Nail or screw in tyre
A nail or screw in your tyre does not always mean the tyre needs replacing. If the puncture is small, located in the central tread, and the tyre has no internal damage, a professional repair may be possible. You should not pull the object out yourself. Check the tyre pressure and arrange a proper tyre inspection.
This guide explains what to do after finding a nail or screw in your tyre, how to check for air loss, whether driving is safe, and when repair or replacement is needed. The main decision depends on puncture location, tyre pressure, damage size, and internal tyre condition.
What should you do if you find a nail or screw in your tyre?
If you find a nail or screw in your tyre, stop safely, check the tyre condition, and avoid removing the object yourself. The nail or screw may be slowing the air leak, especially if the tyre still looks inflated. A pressure check and professional inspection give the safest repair or replacement decision.
What should you check before driving?
Check the tyre pressure, object position, tyre shape, sidewall condition, and dashboard warning lights before driving. A tyre pressure gauge gives a better reading than visual inspection because a slow leak can leave the tyre looking normal for a short time.
Park the vehicle away from traffic.
Check the tyre pressure with a gauge.
Look at where the nail or screw is located.
Check whether the object is in the central tread, shoulder, or sidewall.
Look for cuts, bulges, exposed cord, or visible tyre damage.
Call a tyre fitter if the tyre is losing pressure or the damage is near the sidewall.
What should you avoid doing first?
Avoid pulling the nail or screw out, driving at high speed, overloading the vehicle, or ignoring pressure loss. A screw can act like a temporary plug inside the puncture hole, and removing it can make the tyre lose air faster.
Action Risk Controlled Best Next Step Leave the object in place temporarily Sudden air loss after removal Book a professional tyre inspection Check tyre pressure Hidden slow leak Compare pressure readings over time Avoid motorway driving High-speed blowout risk Use mobile tyre help or visit the nearest safe garage
Should you remove the nail or screw from the tyre?
You should usually leave the nail or screw in the tyre until a tyre technician inspects it. The object can reduce air escape by filling part of the puncture hole. Removing it without repair equipment can turn a slow leak into a flat tyre.
Why can removing the object make the tyre deflate?
A nail or screw can create a puncture path through the tread and inner liner. The metal object may partly block that path while the tyre remains under pressure. Once the object is removed, air can escape faster through the open hole.
When should a professional remove the nail or screw?
A tyre technician should remove the object when the vehicle is secure and the tyre can be inspected properly. A proper check looks at puncture angle, damage size, repair zone, inner liner condition, and signs of internal tyre damage.
Situation Remove It Yourself? Reason Tyre still holding pressure No The object may be slowing air loss Tyre rapidly deflating No Roadside removal may make the situation worse Tyre being inspected by a fitter Yes, by the fitter The tyre can be checked and repaired or replaced immediately
How can you tell if the nail or screw has punctured the tyre?
You can tell if a nail or screw has punctured the tyre by checking tyre pressure, looking for air bubbles, and watching for TPMS warning lights. A tyre can look inflated while losing air slowly, so a pressure check gives a more reliable answer.
How do you check tyre pressure after finding a nail or screw?
Use a tyre pressure gauge and compare the reading with the correct pressure listed in your vehicle handbook or door-pillar label. Recheck the same tyre after a short parked interval. Falling pressure suggests an active air leak.
If your dashboard shows a pressure warning after finding the object, a TPMS service can help diagnose sensor faults, pressure loss, and tyre pressure monitoring problems.
How does the soapy water test show an air leak?
A soapy water test can show air escaping from the tyre. Spray soap solution around the nail, screw, valve, or tread area. Repeated bubbles around the object usually mean air is leaking from the puncture point.
How does a TPMS warning help confirm pressure loss?
A TPMS warning helps identify pressure loss before the tyre looks flat. The system can alert the driver when one tyre drops below the expected pressure range. A missing TPMS warning does not prove the tyre is safe because some leaks are slow or recent.
Diagnostic Method What It Checks What the Result Means Pressure gauge Tyre pressure reading Falling pressure suggests an active leak Soapy water Bubbles around the puncture point Bubbles confirm escaping air TPMS warning Dashboard pressure alert The tyre may be underinflated Professional inspection Inner liner and tyre structure Repairability can be confirmed
Drivers who see repeated pressure loss should also read our guide on can my puncture be repaired before using the tyre for longer journeys.
Can you drive with a nail or screw in your tyre?
You should avoid normal driving with a nail or screw in your tyre because pressure loss can worsen without warning. Limited, low-speed driving to a safe place or nearby tyre professional may be possible when pressure stays stable, but motorway driving is not recommended.
Can you drive if the tyre is not losing air?
You may move the vehicle carefully if the tyre holds pressure, but stable pressure does not prove the tyre is undamaged. A shallow nail may only sit in the tread, while a deeper screw may reach the inner liner and start leaking later.
Can you drive on the motorway with a nail or screw in the tyre?
You should not drive on the motorway with a nail or screw in the tyre. Motorway speed increases heat, pressure stress, and tyre failure risk. A slow leak can become a serious pressure loss at higher speed.
