Finding a screw in tire is a frustrating discovery for any driver. That glint of metal stuck in the rubber immediately raises questions and concerns, chief among them being whether you should yank it out right away. While the instinct might be to remove the offending object, doing so could actually make the situation worse. Understanding the potential consequences and the correct steps to take when dealing with a screw in tire is crucial for your safety and can save you from a bigger headache, like being stranded with a completely flat tire. This guide explores the best course of action.
Initial Assessment of the Screw in Tire
Before you make any decisions, the first step is to calmly assess the situation. Where the screw is located and how much air your tire has lost are key factors in determining what to do next. A quick inspection can provide valuable information about the severity of the puncture.
Identifying the Location of the Puncture
The location of the screw in tire is perhaps the most critical factor. Not all punctures are created equal, and where the screw has embedded itself dictates whether a safe tire repair is even possible. Take a close look at the tire’s surface.
Tread Puncture vs. Sidewall Puncture
A screw lodged in the main tread area – the part of the tire that contacts the road directly – is often repairable. This area is thicker and designed to withstand more punishment. Most professional tire repair shops can handle a tread puncture using industry-approved methods like a patch-plug combination, ensuring a safe and durable fix.
However, if you find the screw in tire located in the sidewall (the side face of the tire between the tread and the wheel rim) or the shoulder (the curved area where the tread meets the sidewall), the situation is different. This area experiences significant flexing and stress during driving. A puncture here compromises the tire’s structural integrity, making a safe, long-term repair virtually impossible. Attempting to fix a sidewall puncture poses a serious risk to driving safety.
Why Sidewall Damage Is More Serious?
The sidewall lacks the steel belts found in the tread area and is much thinner. It’s designed to flex constantly as the tire rotates and absorbs road imperfections. A puncture, even one plugged or patched, creates a weak spot that can fail catastrophically under stress, leading to a blowout and potential loss of vehicle control. For this reason, any sidewall puncture almost always necessitates a complete tire replacement for vehicle safety.
Checking Your Tire Pressure Immediately?
Once you’ve spotted the screw in tire, checking the air pressure is the next logical step. This tells you if you’re dealing with a slow leak or if the tire is rapidly deflating. Knowing the pressure helps you decide if you can drive cautiously to a repair shop or if you need immediate assistance.
Using a Tire Pressure Gauge
Don’t rely solely on visually inspecting the tire; a tire can lose significant pressure before it looks obviously flat. Use a reliable tire pressure gauge to get an accurate reading. Check the pressure in the affected tire and compare it to the manufacturer’s recommended pressure, usually found on a sticker in the driver’s side doorjamb, glove box, or fuel filler door.
Your vehicle might also be equipped with a Tire Pressure Monitoring System (TPMS), which should alert you with a dashboard warning light if a tire’s pressure drops significantly below the recommended level. However, a manual check with a gauge is always recommended for confirmation, especially if the puncture just occurred, as the TPMS might take some time to register the pressure drop, particularly with a very slow leak.
Understanding Slow Leaks vs. Rapid Deflation
Sometimes, the screw in tire acts like a temporary plug, significantly slowing down the rate of air loss. You might only have a very slow leak, losing just a few PSI (pounds per square inch) over several hours or even days. In this case, the tire might appear normal initially, and you might be tempted to ignore it or pull the screw out.
Conversely, the screw might have created a larger hole, or its angle might prevent it from sealing effectively, leading to rapid deflation. If the tire is losing air quickly or is already significantly low, pulling the screw out will almost certainly result in a completely flat tire very quickly. Leaving the screw in place, even with a slow leak, often buys you valuable time to get to a safe location or a repair facility.
The Big Question Pulling Out the Screw
So, should you pull the screw out? In almost all cases, the answer is no, not immediately. Leaving the screw in place is generally the safer option until you can get the tire properly assessed and repaired. The screw itself is often plugging the hole it created, preventing or slowing down air loss.
Removing it will likely open the puncture completely, causing the tire to deflate much faster. This could leave you stranded in an unsafe location or force you to change to a spare tire immediately, which might not always be feasible or safe depending on your surroundings and the condition of your spare. Keep the screw in the tire and focus on getting the vehicle to an auto shop.
