We don't blame it, really. Tires are subjected to one of the harshest environments experienced by any consumer product. They roll over bumps, cracks, snow, ice, salt, rocks...and they get covered in brake dust and chemicals, not to mention the fact that they're repeatedly exposed to the sun. Today's manufacturing processes infuse tires with anti-aging elements, but eventually the elements get the best of them and that's when they begin to crack along the surface.
Whether you call it "weather checking" or "weather cracking," maybe even "ozone cracking," it's cracking just the same. Most often you'll notice the damage along the sidewalls, and if the damage goes deep below the surface—odds are good it just might be time for a new tire. And typically, cracking only occurs later in the life of the tire but there are cases where it happens in the early years. Lucky for you, most tire manufacturers cover this in their warranties. Just in case.
Take good care of your tires and you'll prolong the inevitable crack, but again, if you've noticed excessive cracking and feel as though it's time for something new—feel free to shop our inventory by vehicle to find suitable replacements in no time at all.