How far can you drive with a nail or screw in the tyre?
No fixed safe distance exists because tyre pressure, puncture location, vehicle load, speed, and internal damage all change the risk. A tyre holding pressure may reach a nearby inspection point, but a tyre losing pressure should not be used for daily driving or long journeys.
Tyre Condition Can You Drive? Best Action Object in central tread and pressure stable Limited cautious driving only Drive slowly to inspection or book a fitter Slow pressure loss Risky Inflate only if safe and visit the nearest fitter Rapid air loss No Call 24/7 emergency tyre fitting Sidewall damage No Arrange tyre replacement inspection Flat tyre No Stop driving and request mobile tyre help
Can a tyre with a nail or screw be repaired?
A tyre with a nail or screw can be repaired when the puncture is in the repairable tread area, the hole is within the safe repair limit, and the tyre has no internal damage. Sidewall, shoulder, large, angled, or flat-driven punctures often require replacement.
When is a puncture in the central tread repairable?
A puncture in the central tread has the strongest repair potential because this area is designed for road contact and can usually accept approved internal repair methods. A technician checks the object angle, hole size, tread depth, inner liner, and previous repairs before approving repair.
When the tyre is suitable for repair, our mobile tyre repair service can help you avoid driving on a damaged tyre.
When does puncture size make repair unsafe?
Puncture size matters because a large hole can weaken tyre structure and prevent a secure repair. A small central tread puncture may be repairable, but a large puncture, torn hole, or damaged inner liner can make replacement safer.
Why does internal tyre condition affect repairability?
Internal tyre condition affects repairability because driving underinflated can damage the carcass, belts, and inner liner before external damage becomes obvious. A tyre that looks repairable from the outside may be unsafe after internal inspection.
Damage Location Repair Possible? Likely Outcome Central tread Sometimes Professional puncture repair may be possible Tread groove Sometimes Repair depends on depth, angle, and hole size Shoulder Usually no Replacement is commonly required Sidewall No Replacement is the safe outcome Large puncture No Replacement is likely Driven flat Usually no Internal damage inspection is needed

When does a nail or screw mean the tyre must be replaced?
A nail or screw usually means tyre replacement when the damage is in the sidewall or shoulder, the puncture is too large, the tyre has been driven flat, or internal tyre structure is damaged. Visible cords, bulges, deep cuts, and repeated nearby repairs also increase replacement risk.
Can sidewall or shoulder punctures be repaired?
Sidewall or shoulder punctures are usually not repairable because these areas flex heavily when the vehicle moves. A repair in that area can fail under load, cornering, and heat. Replacement is usually the safer option.
Does driving on a flat tyre cause internal damage?
Driving on a flat tyre can crush the sidewall, overheat the rubber, damage the carcass, and destroy the inner liner. The tyre may still look repairable from the outside, but hidden internal damage can make repair unsafe.
Can previous repairs affect whether the tyre can be fixed again?
Previous repairs can affect the repair decision because a new puncture near an old repair can weaken the same tread area. A tyre technician checks spacing, repair type, tread depth, and internal condition before approving another repair.
Replacement Trigger Why Replacement Is Needed Recommended Action Nail or screw in sidewall Sidewall flex makes repair unsafe Replace the tyre Puncture near shoulder Repair area may not support a safe seal Ask a fitter to inspect the location Visible cord or ply Structural material may be exposed Stop driving and replace the tyre Tyre driven flat Internal sidewall damage may exist Request tyre removal and internal inspection Bulge or deep cut Structural integrity may be compromised Replace the tyre before further use
What is the difference between a plug, patch, patch-plug and sealant?
A plug, patch, patch-plug, and sealant all deal with punctures differently. External plugs and sealants are usually temporary solutions, while a professional internal repair checks and seals the tyre more safely. The correct method depends on location, size, angle, and internal tyre condition.
Is a tyre plug a permanent repair?
A tyre plug is not usually the safest permanent repair when fitted from the outside only. An external plug can close the visible hole, but it cannot confirm whether the tyre has internal damage. A professional inspection checks the inside of the tyre before any long-term repair decision.
Is tyre sealant safe for a nail or screw puncture?
Tyre sealant can help a vehicle move temporarily after a small puncture, but it should not replace a proper repair decision. Sealant may help you reach a safe repair point, but the tyre still needs inspection, especially when the puncture was caused by a nail or screw.
Why is a professional patch-plug repair safer?
A professional patch-plug repair is safer because the tyre is inspected from inside, the puncture channel is prepared, and the inner liner is sealed properly. This method gives the fitter a better view of hidden damage than an outside-only repair.
Repair Method Temporary or Permanent Best Use Limitation External plug Temporary in many cases Emergency tread puncture mobility Internal damage remains unchecked Patch Professional repair component Inner liner sealing May not seal the full puncture channel alone Patch-plug Professional repair method Eligible central tread punctures Requires tyre removal and inspection Sealant Temporary mobility aid Short-term movement to a garage May require later replacement or cleaning
How much does nail or screw tyre repair cost?
