After the holidays, check the spare tire's pressure, tread, and sidewall condition, and make sure the jack, wrench, and warning triangle are all there. This way, you can handle any situation on the road with ease.

In addition, here are some practical tips for post-holiday tire maintenance: If you drove over potholes or sharp objects during the holiday, pay special attention to checking for any hidden damage inside the tires. You can have them inspected at a professional repair shop.

During your daily commute, try to avoid sharp stones and potholes to reduce tire wear. Regularly rotate your tires (it's recommended to rotate them every 10,000 kilometers) to ensure even wear on all four tires and extend their lifespan.

Safety on the road is paramount. As the only part of the vehicle in contact with the ground, the condition of tires directly affects the safety of drivers and passengers. Timely tire checks after the holiday, and avoiding complacency, will ensure a worry-free commute.
