ABSTRACT:
A tire gel balancing composition having a Storage modulus of between 3000 and 15000 Pa and the Specific Gravity less than 1000 kg/m.sup.3 in the temperature range between -20.degree. and +90.degree. C., preferably its Storage modulus is about 9000 Pa, is capable of balancing tires by being able to flow under the vibrations caused by imbalance in a wheel assembly. The composition preferably comprises a mixture of: 1) paraffinic oils, polybutene oils, polyol esters or polyol ethers; 2) hydrophobic or hydrophilic fumed silica; 3) poly-alkyl-methacrylates, styrene-ethylene-propylene block copolymers or polyhydroxycarboxyl acid derivatives; and optionally corrosion inhibitors and antioxidants.