Nail or screw tyre repair cost depends on puncture location, damage size, tyre condition, repair method, and call-out requirement. A repairable tread puncture usually costs less than replacement, while sidewall damage or flat-tyre damage can require a new tyre.
What affects the price of puncture repair?
Repair price changes when the fitter needs mobile call-out, wheel removal, internal inspection, valve work, balancing, or replacement instead of repair. Tyre size, speed rating, load index, and vehicle type also affect replacement cost.
When is tyre replacement more expensive than puncture repair?
Tyre replacement is more expensive when the tyre cannot receive a safe repair because the damage is near the sidewall, the hole is too large, or the tyre has been driven flat. Replacement cost also changes by tyre brand, size, and fitting location.
Cost Factor Why It Changes Price What to Confirm Before Booking Puncture location Sidewall damage often requires replacement Ask whether repair is possible before approving work Repair method Professional repair needs inspection and wheel work Ask whether the tyre will be removed from the wheel Mobile call-out Roadside or home service adds travel time Ask whether call-out is included in the quote Replacement tyre Brand, size, and rating affect the final price Ask for tyre size and fitted price together
When should you call a mobile tyre fitter?
You should call a mobile tyre fitter when the tyre is losing pressure, the vehicle is unsafe to drive, the nail or screw is near the sidewall, or the tyre has gone flat. Mobile help reduces the need to drive on a damaged tyre.
When is mobile tyre repair better than driving to a garage?
Mobile tyre repair is better when pressure drops quickly, the car is parked at home or work, the tyre is flat, or the route to a garage requires fast roads. A mobile fitter can inspect the tyre where the vehicle is parked.
What details should you give the tyre fitter?
Give the fitter the tyre size, vehicle make and model, object location, pressure reading, sidewall condition, and whether the tyre has been driven flat. A clear photo of the nail or screw helps the fitter prepare for repair or replacement.
Situation Why Mobile Fitting Helps Information to Provide Tyre losing pressure Driving may worsen internal damage Pressure reading and leak speed Flat tyre Vehicle should not be driven Tyre size and vehicle location Object near sidewall Replacement may be required Photo of puncture position Roadside tyre issue Roadside movement may be unsafe Road name, postcode, and safety status
Need help with a nail or screw in your tyre? Book mobile tyre fitting if the tyre is flat, pressure is dropping, or replacement may be needed at home, work, or roadside.
What questions do drivers ask about a nail or screw in tyre?
Can you repair a tyre with a nail in it?
Yes, a tyre with a nail in it can be repaired when the puncture is in the central tread, the hole is within the safe repair limit, and the tyre has no internal damage. A nail in the sidewall or shoulder usually means replacement. A tyre technician must inspect the puncture before approving repair.
Can you repair a tyre with a screw in it?
Yes, a tyre with a screw in it can be repaired when the screw has caused a small, clean puncture in the repairable tread area. A screw can create a deeper or wider puncture than a short nail, so the fitter must check location, size, and internal damage.
Is it OK to drive with a nail or screw in tyre?
No, normal driving with a nail or screw in the tyre is not recommended because the puncture can worsen and pressure can drop. A short, cautious drive to a nearby tyre fitter may be possible when pressure stays stable, but motorway driving or long-distance driving should be avoided.
Should I leave the screw in the tyre?
Yes, you should usually leave the screw in the tyre until a professional inspection. The screw may be partly sealing the puncture channel. Removing it can cause faster air loss and leave the vehicle unsafe to drive.
How long can you drive on a tyre with a nail in it?
No fixed safe time exists for driving on a tyre with a nail in it. Pressure loss, puncture depth, speed, vehicle load, and tyre condition all change the risk. A tyre losing pressure should not be used for daily driving, long journeys, or motorway travel.
Will a screw in the tyre fail an MOT?
A screw in the tyre can contribute to an MOT failure if the damage affects tyre structure, exposes ply or cord, or leaves the tyre unsafe. A visible screw should be inspected before the MOT because repairability depends on puncture location and tyre condition.
Can you drive on the motorway with a nail or screw in the tyre?
No, motorway driving with a nail or screw in the tyre is unsafe because high speed increases heat, pressure stress, and failure risk. A slow leak can become serious at motorway speed. Stop safely, check pressure, and use mobile tyre support if the tyre condition is uncertain.
What should you do if the tyre is not leaking?
You should still arrange an inspection when a nail or screw is in the tyre but the tyre is not leaking. Stable pressure can mean the object has not fully penetrated, or it may be temporarily sealing the hole. A pressure recheck and professional assessment confirm the safest next step.
Can a nail or screw in the sidewall be repaired?
No, a nail or screw in the sidewall is usually not repairable because the sidewall flexes while the vehicle moves. A repair in that area can fail under load and movement. Replacement is normally required when the puncture sits in the sidewall or shoulder.
How do you know if the tyre needs replacing?
A tyre needs replacing when the puncture is in the sidewall or shoulder, the hole is too large, the tyre has been driven flat, or internal damage is found. Visible cords, bulges, deep cuts, or repeated nearby repairs also increase replacement risk.
