What Causes Many Small Pieces to Fall Off the Tire Tread?
2 Answers
Tire tread shedding many small pieces is caused by driving long distances with insufficient tire pressure. Below is additional information: 1. Function of tire tread: The tread prevents mechanical damage to the tire body, transmits vehicle traction and braking force, and cushions impacts endured during driving. It requires good wear resistance, puncture resistance, elasticity, and road grip performance. 2. Additional information: Tires are circular elastic rubber products mounted on various vehicles or machinery for ground rolling. In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government for "Improvements in the Wheels of Carriages and Other Vehicles." On December 10 of the same year, the first pneumatic tire was born.
I recently encountered this issue too, with many small chunks falling off the tire tread. I think it's mainly due to tire aging—my car is almost ten years old, and the rubber material becomes brittle, especially when the car isn't parked properly and is exposed to prolonged sunlight or low temperatures. Those small chunks peel off like tree bark. Another possible reason is abnormal tire pressure—too high or too low can cause uneven wear, and when going over speed bumps, the excessive vibration causes the chunks to fall off. I often remind my friends: check tire pressure regularly, avoid parking in hot spots during summer, replace tires early, and prioritize safety. If you notice a lot of chunks falling off, go to a repair shop immediately for inspection to avoid a high-speed blowout. Usually, just use a pressure gauge to check the tire pressure and keep it at the recommended value in the manual.
