Find the Leak and Determine Whether the Tire Can Be Safely Repaired
A flat or underinflated tire may be caused by a nail, screw, valve stem leak, bead leak, wheel damage, sidewall puncture, cracked rubber, or tire pressure monitoring system concern. A complete inspection is needed before deciding whether a repair is appropriate.
Tire repair depends on the location, size, angle, and condition of the damage. Punctures within the repairable tread area may sometimes be safely repaired, while sidewall damage, shoulder punctures, severe underinflation damage, or large openings generally require replacement.

Can Your Tire Be Repaired?
Repairable Tread Puncture
A small puncture located within the central tread area may be repairable if the tire has no internal or sidewall damage.
Shoulder or Sidewall Damage
Damage near the shoulder or sidewall generally requires replacement because these areas flex and carry heavy structural loads.
Internal Damage
A tire driven while severely underinflated may develop internal heat damage, liner damage, or cord separation that makes repair unsafe.
Not Every Flat Tire Is Caused by a Puncture
Valve Stem & TPMS
Valve cores, rubber stems, metal stems, TPMS seals, and sensor hardware may leak or corrode over time.
Wheel Bead Area
Corrosion, dirt, wheel damage, and improper tire seating may allow air to escape where the tire meets the wheel.
Wheel Damage
Bent or cracked wheels from potholes or curb impacts can cause repeated air loss even when the tire appears undamaged.
Why Internal Inspection Matters
A proper repair begins with removing the tire from the wheel and inspecting the inside for hidden damage. Repair decisions should be based on the puncture location, angle, size, tire condition, tread depth, and evidence of underinflation damage rather than simply inserting an external plug.
Driving on a Flat Tire Can Cause Permanent Damage
Even a short distance on a severely underinflated tire can generate excessive heat and damage the sidewall, inner liner, and internal cords. If the tire is completely flat, it is safer to use a spare, roadside assistance, or towing rather than continue driving.
Flat Tire Repair for Most Vehicle Types
What We Inspect, Test & Repair
Tire Pressure Check
We verify inflation pressure and compare it with the vehicle manufacturer’s recommended specification.
Puncture Inspection
Nails, screws, cuts, and other tread-area punctures are inspected for location, size, angle, and repairability.
Internal Tire Inspection
The tire may be removed from the wheel so the inner liner, sidewall, cords, and puncture area can be evaluated.
Valve Stem Inspection
Valve cores, rubber stems, TPMS stems, seals, and retaining hardware are checked for air leaks and damage.
Bead Leak Inspection
The tire-to-wheel sealing area is inspected for corrosion, debris, improper seating, and wheel damage.
Wheel Damage Check
Wheels are inspected for cracks, bends, corrosion, curb damage, and impact concerns that may cause air loss.
Puncture Repair
Repairable tread punctures are serviced using an appropriate internal repair method after the tire passes inspection.
Final Leak Test
After service, tire pressure, valve operation, sealing surfaces, and repair integrity are checked before installation.
Our Flat Tire Inspection & Repair Process
1. Pressure & Leak Check
We inspect tire pressure and locate air loss from the tread, valve stem, bead area, wheel, or another source.
2. Tire Removal
When appropriate, the tire is removed from the wheel for a complete internal inspection.
3. Repairability Decision
We evaluate puncture location, tire condition, tread depth, sidewall integrity, and evidence of underinflation damage.
4. Repair or Replacement Recommendation
We explain whether the tire can be safely repaired or should be replaced.
5. Approved Service
Repairable tires receive an appropriate internal repair, while damaged tires are replaced when necessary.
6. Final Verification
The repaired or replacement tire is inflated, checked for leaks, balanced when needed, and installed using proper lug torque.
When a Flat Tire Should Not Be Repaired
Sidewall or Shoulder Damage
Punctures, cuts, bubbles, or impact damage near the shoulder or sidewall generally require tire replacement.
Excessive Puncture Size
Large punctures, long cuts, irregular openings, or severe impact damage may exceed safe repair limits.
Internal Heat Damage
Tires driven while severely underinflated may develop internal liner damage, cord damage, or heat-related deterioration.
