Should You Replace or Repair a Punctured Tire?
2 Answers
Tire punctures can be either repaired or require replacement depending on the severity of the damage. Small punctures can typically be fixed with a patch, while larger punctures or structural damage may necessitate a full tire replacement. There are three primary methods for repairing punctured tires: 1. Plug Repair: This method is convenient as it doesn't require removing the tire, but it involves enlarging the puncture hole, which can further damage the tire. 2. Patch Repair: The most commonly used method, though over time, the patch may allow water to seep in, potentially damaging the tire's internal structure. 3. Mushroom Plug Repair: Combining the benefits of both plug and patch repairs, this method is the most reliable but also the most expensive.
When a tire gets punctured, whether to replace or repair it depends on the location and size of the damage. If the nail only punctures a small spot in the center of the tread, patching is usually safe and cost-effective. With over 20 years of driving experience, I know a patch job costs just a few dozen yuan, but the tire must be removed first to check if the internal structure is intact. If the hole is too large or near the shoulder, it's better to replace the entire tire, as patching can lead to blowouts at high speeds, posing significant safety risks. Additionally, older tires or those with existing cracks carry higher risks when patched. Safety comes first—don't overlook potential accidents to save a small amount of money. Regular maintenance can also extend tire lifespan.
