Tire cupping—worn, cup-shaped indentations on the tread—is a common issue that shortens tire life. It’s usually a sign of an underlying problem, so fixing the cause is just as important as addressing the wear itself.
First, recognize the signs. Cupping looks like small, shallow “cups” in the tread, often accompanied by a rumbling noise while driving. It’s caused by loose or worn suspension parts (like shock absorbers, struts, or control arm bushings). When these parts fail, the tire bounces instead of staying flat on the road—creating the cupped wear pattern.
To fix it, start by having a mechanic inspect your suspension. They’ll replace any worn parts (shocks are the most common culprit). Once the suspension is fixed, check if the tires can be saved. If cupping is mild, rotating the tires may help balance wear. But if the wear is deep or uneven, you’ll need to replace the tires—severe cupping can’t be reversed and reduces traction.
Prevent future cupping by servicing your suspension regularly. Have shocks and struts checked every 30,000 miles (or as recommended in your manual). Avoid hitting potholes or curbs, which damage suspension parts. By keeping your suspension in good shape, you’ll stop cupping before it starts.
