You walk out to your car, glance down, and spot it — a nail sitting right in the middle of your tread. Your stomach drops. You’re already late, it doesn’t look completely flat, and you’re wondering if you can just drive to work and deal with it later. Here’s the honest answer: it depends — but ignoring it is never the right call. This guide covers everything Calgary drivers need to know about nails in tires, what to do immediately, and when to stop driving altogether.
What to Do if a Nail Gets in Your Tire?
The moment you discover a nail in your tire, follow these steps:
Step 1 — Don’t pull it out
This is the most important rule. The nail is acting as a plug, temporarily sealing the hole it created. Pull it out and you’ll have immediate air loss — potentially a flat tire on the spot. Leave it exactly where it is.
Step 2 — Check your tire pressure immediately
Use a tire pressure gauge or check your TPMS reading on the dashboard. If the pressure is at or near normal — the nail may have created a slow leak rather than an immediate flat. If it’s significantly low — don’t drive on it.
Step 3 — Visually inspect the nail’s location
Look at where exactly the nail is sitting. Is it in the centre of the tread? Or is it closer to the sidewall or shoulder? Location determines whether the tire can be repaired at all.
Step 4 — Drive carefully and directly to a tire shop
If pressure is holding and the nail is in the central tread area, you can drive carefully to a nearby tire shop for a proper inspection and flat tire repair at Good Tire. Keep your speed low, avoid highways, and go directly — no detours.
Can I Drive on a Tire With a Nail in It?
Sometimes — but only under specific conditions and only for a short distance. Here’s the breakdown:
You can drive carefully if:
- Your tire pressure is at or near normal
- The nail is in the central tread area
- The tire shows no visible bulging or sidewall damage
- You’re driving slowly and directly to a tire shop — not running errands
You should not drive if:
- Your tire pressure is significantly low
- The nail is near or on the sidewall
- The tire looks visibly flat or deformed
- Your TPMS warning light is on and staying on
- You can hear air escaping
Even in the best case scenario — nail in the tread, pressure holding — this is not a situation you drive around in for days hoping for the best. Every kilometre you drive increases the risk of the nail working deeper, the leak getting worse, or the tire failing completely. Get to Good Tire as soon as possible and let us assess it properly.
Can a Tire Be Fixed With a Nail in It?
Yes — but only if it meets all of these conditions:
- The puncture is in the central three-quarters of the tread
- The nail created a hole no larger than 6mm in diameter
- The tire has not been driven on while flat
- There is no sidewall or shoulder damage
- The tire has not been previously repaired in the same area
If all of those conditions are met, a certified technician will remove the nail, ream the hole, apply a proper patch-plug combination from the inside of the tire, remount, and balance it. A repair like this — done correctly — can last the remaining life of the tire.
If any of those conditions aren’t met, the tire needs to be replaced. At Good Tire in Calgary, we inspect every nail puncture honestly before recommending a repair or replacement — you’ll always know exactly why we’re recommending what we are.
Can I Just Pull a Nail Out of My Tire?
No — and this is one of the most common mistakes drivers make. Pulling the nail out yourself causes immediate air loss. What was a slow, manageable leak becomes a flat tire on the spot — potentially while you’re still on the road.
There’s also a second problem: once the nail is out, air escapes quickly and the tire can partially collapse before you can do anything about it. Driving even a short distance on a collapsed tire damages the inner liner, the sidewall, and potentially the rim — turning a $40 repair into a $300+ replacement.
Leave the nail in. Drive carefully and slowly to a tire shop and let a technician remove it safely with the proper equipment and a repair ready to go immediately after.
How to Tell if the Nail Location Makes It Repairable
Not all nail punctures are equal. Here’s a simple way to assess the situation before you drive anywhere:
Repairable zone:
The central area of the tread — roughly the middle three-quarters of the tire’s width. If the nail is sitting squarely in the middle of the tread pattern, there’s a good chance it’s repairable.
Not repairable:
- Nail is on or near the sidewall — the area that flexes constantly while driving
- Nail is on the shoulder — where the tread meets the sidewall
- Multiple nails in the same tire
- Nail created a hole larger than 6mm
If you’re unsure — don’t try to judge it yourself. Bring it to Good Tire and we’ll tell you within minutes whether it can be fixed or needs replacing. For more on what’s repairable and what isn’t, read our guide: How to Change a Flat Tire in 8 Simple Steps.
What Happens if You Ignore a Nail in Your Tire?
Ignoring a nail — even a slow leak — is a gamble that gets more dangerous the longer you wait. Here’s what happens over time:
- Hour 1–24 — The nail may hold the pressure reasonably well, but air is slowly escaping with every rotation
- Day 1–3 — Pressure drops noticeably. Handling becomes less precise. Fuel economy quietly worsens
- Day 3+ — The tire becomes significantly underinflated. The sidewall starts flexing more than it should, generating heat and internal stress
- Eventually — The internal structure breaks down. What started as a $40 nail repair becomes a blowout at the worst possible moment
Calgary roads don’t give you much warning — and a blowout on Deerfoot Trail or the Ring Road at 100 km/h is a serious safety risk. Don’t let a nail you spotted in your driveway turn into an emergency on the highway.
Temporary Fix — Should You Use a Tire Repair Kit?
If you can’t get to a tire shop immediately, a tire plug kit can buy you some time. Insert a plug into the nail hole after removing the nail, inflate the tire, and drive carefully to the nearest tire shop. This is a temporary bridge — not a permanent solution.

Frequently Asked Questions – Nail In Tire
How long can you drive on a tire with a nail in it?
If pressure is holding and the nail is in the central tread area, you can drive carefully for a short distance — enough to reach a tire shop. Keep your speed under 80 km/h and go directly. Don’t drive on it for days hoping it holds. Every kilometre increases the risk of the leak worsening or the tire failing completely.
Can a nail cause a blowout?
Yes — if left long enough. A nail creates a slow leak that gradually drops your tire pressure. Once pressure gets low enough, the tire overheats from the increased sidewall flex and the internal structure breaks down — that’s a blowout. A nail caught early is a simple repair. A nail ignored for days can become a dangerous emergency.
Can I leave a nail in my tire overnight?
If the pressure is holding and you genuinely cannot get to a tire shop until morning — yes, you can leave it overnight. Check the pressure before you leave and again in the morning. If it’s dropped significantly overnight, don’t drive on it. Get it to Good Tire in Calgary first thing — we’re open from 9 AM, seven days a week.
How do I know if a nail is in my tire?
Common signs include: a TPMS warning light that keeps coming back after inflation, one tire consistently losing pressure, a faint hissing sound near a tire, or visible handling changes. Sometimes you’ll spot it visually — a nail or screw sitting in the tread. If you suspect something is wrong but can’t see it, bring it in and we’ll inspect it.
Can a nail burst a tire?
A nail alone rarely causes an immediate blowout — it typically creates a slow leak rather than a sudden burst. However, if the nail damages the sidewall, or if the tire is driven on while significantly underinflated due to the nail leak, a blowout becomes a real risk. The longer a nail is left in, the higher that risk becomes.
Can I ignore a nail in my tire?
No — not safely. Even a slow leak left unaddressed puts you at risk of a blowout, damages your rim if the tire goes flat, and worsens your fuel economy and handling every day. A nail caught early is one of the cheapest tire repairs there is. Ignored long enough, it becomes one of the most expensive — and dangerous — outcomes on the road.
