Tire Sidewall Crack Repair
Ideally, those with broken sidewalls should simply replace the tire as opposed to repairing it. The repairs are just not considered to be reliable or effective. Even if the glue of a professional sidewall repair holds, it is not a permanent solution. Plus, you don't know when the glue might decide to give out. Despite it’s name, Dry Rot is not a rot that sets in as you would see on a tree for example. It’s actually just the name for the physical symptoms of the rubber compounds in your tire becoming damaged, drying out and starting to crack. How Do it Affect Your Tires? It will present as dry and cracked patches on your tire wall.
Tire Sidewall Crack Repair
Notable indicator that a tire is old is the presence of numerous, tiny cracks in the sidewall. DETAIL SHOWING AGE CRACKS IN TIRE SIDEWALL The tires used on vehicles that are driven infrequently or accumulate low annual mileage are more likely to experience cracking because long periods of parking.
Evaluate the extent of the sidewall damage. The sidewall's threads must be intact to justify a repair job. Holes wider than 1 inch or longer than 4 inches are irreparable. More than two large cracks on the sidewalls also rules out repair. Replace the tire in such cases. However, the outer tire rubber doesn't hold the air, the inner liner holds the air in. Thus a tire puncture means the inner liner gets a hole, and the inner liner must be properly patched. A tire sidewall slice is quite common for 4x4 off roading trips, which I have done, and not a reason to replace the tire. Here is a tire damage inspection chart.

My father is notoriously frugal, and I tell him he should replace his old dry-rotted tires even though they still have plenty of tread. Can you please explain why I'm right?
I think our dads might be brothers. Tire replacement is pretty straightforward to the cost-conscious: when the tread wears down or a hole can't be patched. The reality is more nuanced than that. Tires are complex components that undergo amazing stresses during even the most mundane of drives. It took the better part of 50 years and a world war before motorists could depend on reaching a far-away destination without fixing one or two flats. As rubber technology and steel-belting techniques improved, tires became a very reliable part of the carwe just don't expect blowouts and punctures.

Tires do degrade over time, though, and that process is called dry rot. Oils and chemicals in the rubber compound start to evaporate or break down because of UV exposure. The rubber loses its flexibility and begins to crack at the surface, and the structure becomes more and more brittle (think of a really old rubber band), leading to sidewall damage and eventual failure. And we're not talking 'Oh, I'll just fill it up and drive on it'; this is a complete loss of function. You might even see tread start to separate. It's good practice to replace tires as soon as you see signs of dry rot, to prevent blowouts and the subsequent loss of vehicle control. Even if there are no signs of rot, the industry standard is to swap out tires before they hit 10 years old, and some tire companies recommend replacement as early as six years after manufacture.
