How To Fix Your Car’s Cracked Tires?

To fix your car’s cracked tires, you need to identify the causes of cracked tires, gather necessary tools, allow tires to cool down, examine the level of damage, apply sealant for internal cracks, apply degreaser, wipe and rinse the tires, apply tire protectant for external cracks, re-inflate, and re-install tires.

1. Identify the Causes of Cracked Tires

Tires can crack for a number of causes, such as UV radiation exposure, dry rot, poor construction, and inadequate upkeep. The rubber in tires can deteriorate and become brittle from exposure to UV rays from the sun, which can eventually shatter them. The rubber in the tire cracks as a result of dry rotting, which happens when the rubber dries out and loses its suppleness.

Cracking may also be caused by the low quality of the materials used to make tires. Last but not least, neglectful upkeep can result in tire cracking, such as incorrect tire inflation.

To receive access to the interior of the tire, start by removing the valve core using a valve core removal tool. The sealant should then be injected into the tire using the sealant injector that has been attached to the valve stem.

Replace the valve core and re-inflate the tire to the prescribed air pressure once the proper quantity of sealant has been injected. It’s critical to adhere to the sealant’s prescribed cure period.

5. Apply Degreaser

Make sure the tire is entirely dry before using the degreaser. Spray the tire with the degreaser, then scrub the surface with a stiff-bristled brush.
