How Often Should Household Car Tires Be Replaced?
1 Answers
Generally affected by tire aging, it is recommended to replace tires every 3-5 years or every 30,000-50,000 kilometers. Due to varying usage environments, tire replacement should primarily consider wear, followed by age. If the wear is severe, even if used for only one year, replacement is necessary. Conversely, tires with minimal wear but in service for over 5 years must also be replaced to avoid the risk of blowouts. Methods to determine if tires need replacement are as follows: 1. Tread wear approaches the wear indicator: Any brand of tire has a wear indicator at the bottom of the tread grooves. For passenger car tires, the wear indicator height is typically 1.6 millimeters (this is also the legally mandated minimum groove depth), while for load-bearing tires, it is 2.4 millimeters. 2. Tires exhibit damage such as cracks or bulges: During daily use, tires may be punctured by foreign objects or accidentally hit curbs, leading to damage. Damages include tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and multiple punctures. Bulges, in particular, pose an immediate risk of bursting. Upon noticing such damage, owners should promptly visit a professional tire shop for inspection and replacement. 3. Tire age limit reached: Tires typically have a service life of about 5 years. Beyond this period, they begin to age, primarily evidenced by surface hardening and the appearance of cracks. Aged tires lose their elasticity, and continued use may lead to tread deformation and increased blowout risk.
