Tire wear patterns: what they mean, how to fix them, and where to get help
Learning to read tire wear—on both tread and sidewall—can reveal issues with alignment, inflation, suspension, load, and driving habits. If anything below looks familiar, visit your local Discount Tire. We’ll check your tires, help diagnose the cause, and recommend the safest next step. You can also start with Treadwell, the same recommendation engine used in our stores, to match the right tires to your vehicle and driving needs. Start with Treadwell
Quick help:
- Free services: You can stop by any Discount Tire for a free tire air pressure check. Check tire air pressure tips
- Tire inspections: Professional tire inspections are available at every Discount Tire location. Schedule an inspection or find a store
- Alignment questions: If your wear pattern points to misalignment, see our wheel alignment guide and visit your nearest store for an inspection. We’ll advise on next steps.
Common tire wear conditions and causes
Alignment wear
Likely cause: Vehicle misalignment
What it looks like: Heavy wear on the inner or outer tread edge
What to do: Correct alignment to prevent further damage; depending on severity, affected tires may need replacement. Learn more in our wheel alignment guide
Underinflation (both shoulders worn)
Likely cause: Low tire pressure or a slow leak/puncture
What it looks like: Excess wear on both outer shoulders
What to do: Inflate to the manufacturer’s spec and repair leaks; severe cases may require replacement. Make monthly air checks or stop by for a free tire air pressure check.
Overinflation (center wear)
Likely cause: Overinflated tires
What it looks like: Center of the tread wears faster than the shoulders
Safety note: Replace immediately. Driving is unsafe once cords are visible.
Impact break (tread)
Likely cause: Hitting potholes, curbs, or debris
What to do: Have the tire inspected right away; replacement is often required. Also inspect wheels—damage can bend or crack rims. If needed, shop replacement wheels
Tread chunking
Likely cause: Frequent gravel/unpaved-road use or extended highway use of off-road/mud tires
What to do: Inspect and consider replacement if chunks compromise safety.
Belt separation (tread)
Likely causes: Manufacturing defect, underinflation, or overloading
Safety note: Replace immediately. Under applicable terms, defects may be covered by warranty.
Tread splice
Likely causes: Underinflation and overloading (excess heat buildup) or a manufacturing defect
Safety note: Remove from service right away. Defects may be eligible under warranty.
Common shoulder and sidewall conditions
Sidewall impact break
Likely cause: Hitting an object or curb (often at speed)
Safety note: Internal damage requires replacement. A professional must inspect the inner liner. Schedule an inspection
Ozone cracking/dry rot
Likely cause: Prolonged heat and sun exposure
What to do: Replace if cracking is significant; manufacturer warranty may apply depending on date code. Learn about dry rot
Reminder: Replace tires every 6 years regardless of tread, and remove from service after 10 years.
Heat ring
Likely cause: Driving while severely underinflated or carrying excessive load
Safety note: Internal damage is common; replacement is often required. If covered by our Certificates, this damage is covered.
Sidewall blister
Likely cause: Underinflation or overloading; may be a manufacturing defect
What to do: Professional inspection required; defects may be returned under warranty.
Sidewall bulge (impact bubble)
Likely cause: Impact with an object or curb
Safety note: Not repairable. Replace immediately.
Sidewall splice
Likely cause: Underinflation with excessive load/overheating; may be a manufacturing defect
Safety note: Replace immediately; defects may be eligible under warranty.
Torque cracks
Likely cause: Extreme torque from high-performance vehicles or heavy-duty towing
Safety note: Replace to prevent failure; possible defect coverage if not due to abuse.
What to do next
Get checked: Visit any Discount Tire for a free tire air pressure check and a professional tire inspection. We’ll measure tread, assess damage, and explain whether you need repair or replacement. Schedule an inspection or find your nearest store
Address the cause: If wear suggests misalignment, suspension issues, or over/underinflation, correcting the root cause protects your next set of tires. See our wheel alignment guide
Protect your purchase: Add a Discount Tire Certificate for Repair, Refund or Replacement when you buy or within 30 days. If nonrepairable damage occurs while the tire has more than 3/32" of tread and is within 3 years of purchase, we’ll refund the tire’s full purchase price toward a replacement—no prorating.
