Tire lubricant is an essential ingredient when working with car tires and rims. To remove an old tire, you must soften the rubber with heat and lubricate the rim, even if the tire is worn. New tires are much stiffer and therefore require a lot more heat and lubrication. If you look on YouTube you will see various lubrication recommendations including soapy water, Windex and even WD40. BeadBuster tire mounting paste outperforms all other options. It is a strong petroleum jelly gel, similar in consistency to petroleum jelly, that provides long-lasting and effective lubrication. This makes changing tires easier. You can probably use it for other reasons too, like making things slippery.
