This invention relates to vulcanizable diene rubber compounds with a high capacity for the addition of sulfur to be varied while processing safety is maintained, for the production of improved rubber moldings, particularly tire components. The stabilizer housing can be easily opened and re-closed securely by the user, who can remove, replace, and change the contents, which includes extra elastomer modules of varying weight to get the exact desired weight, side-to-side andor front-to-back balance, andor vibration and sound dampening effect. The non-aqueous electrolytic solution containing at least an organic solvent and a lithium salt further contains a particular pyridine compound.
