Tire Wear Pattern Checker
Your tires leave clues about your suspension. Select how your tire is wearing out to identify bad alignment, worn shocks, or improper inflation.
Direct Answer
Wear on one edge means bad alignment (camber/toe). Wear in the center means over-inflation. A wavy, cupped pattern means worn shocks or struts.
Tire Wear Patterns
Warning: This tool provides general guidance, not a diagnosis. If the vehicle is running poorly, pull over immediately.
Select a symptom to see what it means and what to do next.
Assumptions we made
- Tires are standard passenger/light truck tires
Important limitations
- Cannot identify the exact bent suspension component causing the bad alignment
Step by step
How to use this tool
- 1
Inspect all four tires and note where the tread is worn.
- 2
Select the matching wear pattern: center, edges, one side, cupping/scalloping.
- 3
Read the diagnosis: center = overinflation, edges = underinflation, one side = alignment, cupping = bad shocks.
- 4
Address the root cause before buying new tires.
Decision context
What this calculator helps you decide
Use Tire Wear Pattern Checker when you need a quick, structured answer before you spend money, approve work, prepare a trip, compare options, or share information with a buyer, seller, shop, lender, or insurer. Enter the inputs you already know, review the result, then use the assumptions and limits below to decide what to check next.
Inputs and outputs
Start with the inputs that most affect this decision: Wear Pattern. The output is meant to make the next step easier to compare, not to replace a written quote, inspection, policy document, loan disclosure, or local rule.
The main outputs are Likely Issue, Severity, Next Steps. If one input is uncertain, change that value and compare the result again before treating a single estimate as final.
Best-use cases
This page is built around the search intent: identify tire wear pattern, tires wearing on inside edge, cupping tire wear. It is most useful when you want to narrow a decision, prepare better questions, or avoid missing a cost, risk, fitment issue, paperwork step, or ownership detail.
Keep the assumptions visible while using the result. If your vehicle, location, driving pattern, quote, loan, insurance policy, or listing situation is unusual, use this as a planning screen and verify the final decision with the relevant document, professional, or local requirement.
Methodology
How the estimate works
Inputs, outputs, and calculation logic.
Logic
Maps tread degradation patterns to the physical forces (pressure, angle, bounce) causing them.
