How to Determine When to Replace Tires?
4 Answers
Methods to determine when to replace tires are: 1. Check the wear indicators. Tires have small raised platforms in the tread grooves or triangular symbols marked on both sides of the tire. Once the tread wears down to these indicators, the tire should be replaced or retreaded. 2. Examine tire uneven wear. If the center of the tire is severely worn while the sides are not, or if one side is significantly more worn than the other, the tire needs to be replaced as soon as any side reaches the wear indicator. 3. Inspect the tire sidewalls. If there are bulges or cracks on the sidewalls, it indicates that the tire cords may be broken or severely aged. To prevent blowouts while driving, it is recommended to replace the tire immediately. 4. Assess the degree of tire aging. If the tire shows signs of aging, such as numerous small cracks in the tread grooves or sidewalls that are close to damaging the tire body, replacement is necessary. Severely aged tires are prone to blowouts under high temperatures.
I usually rely on my tires for safety while driving. Last week, I noticed the steering wheel kept vibrating, so I immediately checked the tires and found the tread was as shallow as a worn-out floor. I promptly replaced them. Actually, judging when to replace tires is quite simple: First, check the tread depth by inserting a one-yuan coin into the tread. If you can see the entire top of the coin, the depth is insufficient, and it's time to replace them. Next, look at the production date—there's a four-digit code on the sidewall of the tire. The first two digits represent the week, and the last two represent the year. If it's been over six years, it's best to replace them. Also, check for bulges or cracks, and pay attention to excessive noise or pulling while driving, as these are warning signs. Old tires are prone to blowouts, so I inspect them myself before every seasonal change. Don’t skimp on safety—especially before long trips, always double-check.
Safety comes first, so I regularly check my tires to ensure safety on the road. There are three key points: if the tread depth is below 1.6mm, the friction decreases, making it easier to skid in the rain; aging time is also important—the sidewalls can become brittle and develop cracks, so even if the tread is deep, they should be replaced, with checks recommended around five years; don’t forget that tire pressure affects wear—too low can accelerate wear-out. It’s advisable to use a coin to measure tread depth monthly, and if you notice increased vibration or noise, visit a professional shop—don’t gamble with your life. When replacing tires, it’s recommended to replace all four at once to maintain balance and avoid damaging the chassis.
When to replace tires: Check these points: Is the tread severely worn? Insert a coin; if the coin head is visible, replace it. Are there any bulges or cracks? Is the ride too noisy or shaky? For old tires, check the production date mark; be cautious if over five years. Don't delay, safety comes first.
