Can a Tire with Tire Sealant Still Be Repaired?
1 Answers
It is still possible to repair the tire. Tire sealant is a mixture containing various high-molecular chemical materials. It is widely suitable for rubber tires on electric vehicles, motorcycles, and small to medium-sized cars, and is particularly effective for punctures with diameters of about 1–5 mm. It is an essential item to carry in the vehicle. The working principle of tire sealant involves the fibers and rubber particles or suspended fine rubber particles in the sealant. When the tire loses air, these particles aggregate and block the puncture hole. Since it works by blocking, it is highly effective for small holes, especially in tubeless tires, but less effective for larger cuts. Side effects of tire sealant: After using one can of sealant, approximately 200ml–300ml of residual liquid remains inside the tire, similar in volume to a standard soda can. This will inevitably affect the wheel's dynamic balance, so extra caution is required while driving. The sealant can also damage the wheel rim because the liquid corrodes it, leading to reduced sealing performance when the tire is removed next time. Precautions for tire repair: After repairing the tire and reinstalling it, inflate both sides of the tire quickly to seal it. Then, install the valve core and inflate to the recommended pressure before tightening the valve core. Finally, check for leaks before use. If the tire sidewall has a hole larger than a thumbnail or the tread is severely punctured by objects like rebar, it is safer to replace the tire entirely. Such significant damage is difficult to repair effectively, and the results may not be reliable.