What Happens if You Pull the Screw Out?
Giving in to the temptation to remove the screw can lead to several undesirable outcomes. While it might seem like the first step towards fixing the problem, it often creates more significant issues than leaving it untouched until you reach a professional.
Potential Consequences of Removal
Pulling out that foreign object might feel productive, but the risks associated usually outweigh any perceived benefit. Understanding these potential downsides reinforces why leaving the screw in the tire is typically the recommended course of action.
Rapid Air Loss and Stranding
The most immediate and likely consequence of pulling out a screw in tire is rapid air loss. As mentioned, the screw often acts as a plug. Removing it breaks that seal, and the air inside the tire, under pressure, will escape quickly through the open puncture. If the tire was holding some air, it will likely go flat within minutes, potentially leaving you stranded by the roadside.
This necessitates either changing to a spare tire immediately (if you have one and are in a safe place to do so) or calling for roadside assistance. It turns a manageable situation (driving slowly to a shop) into an immediate roadside emergency, increasing inconvenience and potential safety risks, especially on busy roads or in bad weather.
Making the Puncture Harder to Locate
Leaving the screw in place makes the puncture site obvious for you and, more importantly, for the mechanic performing the tire repair. Once the screw is removed, especially if the tire deflates completely, finding the small puncture hole again can sometimes be challenging, particularly if it’s small.
Technicians often submerge the inflated tire in water to look for bubbles, but having the screw still embedded pinpoints the exact location instantly, speeding up the assessment and repair process at the auto shop. Pulling it out might mean the technician has to spend extra time searching for the leak.
Possible Further Tire Damage?
Depending on the type of screw (especially if it has coarse threads or a sharp, jagged point) and how it’s embedded, yanking it out forcefully could potentially tear the rubber or damage the tire’s internal structure or belts around the puncture site. While often minor, there’s a slight risk of making the damage worse or enlarging the hole.
This could potentially turn a repairable puncture into one that is too large or complex to be safely fixed according to industry standards. It’s generally best to let a professional remove the object carefully as part of the controlled tire repair process.
When Might Removal Be Considered (With Caution)?
Are there any situations where pulling the screw out might be okay? Generally, it’s strongly advised against. The risks associated with premature removal usually outweigh any potential benefits. It’s almost always better to leave it in and drive cautiously, if possible, to a professional repair facility.
If you are already at a tire shop or have immediate access to tire repair tools (like a quality tire plug kit) and know how to use them properly, removing the screw would be the first step in the repair process itself. However, this assumes you are prepared to deal with immediate air loss and perform the repair right away. For the average driver discovering a screw in tire on the road, leaving it in is the standard recommendation.
Safe Steps to Take After Finding a Screw in Your Tire
Discovering a screw in tire requires a measured response. Avoid panic and follow a few simple steps to ensure your safety and maximize the chances of a successful, safe repair rather than needing a costly tire replacement.
Avoid Driving Long Distances or at High Speeds
Once you know there’s a screw in tire, even if the pressure seems okay, you should alter your driving immediately. Avoid driving further than necessary and keep your speed low, preferably below 45-50 mph. High speeds increase the stress on the tire and the heat generated, raising the risk of the puncture worsening or leading to a blowout.
Driving on a significantly underinflated tire, even for short distances, can cause irreversible damage to the tire’s internal structure, especially the sidewalls. This damage might not be visible externally but can compromise vehicle safety, potentially making the tire unrepairable even if the original puncture was in the tread. Your goal should be to get to the nearest reputable auto shop or a safe location to call for help as soon as possible.
Getting Professional Tire Repair Help?
Unless you are experienced and equipped for DIY tire repair, seeking professional help is the safest and most reliable solution for a screw in tire. Professionals have the tools and expertise to assess the damage correctly and perform a proper, lasting repair.
Visiting a Mechanic or Auto Shop
The best option is usually to drive cautiously (if the tire is holding sufficient air) to a trusted mechanic or a dedicated tire shop. They will remove the wheel, dismount the tire, and inspect the puncture from the inside – a crucial step often missed in DIY repairs. If the puncture is repairable (in the tread area, not too large, and no secondary damage), they will typically use a combination of a tire patch on the inside and a tire plug through the puncture channel.
