Can you fix tire cupping?

Tire cupping can be the result of either poor vehicle alignment, manufacturing defect, or improper inflation. Tire cupping causes may vary also. If the cupping is not that severe, you could still fix it. But if it severe, then you don’t have any choice but to change it into a new one.

What does it mean when your tires are cupping?

Tire cupping is an uneven wear pattern, which occurs due to irregular up-and-down motions of a wheel (bouncing). It interferes with the proper contact of the tire with the road, scooping rubber in spots. The cupped tire may cause a rumbling noise when driving at higher speeds.

Is it safe to drive on cupped tires?

Driving with a damaged tire is not safe. You will not have as much control over your car as you should, and your tire is more liable to blow out. Furthermore, a cupped tire is often the result of broken struts or shocks, which means that continuing to drive your car could cause severe damage to the suspension system.

Will a burnout fix cupped tires?

If tires are cupped, etc from poor alignment, can a good long burnout round the tire again? Yes it can help. But only to the extent that you’ll need new (round) ones sooner! The more burnouts you do, the sooner you’ll have new rubber.

Can bad shocks cause tire cupping?

Absolutely: shocks and struts provide damping force to control tire movement. When the tires move excessively, they develop a “cupping” wear pattern that damages the tire. Other factors such as incorrect air pressure, worn suspension components or improperly aligned steering also causes uneven tire wear.

How can you tell if your tires are cupped?

If you notice the tires making an unusual noise or see patches where the tread is worn down more than others, you may have a problem known as cupping. Cupped tires have irregular smooth spots along the treads in the center or edge of the tire. Worn patches are usually about 3 inches in diameter.

What causes a tire to wear in the middle?

Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry the entire load. Tire tread wear on the edges of a tire will typically indicate inflation pressures are lower than specified.
