What causes rear tires to scallop?
Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Shocks and struts are the most likely culprit because they provide damping force to control tire movement. When the tires move excessively, the scalloped pattern can appear.
What causes tires to scallop on the inside?
Can you fix a scalloped tire?
Take the vehicle to the auto repair shop and have them change the shocks. Then have the shop put the cupped tires on the rear of the car until they wear smooth again. If the cupping is too severe, the tire shop may be able to use a tire-shaving machine to even them out.
Can you drive on scalloped tires?
TOM: Unfortunately, it’s really not safe to drive on cupped tires. They have indentations in them. So every time the tire rotates, there are high spots that aren’t touching the road. That means you have less traction, and less ability to stop and turn.
How do you know if your tires are cupped?
Tire Noise: You may notice a rhythmic sound, louder than your usual road noise, if your tires are cupped. This is due to those unevenly worn patches of tread rubber causing odd noises while rolling.

What causes scalloped marks on the tread of a tire?
Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Worn shock absorbers or unbalanced tires can also cause cupping, but the cupping would typically be more indicative of a concentric pattern.
What should I do about scalloped tire wear?
Rotating the scalloped tired to the rear may even out the tread wear because scalloping is a symptom seen usually only in front wheels. Ensure that tires are inflated to the correct pressure. And also verify that the load you’re putting on the vehicle corresponds with your suspension’s load-bearing limit.
What does it mean when your tire tread is worn?
Toe angle geometry can also be greatly affected by changes in suspension height. Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts.
What does tread wear tell you about suspension?
Tire tread wear can tell you a lot about a suspension. Most specifically, it can tell you if the angles, inflation and components are within specification. Here are the most common tread wear patterns and what causes them. Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high.
