Flat tires are just a part of automotive life. Some people experience them more than others, but almost all drivers will have to deal with a drive-ending puncture at some point. When this happens, a good tire repair kit is a great alternative to just swapping the deflated rubber for a spare tire or trying to run on tubeless tires. Some kits even make it easy to permanently fix the tire so you don't have to buy replacements. Check out our reviews and recommendations for the best tire repair kit.

Why Buy a Tire Repair Kit

  • Create a temporary tire fix. In most cases, tire repair kits are designed for a temporary fix, meaning the puncture repair should hold long enough to get the car to a garage for a permanent replacement. This makes a kit a good alternative to a traditional spare, especially when multiple tires are flat.
  • Save money on replacements. A puncture isn't necessarily the end of a tire. While larger holes tend to require an actual replacement, smaller punctures can be effectively sealed with the correct kit. When done right, the permanent fix can be more than enough to keep the tire running until normal wear warrants a replacement.
  • Learn a new skill. Tire repair isn't a skill just for drivers. Anything with rubber tires, from bikes to wheel barrels, can experience a flat. In most cases, the repair process is the same. This means the skills you learn by using a simple repair kit can be applied to different types of vehicles.

String Plug/Tire Patch

Repair kits that come with string plugs and tire patches make up the bulk of what's available on the market. A string plug is literally a piece of string that goes into the hole. Using a special insert tool, you can position the string so it’s soft body fills in the gaps and blocks air from escaping out of the tire. Tire patches work in a similar fashion by covering the entire span of the puncture. Both of these options tend to be very effective for larger punctures.

Tire Sealant

Using a liquid sealant, this type of repair kit is extremely user-friendly. The sealant is often designed to dry out of the bottle so it creates a physical barrier to block the hole. Most sealant formulas work well for smaller punctures.

Top Brands of Tire Repair Kits


Unlike some automotive accessory manufacturers, Slime is a company focused solely on tire repair. Well-known for its bike tire sealant products, Slime specializes in liquid tire repair using a liquid sealant that dries on contact with air. Beyond bike tires, the company makes a few options for automotive use like the Slime 1034-A Repair Kit.


As a company with a lot of experience in creating automotive parts, Smittybilt is no stranger to making products that are reliable and effective. While the bulk of the company's product line is centered around upgrade and offroading parts, the company also makes several accessories that are helpful to anyone driving on the road. The company's tire repair kit options include the 2733 Repair Kit.

Tire Repair Kit Pricing

  • $25 and under: Budget tire repair kits tend to be small and focused on the most important components needed to fix a flat. Typically, these include a few string plugs and a couple of T-handle tools to insert the plug into place without doing more damage to the tire.
  • $25-$50: Larger kits tend to make up the bulk of this price range. These kits come with either more string plugs or additional tools like hex keys, set screws, and pliers for different types of tires and repairs. 
  • $50 and above: Any kits above $50 tend to come with higher-quality components and additional accessories that can make tire repair quicker and easier. Air compressors, for example, are a common addition that often needs to be purchased separately with more affordable kits. 

Key Features


The most important part of any heavy-duty tire repair kit is the air safety seal itself. Plugs and liquid sealants are the most common types that can effectively handle small or medium punctures in a tire. The right choice will depend on the size of the puncture and the durability of the fix you need. Liquid sealant is a good temporary solution for anything really small, but larger punctures needing a more permanent fix are better served by string plugs.

Other Tools

To apply a sealer, specialty tools will be required. For string plugs, a basic insert tool (normally a T-handle needle-like tool) is needed to position the string into the hole to seal up any spaces where air could escape. A good set of pliers is also necessary to remove the source of the puncture. Higher-end kits often come with extra accessories like air compressors and a pressure gauge as well.


Multi-piece tire repair kits require a case to keep everything together. Basic plastic cases with molded interiors to keep each tool in place are very common. The price of the kit tends to reflect the quality of the case. Budget kits, for example, tend to have low-quality, flexible plastic cases that offer only basic protection.

Other Considerations

  • Size: The size of a tire repair kit depends on the number of included components or pieces. More pieces offer more versatility in general, but there is always the risk of having tools you will never use for a higher price. As a result, smaller kits are great to start with if you don't have a tire kit or much experience with one. Choose something larger only if you know you need the extra tools.

