Why is there a slight air leak after tire repair?
2 Answers
Tire repair may result in a slight air leak if the repair is not properly sealed. It is essential to remove the tire immediately for a thorough inspection and re-repair. Driving even a short distance on an underinflated tire can cause damage that may render the tire irreparable. Precautions for tire repair: Repairs should not be performed immediately after stopping the vehicle. The heat generated from friction has not yet dissipated, and the wheel may be deformed. Repairing at this time can cause damage to the wheel. Before repair, check the wheel surface for cracks. If cracks are present, they must be addressed first. Otherwise, attempting a repair without treating the cracks may not only fail to solve the issue but could also cause further damage to the wheel. You can run your fingers over the wheel surface to check for roughness—smoothness indicates no cracks, while roughness warrants further inspection to locate the cracks. Note on wheel cleaning: The cleaning agent used for wheels should be pure, preferably a neutral cleaner. Acidic or alkaline cleaners can corrode the wheel, affecting its structure and physical properties, ultimately compromising the vehicle's safety and driving performance.
Bro, I've been driving for over 20 years and seen this happen a lot. If a tire still leaks after being patched, it's usually because the patch didn't stick properly or the area wasn't cleaned well during the repair. Dust or moisture can get in, preventing the adhesive from bonding firmly, and air seeps out through the gaps. Sometimes, the tire itself has tiny cracks that make patching ineffective, and you'll need a new tire. It could also be that the wheel rim edge is uneven or rusty and needs smoothing out. Even a slow leak is dangerous—it can lead to a blowout or sudden loss of control. I suggest getting it checked at a shop right away instead of trying to fix it yourself. Safety first! And don't forget to check your tire pressure regularly—good habits can prevent a lot of trouble.
