How Long Can You Drive with Worn Tire Treads?

[RachelLee]

Tires should not be driven when they are worn flat. Worn tire treads can lead to reduced grip and increased risk of skidding. At this point, the tires must be replaced as they no longer provide safe driving conditions. According to national standards, the wear limit for tread depth on passenger car radial tires is 1.6mm. When the tire tread wears down to this level, both the tire's water drainage capability and grip are significantly reduced. Additional information: 1. Hazards of worn tires: As the tread becomes shallower, water drainage is hindered, friction decreases, and the risk of skidding or rollover during normal driving or braking increases, potentially causing loss of vehicle control; braking distance lengthens; tires become more susceptible to punctures and blowouts. 2. Tire lifespan: The recommended lifespan for tires is 5 years or 80,000 kilometers. If either the time or mileage limit is reached, it is advisable to replace the tires. Tires older than this recommended lifespan begin to degrade and may deform or blow out if continued to be used.
