When a single tire wears noticeably faster than its partners, the problem is almost always isolated to that corner of the car - a bent part, a bad alignment angle that only affects one wheel, or a tire that was already on its last legs when installed.
Just replacing the worn tire without fixing the cause guarantees the new tire will wear out fast too. Always diagnose the corner before buying replacement rubber.
Camber, caster, or toe can be off on just one wheel after a curb strike or impact. A four-wheel alignment with printout will reveal which angle is out.
A previous impact bent a steering or suspension part on that corner. The alignment shop will say they cannot pull it into spec without replacement.
A stuck caliper, collapsed brake hose, or seized slider keeps light pressure on the wheel, generating heat and wearing the tire (and the brake) fast. Feel that wheel after a drive - hot points to a dragging brake.
A blown shock on one corner cannot keep the tire planted. Bounce test that corner - it should rebound once and stop.
A failing bearing lets the wheel wobble at speed, scrubbing the tire unevenly. Usually paired with a hum that changes when you turn.
Some tires have internal belt issues from the factory or from a previous patch/plug. If alignment and suspension check out, the tire itself may be the problem.
| What You Notice | Likely Diagnostic Step |
|---|---|
| Feel a hot wheel after driving | Dragging brake on that corner |
| Hum that changes with turning | Wheel bearing on that side |
| Bouncy/wallowy ride | Worn shock or strut |
| Recent pothole or curb hit | Bent part - get it inspected |

A localized issue on that corner: bent part from a pothole hit, alignment off on that wheel only, dragging brake creating heat, a bad shock, or a defective tire. Diagnose before replacing.
On all-wheel-drive cars, no - replace in pairs or sets of four. On front- or rear-wheel-drive, you can replace one but it should match the others in tread depth and model, otherwise it pulls the car.
Yes, if camber, caster, or toe is off on a single corner. A printout from a four-wheel alignment will show which angle is wrong.
After driving 10-15 minutes, carefully feel each wheel. The dragging-brake wheel will be noticeably hotter than the others. You may also smell hot brake material.
It will spread the wear across all four tires, but it does not fix the underlying cause. The wear will just shift to whichever tire is on that bad corner.
Yes, a loose bearing lets the wheel wobble, scrubbing the tread. Usually paired with a hum that gets louder with speed or changes when turning.