Best Tire Repair Kits Reviews & Recommendations 2020

This 56-piece kit from Boulder Tools gives you essentially everything you would need to repair a flat on a vehicle. With several different T-handles and plugs, the kit does a good job of offering a variety of items to fit the type of puncture you are fixing. The brown strings, in particular, are effective at handling different puncture sizes. 

The kit boasts a heavier build in some of the tools such as the included pliers and strings. Using thicker strings, the kit is geared more towards larger punctures that would normally send you into your local garage for replacement tires. With that said, the bulk of the strings may be too big for smaller punctures that are likely to create a slow leak.

The three main tools used to apply the strings all share the same high-quality construction. Unfortunately, the bulk of the kit is somewhat of overkill in most situations, and mismatched tools (i.e. metric hex keys and imperial set screws) are somewhat common. Finally, the case is rather large and may not fit in smaller car interiors or trunk spaces without taking over space. 

This is an affordable and compact tire emergency kit that can fix a flat tire or plug a puncture in any car, motorcycle, truck, or ATV tire. It comes with 22 pieces that are well-organized in a fabric zip case, so that you can squeeze it into a small storage compartment.

The kit consists of 15 pieces of self-vulcanized repair plugs, two tire valve stems, a four-way valve stem tool, an “L” hex key, a T-handle spiral probe tool, and a T-handle insert tool. You also get a jar of sealing lubricant, and the probing tool is sharp and can easily cut through tires. These tools are durable, rust-resistant, and are all you need to repair any tubeless tire.

Unfortunately, it doesn’t come with a pair of pliers or a blade, which can come in handy for pulling out sharp objects or trimming excess plug material, respectively. There have also been a few complaints that the T-handle tools can snap easily.

Slime's Power Spair repair kit embodies the company's multi-prong philosophy to tire repair. In addition to the typical string plug approach to blocking larger punctures, the kit also includes the company's Slime Tire Sealant that is designed to plug anything less than a quarter of an inch in size. The varied approaches make the kit suitable for a wide range of puncture sizes, including smaller holes that produce a slow leak that other kits typically can't handle.

The included slime is designed to make flat repair nearly instantaneous and automatic. The slime covers the puncture and hardens, creating a solid barrier that blocks air from escaping, much like normal tire plugs. Since the liquid has difficulty spanning punctures larger than a quarter of an inch, the included string plugs are a good backup.

The main drawback of the slime itself is the temporary nature of the repair. The resulting seal can break with enough force or in extreme temperatures. The included air compressor also makes it difficult to repair tires quickly, taking longer to fill up an average-sized tire than the higher-quality pumps that come with high-end kits.

The Blackjack KT-340 is one of the most expensive repair kits on our list, but that’s mainly because it’s an ideal kit for professionals. However, it’s also easy to use for beginners. It comes with high-grade tools that can help you permanently repair a tire and seal out moisture and dirt from the sealed puncture. With this kit, you can repair a puncture that’s as small as 0.2 inches in diameter.

The kit includes two T-bone handles, a screwdriver with a reversible shaft, a valve core removing tool, a razor blade, a hex wrench, and a specially formulated lubricant. It also includes a spiral probe that not only enlarges the hole for the plug but also removes any dirt that can weaken the adhesive. In addition, it comes with 40 ultra-sticky plugs that can conform to the shape of the puncture for an airtight seal. The tools are stored in a compact case with an ergonomic handle and multiple loop attachments for the tools.

Besides the price, another downside is that it’s possible to pull the screwdriver out of its handle if you push it deep into the tire. Also, the spiral probe can break or bend when you push it into the sidewall of a new tire.

The Smittybilt kit is one of the best car emergency kits due to its carefully thought-out components. The kit includes a pair of nose pliers, 30 self-vulcanizing plugs, a folding knife, interior tire patches, a reamer tool, an insertion tool, extra valve stems, and a lubricant. These tools can be used to fix punctures and tears and replace damaged valves. You also get side wall bailing wire for fixing sidewall damages. In case you don’t know how to use any of the tools, you can rely on the illustrated instruction manual.

The manufacturer provides a heavy-duty, zipped fabric case with an open design where elastic straps hold most of the tools in place. It’s also relatively lightweight, and you can carry it with your luggage. What’s more, it comes with a dual-head tire pressure gauge, so you can always check your tire pressure and maintain it at the desired level.

