The Tire Doctor will see you now. If you notice a problem with one of your tires, we can diagnose it here. Which of the following best describes the problem?
Normal Radial Sidewall
Indentations are quite natural on radial tires (which most all tires on the road are) and will not affect performance. Your tires feature one or more layers of fabric cord within its sidewall construction that run parallel to each other. (Steel cords are used within the tread.) Where the cords overlap, there is often slight indentation. (For more information on tire construction, click here.)
Bulging, however, is not normal on a tire. It signifies that there is a gap between the cords, and must be replaced immediately. Do NOT drive on this tire, even down the road to a tire retailer.
Remember this easy math: indentations = good; bulges = bad.
Bulge or Bubble
Damaged Tire That Needs to Be Replaced
A tire with a bulge or bubble cannot be repaired. Damage and Replacement Issues:
- A bulge or bubble on the sidewall of a tire generally indicates damaged cords caused by a severe impact.
- Damaged cords often are accompanied by a visible break in the inner liner.
- If cords have been damaged, air has infiltrated into the plies and can result in a bulge.
