Tire repair FAQs
Can a tire with a nail in it be repaired?
A nail puncture may be repairable if it is within the repairable tread area, no larger than 1/4 inch, and the tire has no disqualifying damage. The tire must be removed from the wheel for an internal inspection. Manufacturer restrictions, previous repairs, and damage from driving underinflated can rule out repair.
Can you patch a tire sidewall or a bulge?
No. A sidewall puncture or bulge is not a candidate for a standard puncture repair. A bulge can indicate internal structural damage, even if the tire still holds air. Arrange a safe replacement rather than continuing to drive on it; the correct replacement tire must match your vehicle’s requirements.
Is an outside tire plug a permanent repair?
A plug inserted from outside the tire is not an acceptable permanent repair under industry guidance. A proper repair requires an internal inspection, filling the puncture channel, and sealing the inner liner. A plug alone can leave hidden damage or an inadequately sealed tire unaddressed.
Why does one tire keep losing air when I cannot see a puncture?
A slow leak can come from the valve stem, valve core, wheel, or the seal between the tire and wheel. Small tread punctures may also be hard to spot. If one tire repeatedly loses pressure faster than the others, have the tire and wheel assembly checked instead of repeatedly topping it up.
