A tire sealant composition is provided for sealing punctures in pneumatic tires, particularly in the extreme outer shoulder edge and sidewall, comprising a liquid carrier, latex in an amount between about 0.5 to about 6.0% by weight of the composition, a polysaccharide suspending agent and a particulate material with a particle size of less than 300 μm. The composition allows for passage through the tire valve without the need for removal of the valve core.
