Inner or Outer Edge Wear — Camber Problems
If your tires are wearing significantly on just the inner or outer edge, the most likely cause is a camber problem. Camber is the inward or outward tilt of the tire when viewed from the front. Negative camber — tire tilted inward at the top — wears the inner edge. Positive camber wears the outer edge. In Cleveland, the most common cause of camber problems is pothole damage. One hard hit on Carnegie Avenue or a frost heave on a side street in Collinwood can bend a control arm or knock the subframe out of spec. The alignment looks fine until you check it and find one wheel sitting at negative 2 degrees. We see this constantly from November through April.
Feathered or Scalloped Wear — Toe Problems
Run your hand across the tire tread. If it feels smooth one direction and rough the other — like petting a cat the wrong way — that is feathered wear, and it is caused by a toe alignment problem. Toe refers to whether the front of the tires point slightly inward or outward. Even a small toe misalignment causes the tires to scrub sideways slightly with every rotation. Over thousands of miles, that scrubbing creates the feathered pattern. Toe can drift from normal wear on tie rod ends, or from a pothole impact. Either way, an alignment fixes it. At Nick's, alignment runs $80 to $100 and we check all angles — camber, toe, and caster.

Center Wear vs Edge Wear — Inflation Problems
This one is the easiest to fix. If the center of the tread is worn but the edges are fine, you have been running too much air pressure. The over-inflation makes the tire balloon in the middle, concentrating all the wear in the center strip. If both edges are worn but the center still has good tread, you have been under-inflated. The tire sags and the edges carry more load. Cleveland temperature swings make this worse — your tires are at the right pressure in October and 6 PSI low by January. Check your pressure monthly. The correct number is on the sticker inside the driver door, not on the tire sidewall.
Cupping or Scalloping — Suspension Wear
Cupped tires have a wavy, scooped-out pattern that you can feel by running your hand over the tread. It looks like someone took small bites out of the rubber at regular intervals. This is almost always caused by worn shock absorbers or struts. When the shocks are weak, the tire bounces slightly instead of maintaining consistent contact with the road. Each bounce causes a high-pressure spot, and over time those spots wear faster. You will also hear a rumbling noise from cupped tires at highway speed. Replacing the shocks and rotating or replacing the tires fixes the problem.
What To Do When You Spot Uneven Wear
Do not just buy new tires and hope for the best. If you put new tires on without fixing the underlying cause, the new set will wear unevenly too. Bring the car to Nick's Tire and Auto for a free tire inspection. We will identify the wear pattern, check alignment, measure suspension components, and tell you exactly what needs to be addressed before you invest in new rubber. Used tires start at $60, new tires at competitive prices, and alignment at $80 to $100. We are at 17625 Euclid Ave, Euclid — call (216) 862-0005 or walk in any day. See our [tire inventory](/tires) and [alignment service](/alignment).
