A tire gel balancing composition having a Storage modulus of between 3000 and 15000 Pa and the Specific Gravity less than 1000 kg/m3 in the temperature range between -20 DEG and +90 DEG 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, including castor oil, or polyol ethers; 2) hydrophobic or hydrophilic fumed silica; 3) polyalkyl-methacrylates, styrene-ethylene-propylene block copolymers or polyhydroxycarboxylic acid derivatives; and optionally corrosion inhibitors and antioxidants.
