Should I Replace Tires with Cracks?
2 Answers
Tire surface cracks are recommended to be replaced promptly. Theoretically, regardless of the severity or visibility of the cracks, timely replacement is advised. However, in practice, flexible analysis based on actual conditions is also acceptable. Replacement based on wear condition: Tire grooves are equipped with wear limit indicators. When the wear reaches these indicators, exposing them externally, the tires should be replaced. The limit is approximately 1.6mm, and generally, it is recommended to replace tires when the groove depth falls below 2.5mm. Replacement based on service life: Some car owners drive very little after purchasing their vehicles. Generally, affected by tire aging, it is recommended to replace tires every 6 years. Since the driving environment varies for each vehicle, the decision to replace should consider actual conditions. If the wear is severe, replacement is necessary even after just one year of use. If the wear is not severe, tires must still be replaced after 6 years to avoid the risk of blowouts.
As someone who frequently drives long distances, I believe tire cracks should never be taken lightly. What may seem like a minor issue is actually a sign of tire aging, which over time can lead to slow leaks or sudden blowouts—especially dangerous at high speeds. My experience tells me that cracks often appear on the sidewalls or in the tread grooves, and if they exceed 1-2 mm in depth, the tire should be replaced immediately. Tires typically age after 3-5 years of use, so I recommend regularly checking tire pressure and surface condition, and avoiding prolonged parking under direct sunlight. Safety comes first—don’t risk major accidents to save a little money. Replacing a tire isn’t too costly, but it brings much greater peace of mind. Developing a habit of monthly visual inspections is a smart way to prevent problems before they arise.
