Is Tire Repair Fluid Useful?
2 Answers
It can only be used for emergency purposes because the tire repair fluid can damage the tire. Here is some information about automotive tire repair fluid: Hazards: Tire repair fluid is a synthetic polymer compound that can cause chemical reactions with the inner rubber of the tire and the wheel hub, thereby corroding both the tire and the wheel hub. Additionally, tire repair fluid can affect the vehicle's driving stability. Under normal circumstances, tires need to maintain an even distribution of mass for proper operation. However, when tire repair fluid is injected into the tire, it may only adhere to one side of the tire wall, disrupting the tire's balance. Reasons for Not Using: Large leaks cannot be repaired: In theory, tire repair fluid can only fill small air leaks with a diameter of no more than 5mm. It is not effective for repairing cracks, and extensive damage cannot be fixed either. Sidewall punctures cannot be repaired: Tire repair fluid can only be used for punctures on the tread. Due to centrifugal force during injection and driving, the fluid can only fill the tread and cannot spread evenly on the sidewall. Therefore, punctures on the sidewall cannot be repaired.
Tire sealant can indeed be a lifesaver in emergencies. Half a year ago, it got me out of trouble on the highway. That day, my right rear tire was punctured by a nail and started leaking air with a hissing sound that made me panic. I pulled out the bottle of tire sealant that came with the car, followed the instructions to pour it into the valve stem, and managed to drive shakily for 20 kilometers to reach a repair shop. However, the mechanic told me this stuff is only suitable for small punctures. After use, the inside of the tire gets coated with a glue-like substance, which can damage the wheel rim over time. Most importantly, it's only a temporary fix to get you to a repair shop—speeds over 80 km/h can easily cause the tire to leak again.
