emergency tire puncture repair kit.
A puncture caused by a nail or screw passing through the tire tread can be repaired temporarily with the emergency tire puncture repair kit. (The kit containsa bottle of sealant. The sealant can be used only once to temporarily repair one tire
without removing the nail or screw from the tire.)
After temporarily repairing the tire with the kit, have the tire repaired or replaced

Driving even a short distance with a flat tire can damage the tire and the wheel beyond
repair.

the tire may explode when using the emergency tire puncture repair kit, resulting in death or serious injury.INFORMATION
