How to tell if tires need replacement?
2 Answers
Here are methods to check if tires need replacement: 1. Regularly inspect the tire wear indicator bars on your vehicle. When the tread wear on the tire surface exceeds these replacement indicator bars, it indicates the tires must be replaced. 2. When there is uneven wear on the tire surface or edges, or when bulges appear on the tire sidewalls, the tires should be replaced promptly. Below is relevant information about tires: 1. Tire lifespan depends on many factors including driving habits, road conditions, vehicle load, inflation pressure, maintenance records, speed, and environmental conditions. Besides regular inspections and inflation pressure maintenance, it's recommended to conduct thorough inspections once tires have been in use for five years. 2. Tires generally consist of three parts: the outer tire, inner tube, and flap. The inner layer has an airtight rubber layer that gradually moves toward lightweight development. The outer tire mainly consists of the carcass, tread, sidewall, and bead.
After driving frequently, I've summarized a few simple methods to determine when tires need replacing. First, check the tread depth by inserting a one-yuan coin into the grooves. If the yellow edge of the coin is completely visible, it means the depth is less than 1.6mm and it's time for a change. Second, feel the tire surface for cracks or hardening, especially after winter when tires are prone to aging and cracking. Third, observe uneven wear patterns, such as excessive wear on one side, which may indicate suspension issues accelerating wear. Fourth, inspect for bulges or nail punctures, as these minor issues can lead to blowout risks. My routine is to check every six months or after driving 8,000 kilometers, while also measuring tire pressure and performing wheel alignment to prevent premature wear. This approach ensures peace of mind and safety. Generally, tires last 4-6 years before needing replacement—don't wait until a blowout causes an accident.