Naturally, this kit also has a few flaws. First, you don’t get a spare insertion bit, and the one provided tends to break or bend easily. Also, the reamer is powder-coated and smooth, which shouldn't be the case for any tool designed to penetrate the surface of a tire.

The ARB tire repair kit fixes tire-related issues without you having to remove the tire from the wheel. It comes with a wide array of tools that are made from high-quality steel and are well-organized in a compact plastic molded case. The kit includes 40 pieces of repair cords, an insertion needle, a reamer tool, a pair of pliers, a blade, and a lubricant. All these tools help make quick and permanent repairs.

It has a tire gauge so that you can check and continue to monitor the pressure of the tire after you fix it. All the tools are fairly easy to use, and if you find yourself stuck, you can fall back on the instruction manual. Apart from that, you can use the kit on any tubeless tire, including tires on motorcycles and lawnmowers.


However, it’s a bit on the expensive side, and it doesn’t come with as many tools as the other repair kits within its price range. Also, the plastic case is of poor quality and cracks easily when dropped.

This is an elaborate kit that comes with 94 pieces made from high-quality material, including 50 repair strings and a pair of work gloves to protect your hands as you work. The tools are useful in repairing up to one-inch punctures, including ones caused by glass and rocks. Everything in the kit is designed to help you make a professional and longer-lasting tire repair—starting with the sturdy T-handle made from unbreakable steel to the tire repair strips made from durable rubber that won’t harden easily.

You also get a pair of solid pliers that help remove sharp objects lodged in the tire and a bottle of lubricant that you can use on the probing tools for quicker penetration. We are impressed that it also includes a tire pressure gauge, which you can use to maintain the recommended tire pressure for safe driving.

However, the written instructions that come with the kit are somewhat hard to understand, and you would be better off relying on the pictorial guide on the online listing. Also, the kit is quite heavy. Despite that, you can use it to repair punctures on cars, tractors, motorcycles, trailers, and lawnmowers.

This is a great tire repair and sealing kit for tubeless tires on smaller tires on motorcycles, ATVs, UTVs, wheelbarrows, and small tractors. The best part is that you don’t have to dismount the tire when repairing it. As with most repair kits, this one includes a probe tool, a reamer tool, a hex wrench, a retractable razor knife, and 15 mushroom plugs.

What’s unique about this kit is that it comes with carbon dioxide gas canisters with flexible adapters that will help you inflate a fully deflated tire. Since it's for repairing smaller tires, the tools are relatively smaller and come with a compact zip-lock bag.

The main downside is that the tools aren’t strong enough for repairing punctures on larger vehicles. It also doesn’t come with an air gauge or any tools that can help to remove a nail stuck in the tire.


  • Tire patches tend to offer a good balance between string plugs and liquid sealants in terms of effectiveness and user-friendliness. The main thing that influences how well a patch works is the adhesive (i.e. glue, rubber cement, etc) it uses to stick to the tire. Poor adhesives can allow air to escape, especially as the sticky part begins to wear off with use.
  • Inserting a string plug into a tire can take a bit of strength. If you can't gently force the string into place, get somebody weight over the plug if possible. Make sure you push it in slowly to get the proper position.
  • Practice makes perfect when using a string plug. If possible, try repairing some old tires ahead of time before you find yourself in an emergency roadside situation. 
  • Rotate the tire before you apply the sealant. Liquid sealants need gravity sometimes. They tend to work the best when the puncture is at the bottom of the tire where the liquid can pool up and solidify.  


Q. What tools do I need in a tire repair kit?

A. Insertion tools like a plugging tool or sealant bottle are generally required to apply the sealer to the puncture site. A pair of pliers is also important to remove whatever caused the puncture in the first place.

Q. What is the best flat tire repair solution?

A. Fixing a puncture with a plug and a patch tends to be the safest way to restore a tire. A tire plug kit is a great temporary fix, but unless you replace the tire when you get to your destination, a patch does a better job of getting a permanent seal over the hole.

Q. How long do car tire repairs last?

A. This depends on the type. Liquid sealants tend to last long enough to drive back home or to your destination after a flat. Plugs and patches, on the other hand, can last tens of thousands of miles when applied properly. Always periodically check the repair and the tire pressure gauge to make sure it continues to perform well.