This patch-plug method is considered the industry standard for a permanent and safe tire repair. The cost for this service is generally reasonable, often much less than the price of a new tire. The mechanic can also check for any internal damage caused by driving on low pressure.
Utilizing Roadside Assistance Services
If the tire is rapidly losing air, is already flat, or if you feel unsafe driving on it (especially if it’s a sidewall puncture), don’t risk it. Pull over to a safe location away from traffic and call for roadside assistance. Services like AAA or those included with many auto insurance policies can dispatch someone to help.
They can typically change the damaged tire with your spare tire, allowing you to then drive to a shop for repair or replacement. In some cases, the roadside technician might be able to perform a temporary tire plug on-site, but a follow-up professional inspection and permanent repair at an auto shop is still highly recommended.
Considering DIY Tire Repair Options
For those comfortable with basic automotive repair tasks, DIY options exist, but they come with caveats. These are often best considered temporary solutions to get you to a professional.
Using a Tire Plug Kit
A tire plug kit (from brands like Slime or Dynaplug) is a common tool for temporary DIY tire repair. These kits contain tools to ream the puncture hole and insert a sticky rubber plug to seal the leak. To use one, you would need to remove the screw, which, as discussed, will cause immediate air loss. You must be prepared to quickly ream the hole and insert the plug, then reinflate the tire using a portable compressor.
While a properly inserted plug can often stop a leak effectively, it’s generally considered a temporary fix. It doesn’t involve inspecting the tire’s interior for damage or applying an internal patch, which is part of a professional repair. If you use a tire plug, it’s wise to have the repair inspected and likely redone professionally at your earliest convenience for long-term driving safety.
Temporary Sealants (Like Fix-a-Flat)?
Aerosol tire sealants (like Fix-a-Flat) inject a sealant and propellant into the tire through the valve stem to coat the inside and plug the leak while also inflating the tire somewhat. While convenient in an emergency, these are generally less recommended for screw punctures compared to plugs.
The sealant can be messy, potentially interfere with the TPMS sensor inside the wheel, and make a subsequent professional repair more difficult (many shops charge extra to clean out the sealant). They are often seen as a last resort to get off the road, and the tire will still need professional attention immediately afterward. A plug kit is often a better temporary solution for a simple screw puncture.
Prevention and Long-Term Tire Care
While you can’t always avoid running over debris, practicing good tire maintenance and being mindful of road conditions can reduce the likelihood of encountering problems like a screw in tire and ensure overall vehicle safety.
Regular Tire Maintenance Checks
Making tire checks part of your routine car care can help you spot potential issues early. Regularly perform visual inspections of your tires, looking for embedded objects, cuts, bulges, or uneven wear. Check your tire pressure at least once a month (and before long trips) using a reliable gauge, ensuring they are inflated to the vehicle manufacturer’s recommendation.
Proper inflation not only improves safety and fuel economy but also helps tires wear more evenly and resist punctures better. Well-maintained tires are less susceptible to damage from road hazards.
Understanding When Tire Replacement is Necessary?
Even with diligent care, tires wear out and sometimes suffer irreparable damage. Know when a tire repair is not an option and tire replacement is required. This includes:
- Punctures in the sidewall or shoulder area.
- Punctures larger than 1/4 inch (6mm) in diameter in the tread area.
- Multiple punctures that are too close together.
- Damage caused by driving on a severely underinflated tire (internal structural damage).
- Tires worn down to the tread wear indicators (typically 2/32 of an inch).
- Tires showing signs of aging like cracking or bulging, regardless of tread depth.
Replacing tires when necessary is crucial for maintaining driving safety and optimal vehicle performance. Always replace tires in pairs (on the same axle) or as a full set of four for consistent handling, especially on all-wheel-drive vehicles.
Driving Habits to Minimize Puncture Risk
While you can’t dodge every hazard, being aware of your surroundings can help. Try to avoid driving through construction zones where screws, nails, and other sharp debris are common. Be cautious around industrial areas or recycling facilities.
Scan the road ahead for visible debris, especially after storms or accidents. Avoiding potholes and rough road surfaces when possible can also help preserve your tires. While finding a screw in tire can sometimes be unavoidable bad luck, attentive driving and good tire maintenance practices offer the best defense.
