Tire inspection checklist
How do you inspect your tires at home and what should you check?
A home tire check can find reasons to stop or arrange inspection, but it cannot certify a tire as safe. Check cold pressure against the vehicle placard, measure tread in several places, inspect both sidewalls and the tread, note the complete DOT date code, and investigate new vibration, noise or repeated pressure loss. Stop using a tire with a bulge, exposed or damaged cords, separation or rapid pressure loss; use roadside assistance when needed.
How-to steps
- Check tread and pressure Measure tread depth across the width and set cold pressures from the vehicle placard rather than the tire sidewall maximum.
- Inspect sidewalls and valves Look for bulges, cracks, cuts, exposed cords, embedded objects, damaged valves, and missing caps.
- Act on urgent defects Replace or professionally inspect tires with bulges, cords visible, severe cracks, or tread below the legal minimum.
What to do now
- Stop using the tire
- Do not continue on a tire with a bulge, exposed or damaged cords, tread or sidewall separation, rapid pressure loss, or damage after it was driven flat. Use the spare or roadside assistance.
- Arrange an inspection
- Have a trained tire professional inspect any cut, crack, puncture, hard impact, new vibration, noise, or repeated pressure loss before normal driving. An outside visual check cannot rule out hidden internal damage.
- Apply conservative repair limits
- USTMA limits repair consideration to a tread-area puncture no larger than 6 mm. The tire must be removed and inspected internally, and the injury channel plus inner liner must both be repaired. Shoulder and sidewall damage are excluded; tire-maker policy still controls.
Safety sources
These sources support the triage and repair boundaries above. They do not replace a hands-on inspection or the tire manufacturer’s policy.
Checked:
What this check can and cannot prove
Good lighting, a pressure gauge and a tread-depth gauge can reveal visible concerns. They cannot expose hidden impact damage, inspect the inner liner while mounted, confirm repairability or replace maker instructions. Improvised tread checks and fixed crack-depth grades are not reliable approval methods. Legal tread rules depend on jurisdiction.
Practical tire inspection checklist
| Check | What to look for | Next step |
|---|---|---|
| Cold pressure | Measure before driving and compare with the vehicle placard or manual, including load-specific values. | Correct as specified. Repeated or rapid loss needs prompt inspection; appearance is not a pressure check. |
| Tread | Use a depth gauge in several main grooves and positions; note wear bars and uneven areas. | Compare with current local law and maker guidance. Near-limit, uneven or rapid wear needs assessment. |
| Sidewalls and tread | Look for bulges, cuts, cracks, exposed cords, missing rubber, deformation or separation. | A bulge, cord damage, separation or rapid loss means stop using the tire. Other damage still needs inspection. |
| Embedded object | Look for nails, screws or other objects and check whether pressure is falling. | Do not pull it out roadside. If pressure falls, stop safely and arrange assistance or a demounted inspection. |
| Age and identification | Read the last four digits of the complete DOT TIN as production week and year. | Age is context, not clearance. Follow the exact tire and vehicle makers’ guidance and recalls. |
| TPMS | Treat a warning or malfunction according to the vehicle manual and verify with a suitable gauge. | TPMS does not replace pressure checks; no warning does not prove correct pressure or condition. |
| Wear and symptoms | Note uneven wear, new vibration, noise, pull, impact history or recurring pressure change. | Do not diagnose from the pattern alone. Sudden or persistent symptoms need inspection before normal driving. |
Choose the next action
| State | When it applies | Action |
|---|---|---|
| Stop now | Bulge, exposed or damaged cords, separation, rapid pressure loss, or damage after running flat. | Do not continue normal driving. Use the approved spare procedure or roadside assistance. |
| Inspect before normal driving | Cut, crack, puncture, hard impact, new vibration or noise, repeated loss, or uncertain repair. | Have a trained tire professional inspect the tire, demounted when required. |
| Continue routine monitoring | No stop or inspection trigger was found and measured values meet applicable requirements. | Record and monitor. This does not guarantee hidden condition or future performance. |
When to repeat the check
- Follow the vehicle and tire makers’ inspection and cold-pressure schedule.
- Check before a long trip and after a hard impact, major load or temperature change.
- Recheck after a warning, new vibration or noise, visible damage or unexplained pressure loss.
- Include the spare and rarely used tires; low mileage does not stop aging.
Limits and related checks
This is general screening, not a roadworthiness certificate, repair authorization or diagnosis. The exact tire, wheel, vehicle, load, history and local rules still control.

Seasonal check
Planning a long summer drive?
Use the budget and running-cost tools before a trip, especially if the current tires are worn or the replacement size changes diameter.
