Regardless of how well tires are constructed, as they age they eventually begin to crack. While this isn't normally an issue for tires driven on regularly, tires that sit stationary for long periods of time are much more likely to crack. Anti-aging chemicals in tires are also more effective when a car is being driven regularly, and hopefully tires which show signs of aging have been replaced before they begin to crack.

Cracks typically begin to appear on either a tire's sidewall or between the tread. Some cracks are shallow and don't present much of an immediate danger to your safety. However, those that run deeper are more than a cosmetic concern-when these types of cracks appear, the tire should be replaced immediately, as it is prone to blowouts.

  • Tires usually don't crack until later in their lifespan, which is commonly referred to as weathered tires. However, cracking can be accelerated by multiple variables: Exposure to excessive heat, sunlight, weather, and vehicle exhaust
  • Excessive use of tire cleaners and abrasives
  • Constantly parking against or contacting curbs
  • Driving on improperly inflated tires
  • Overloading the tire's weight limit

While investing in a cover that extends below the tires can help with prevention, warranties will sometimes cover tire cracking, but they vary by manufacturer.
