What uneven tire wear is telling you about your truck
Tires are honest. They wear the way the truck makes them wear, so a worn tire is a report on everything holding it to the road. Learn to read the pattern and you can fix the cause before you buy the next set, instead of after. Here is what the common patterns mean.
Worn in the center
When the middle of the tread is gone but the edges still have life, the tire has been running overinflated. Too much pressure crowns the tire so only the center touches the road. Drop the pressure to spec for the load and the whole tread starts carrying again.
Worn on both edges
The opposite pattern, both shoulders worn while the center holds, means the tire has been running underinflated or overloaded. The tire flattens out and the edges scrub. This one also runs hot, which is how underinflated tires end up as the strips of rubber you see on the shoulder of the highway.
Cupping or scalloping
Dips spaced evenly around the tire, almost like a wave, usually mean the tire is bouncing instead of rolling. That points to worn shocks or other tired steering and suspension parts that are letting the wheel hop. New tires on a truck that cups will just cup again.
Feathering
Run your hand across the tread. If it feels smooth one way and sharp the other, the edges of the tread blocks are wearing at an angle. That is a toe alignment problem. The front tires are being dragged slightly sideways every mile, and it eats them fast.
Worn on one side
If one shoulder is gone and the other is not, the tire is leaning. That is a camber or alignment issue, and on the front end it often comes with worn kingpins or tie rod ends. The fix is the front-end part, not just the tire.
Flat spots
A patch worn flat in one or two places usually means the brakes locked the wheel at some point, or the truck sat in one position long enough to take a set. Flat spots make a thump you can feel, and a bad one is its own violation.
Read it, then fix it
We look at the wear before we sell you tires, because the pattern tells us whether you have a tire problem or a truck problem. Sometimes it is just pressure. Sometimes it is alignment or the front end. Either way, fixing the cause is what makes the new tires last. Pair it with a preventive maintenance visit and we keep an eye on it before it costs you a set. Call 720.312.7095.
