How to Determine Whether Tires Need Replacement

Methods to determine whether tires need replacement: 1. Check the tread depth, which is a crucial indicator for assessing tire replacement necessity; 2. Examine the degree of tire aging. The rubber material of tires has a shelf life of three years. Beyond this period, numerous small cracks will appear on the tire sidewalls - more cracks indicate more severe aging, in which case replacement is recommended. Automotive tires are one of the vehicle's critical components, directly contacting the road surface and working with the suspension system to absorb shocks during driving. They ensure good ride comfort and smooth operation, maintain excellent traction between wheels and road surface, enhance the vehicle's traction, braking, and off-road capability, while bearing the vehicle's weight.
As a DIY car enthusiast, the key to deciding whether to replace tires lies in checking tread depth and signs of aging. Insert a one-yuan coin into the tire tread—if the coin's edge is visible, it means the tread depth is below 1.6mm and replacement is mandatory. Also, check the wear indicators; if they're flush with the tread, the tire's lifespan is nearly over. Additionally, sidewall cracks or bulges signal aging, especially as summer heat accelerates deterioration. I recommend self-inspections every six months: before driving, check for uneven wear, which may indicate suspension issues. Tires typically last 4-6 years—don't exceed this. Opt for reputable brands and replace all four tires simultaneously to ensure handling stability and safe driving. Don't wait for an accident to regret neglect; regular checks proactively mitigate risks.
As a mom who regularly shuttles kids around, I pay close attention to tire safety. Here's a simple checklist: First, tread depth shouldn't be too shallow - use a tread depth gauge or your finger to check; if you can easily feel the wear indicators, it's time for replacement. Second, aged tires often develop fine cracks on the sidewalls, which become more noticeable over time. Additionally, if you notice increased slipping or noise while driving, it indicates deteriorating tire performance. I make time monthly to walk around my car for inspection, especially before and after rainy seasons when wet roads pose higher risks. Don't cut corners when replacing tires - I recommend professional inspection at authorized repair shops to ensure proper inflation after installation. Safety comes first - this investment is worthwhile, especially when transporting precious little ones.
