How to Check Tire Wear Condition?

[ColtonFitz]

Tire wear condition can be checked easily by examining the wear indicators in the tread grooves. Direct observation reveals the extent of tire wear. When the wear reaches the upper limit, various tire performances such as grip and braking distance will deteriorate. Relevant information about tires is as follows: 1. When purchasing tires, always check the production date: Do not buy tires with production dates that are too old. Tires are rubber products and will age even if unused. 2. During regular use, frequently inspect tire pressure and surface for damages: The tire sidewall is relatively fragile. If the sidewall is cut or punctured, it cannot be repaired. It is recommended to replace tires every four years, even if the mileage during that period is low.

Every time I wash my car, I squat down to carefully inspect the tire treads. There's a raised wear indicator bar in the middle of the tire – when the tread wears down to be level with this indicator, it's time to replace the tire. I also use the one-yuan coin test: insert the coin vertically into the tire groove; if the national emblem on the coin is fully visible, it indicates severe wear. Don't just look at the front side – uneven wear on the inner and outer sides of the tire is even more critical, signaling the need for wheel alignment. My neighbor once had a terrifying tire blowout on the highway because he didn't notice the inner side had worn flat. Remember, regularly checking the tire's age is also crucial, as rubber hardens and cracks after five years.

Last week, I accompanied a friend to the repair shop and learned a professional inspection technique. They used a tread depth gauge to measure the groove depth, recommending tire replacement if it was below 1.6mm. Actually, we can make a preliminary check ourselves using a coin: take a one-yuan coin, insert it into the groove with the national emblem facing down, and if the top of the emblem is visible, it's time to be cautious. The key is to inspect the entire circumference, as edge wear is often more dangerous than center wear. The mechanic mentioned that 90% of blowouts are caused by sidewall bulges or cracks, so running your hand around the tire to feel for bumps or cracks is especially important. Insufficient tire pressure leads to excessive shoulder wear, something many people overlook.

I have an OCD-like habit of checking my tires monthly. First, I examine the tread under sunlight - if the reflective area appears wider, it's a sign of wear. Running my thumb along the grooves helps detect unevenness. The worst is seeing sawtooth wear patterns, indicating suspension issues. Last time I noticed front tires wearing faster than rears, realizing I'd forgotten regular rotation. Here's a simple trick: periodically rub your foot against the tire - if it feels smooth like a bald head, trouble's brewing. Aged tires develop spiderweb cracks on sidewalls, especially for outdoor-parked cars. Pre-road trip tire checks have become my mandatory ritual.
