Dry rot can adversely effect the heath and lifespan of automobile tires. Dry rot generally occurs when tires get brittle and dry due to low air pressure, inactivity, exposure to ultraviolet and ozone rays and the grime accumulation that breaks down its rubber layers. Special tire protection care is essential to preventing dry rot. If it is not caught early, dry rot can completely damage tires and cause them to be unsafe on the road.
Inspect the damage. Examine where tires have become especially worn and where tire walls have become cracked. The longer the tires have been sitting stagnant and exposed to ultraviolet light, the greater the damage. Tires damaged beyond repair will need to be replaced.
Invest in water-based tire oils to lubricate and seal cracks on the tires. Avoid using petrochemicals and silicone-based oils because they can strip protective waxes off the tire and expose them to higher levels of UV rays which increase the rate of degradation.
Apply two coats of water-based tire degreaser to a large sponge and wipe it on all parts of each tire. Spray the tires down with a water hose on lukewarm water to rinse away degreaser, dirt and grime. Allow the tires to air dry for two to three hours.
Saturate the tire with a water-based tire protection solution (found at most automobile shops). Reapply this solution every 20 to 30 days to increase the tyre's barrier to ozone and UV rays.
