What Tire Sidewall Indentations Mean

Noticing a dent in your tire’s sidewall can be concerning. At Les Schwab, we understand how easy it is to worry when you spot something unusual on your tires. The good news is that not every mark, dimple, or imperfection is a sign of trouble. In fact, many tire sidewall indentations or undulations are completely normal and won’t require repairs. However, outward-facing marks like bulges or bubbles should never be ignored and could require a professional inspection. Let’s take a look at tire undulations, what they mean, and when it might be time to get to Les Schwab for our expert tire services.

Understanding Tire Sidewall Indentations or Undulations

When looking closely at your tires, you might notice small, inward-facing dents, dips, or waviness along the sidewall. These are called indentations (small dips) or undulations (wave-like ripples).

The most important thing to know about sidewall indentations or undulations is that these marks are typically part of the tire’s construction process and not a sign of damage. Those indentations are where a tire’s internal cords or plies are layered. That layering strengthens the tire for safety and performance. Unless they become more pronounced or change over time, they usually aren’t a concern.

Tire Sidewall Protrusions or Bulges

Unlike indentations, protrusions can be a serious concern. Also called bulges or bubbles, they are noticeable bumps pushing out from the sidewall. Bulges usually form when the internal structure of the tire has been weakened. This can happen from hitting a curb, a deep pothole, or other debris. That damage then compromises the tire’s integrity and can lead to tire failure.

Driving on a damaged sidewall can be unsafe. If you spot a bulge or bubble in your tire, visit your local Les Schwab for an inspection.

What To Do if You Notice Changes in Your Tire Sidewall

Most noticeable indentations are harmless, while bulges may point to serious safety risks and require a trip to your local Les Schwab as soon as possible. Here’s what to watch for:

• Indentations/Undulations: Both indentations (small dips) and undulations (wave-like ripples) are normal sidewall variations caused by the tire’s construction. They are often harmless and typically do not affect tire performance. It’s best to monitor these for any changes.
• Protrusions or Bulges: Tires with bubbles, bulges, or protrusions in the sidewall are not safe to drive on and require immediate attention.

When you get your tires rotated every 5,000 miles, the professionals at Les Schwab will note any indentations, undulations, or bulges that need attention. However, if you notice an indent or protrusion on your tires growing larger, cracking, or changing shape over time, it could signal a developing issue that needs to be professionally inspected. Additionally, any sudden changes in the way your vehicle rides, such as pulling, vibrations, or unusual noises, may signal tire damage or other issues and should be checked as soon as possible.
