Unfortunately, flat tires are sometimes unavoidable. Nails and screws, glass, potholes, and other road hazards can puncture your tires without warning. Sometimes the result is a slow leak - usually if an object gets lodged in the tire - others result in a near immediate flat. The good news is, many punctures can be repaired at a much lower cost than it would be to replace the tire.
Here are four guidelines to follow when deciding if a tire can and should be patched. Your local Pep Boys expert will be able to tell you whether your tire meets the criteria:
- Damage should be less than 1/4" in diameter.
- Punctures should not be on the tire’s shoulder or in the sidewall.
- Tire should be removed from the wheel and inspected for interior damage. If the interior damage is extensive, the tire should not be repaired.
- Repair the tire not long after it is punctured. Even driving on slow leaks can allow moisture into the tire, which can cause damage to steel cords and belts.
Repairs should completely fill the path taken by the object through the tire. Patches on the inside will reseal the inner-liner, but if the path remains open, it may allow potentially damaging moisture inside.
