Slow Tire Leak: What to Check Before Your Repair Call
A tire that repeatedly loses air needs its leak source assessed. A tread puncture, valve, tire-to-wheel seal or wheel condition may be involved; topping it up does not identify the cause.

At a glance
A tire that repeatedly loses air needs its leak source assessed. A tread puncture, valve, tire-to-wheel seal or wheel condition may be involved; topping it up does not identify the cause. Record which tire is affected, measured pressure changes and any recent work or impact before contacting the shop.
- Record the affected tire and measured pressure change.
- Mention recent fitting work or impact.
- Ask about leak assessment before choosing repair or replacement.
Start with a useful pressure record
If the vehicle is safely parked and the tire has no obvious damage, record its cold pressure with a gauge. Use the vehicle’s tire-information label or manual for the specified pressure. A visual glance cannot establish that a tire is properly inflated.
- Record the pressure and date rather than guessing.
- Tell the shop whether one tire or several lose air.
Slow leaks from the tread, valve or bead seal
A slow tire leak may come from a tread puncture, a leaky valve stem, the bead seal where the tire meets the wheel, or wheel damage. These are different concerns. Ask for the tire-and-wheel assembly to be assessed so the findings determine whether tire repair, valve work or another next step is appropriate.
- Mention previous puncture repairs and wheel damage.
- Share whether the concern started after installation or a curb impact.
Pressure loss can change the next step
Do not continue driving on a flat or seriously underinflated tire. Rapid pressure loss, a bulge, a cut or a change in control needs prompt professional attention. If safe transport is uncertain, arrange appropriate assistance instead of attempting to reach the shop on that tire.
- Follow the vehicle manual’s flat-tire instructions.
- Do not remove an embedded object to investigate the leak.
Ask for assessment scope before authorizing repair
Call Father Auto with your observations to discuss the next step and confirm an appointment. Ask what the assessment covers and how findings will be explained. Toronto and GTA drivers should confirm arrangements for the Scarborough location before travelling; a repair cannot be guaranteed from a phone description.
- Ask whether the assessment charge is separate from repair.
- Request replacement options only if the tire is unsuitable for repair.
Have these details ready when you call
- Vehicle year, make and model
- Affected tire and cold-pressure readings
- Approximate time between pressure drops
- Tire size and previous repair history
- Recent installation, pothole or curb impact

Contact UsCommon questions
Can a slow leak always be patched?
No. The source and tire condition matter. A tread puncture, valve leak and wheel-sealing problem can require different work; the assembly needs assessment first.
Does adding air fix the problem?
Adding air does not identify or repair the leak. Persistent pressure loss warrants assessment, and a flat or seriously underinflated tire should not be driven on.
What should I ask when I call?
Ask about leak-assessment scope, appointment arrangements and how any repair or replacement will be quoted. Have your pressure record and tire size ready.
