Only Air Escaping
This is a indication that there is an insufficient amount of Ultraseal in the tire, or the tire may have internal damage. Re-enter the wound with a pointed object (ice pick) and move it back and forth. As it is extracted, Ultraseal will be forced out through the wound. If no Ultraseal is visible, there is not enough sealant in the tire to provide a coating and seal the puncture. Either and insufficient amount of Ultraseal was initially installed or the tire has received numerous punctures or a dangerous puncture that has depleted the Ultraseal in the tire.

Air and Ultraseal Bleeding
Air and Ultraseal will bleed out of a wound, only if the wound is too large or the puncturing object has significantly damaged the tire’s inner structure. This is a potentially dangerous tire. Dismount the tire and inspect it, do not plug or repair by any external method! The bleeding effect is an important proprietary function of Ultraseal, providing an additional margin of safety.

Air Loss Due to a Slow Leak
In rare circumstances, where air has been continuously slow-leaking from areas that are difficult for Ultraseal to rapidly reach, such as a bead leak, it may take more than 3 to 5 miles of driving for Ultraseal to eliminate the problem air leaks. If air migration persists, increase air pressure 10% to 15% (do not exceed maximum allowable tire pressure as recommended by the tire manufacturer) and drive vehicle approximately two days, then reduce air pressure to normal setting. By increasing air pressure, it opens the pores and forces Ultraseal into the problem area, eliminating air migration.

Sidewall Puncture
Ultraseal is designed to provide puncture protection for the tread area of the tire only. The tread area has sufficient rubber and plies for adequate flexing and recovery, but sidewall construction is extremely thin, especially in radial tires, and will not safely hold a repair. Ultraseal does not guarantee to seal punctures in the sidewall or shoulder of a tire.

Major Damage
If a tire treated with Ultraseal sustains major structural damage or a puncture larger than ¼” (½” with XHD formula), it cannot hold air pressure. Ultraseal is designed to slowly release air pressure, providing a margin of safety that is not found in any conventional tire. Regardless of how small or how large the wound may be, Ultraseal cannot mask or hide a dangerous wound. If the wound is severe, Ultraseal and air will slowly bleed. This safety feature assists the driver in coming to a safe and controlled stop.

Valve Core Blockage
If air will not go into the tire, check the valve core, it may be clogged. This can occasionally occur if air pressure was checked without first clearing the Ultraseal from the valve stem, or if there is a defective valve core. If the core appears to be in good condition, then simply rinse it with water and reinstall. In rare cases, it may be necessary to replace a valve core.
