A small tread puncture can leave you deciding between a tow, a spare tire, or a quick roadside seal. The Onfunlee 70PCS Tire Repair Nails kit is a compact screw-in plug set made for minor punctures in tubeless tires. It includes two plug sizes, a hand driver, and a storage box, so it is easier to carry than a full reamer-and-rope repair kit. Its main advantage is speed, but the repair should be treated as an emergency measure, not a substitute for an internal inspection and professional patch-plug repair.
Quick Verdict
Rating: 8/10, recommended with safety caveats
Best For: Drivers and riders who want a compact emergency option for a small puncture in the central tread of a tubeless tire.
Bottom Line: The two plug sizes and simple hand driver make this kit quick to store and use. The tradeoff is that an outside-in screw plug cannot inspect or permanently repair hidden tire damage.

What Is the Onfunlee 70PCS Tire Repair Nails Kit?
The Onfunlee AU230915 is a compact set of self-tapping repair screws. Each piece combines a steel screw core with rubber sealing material. You use the supplied driver to place a matching plug into a small puncture after removing the nail or screw that caused the leak.
The set is a faster emergency option than a traditional rope-plug kit. It does not include a pressure gauge or inflator, so carry both. The box keeps the plug sizes organized.
Who Should Buy It?
Best For
- Drivers who want a compact backup for a small nail or screw puncture in tubeless tread.
- Motorcycle, ATV, or bicycle owners who have limited storage and already carry an inflator and gauge.
- Work or travel vehicles that need an emergency option while professional tire service is not immediately available.
Skip If
- You need a permanent, industry-standard passenger or light-truck tire repair.
- The damage is in the shoulder or sidewall, exceeds the plug range, or includes a cut, bulge, exposed cord, or torn tread.
- You do not carry a pressure gauge and inflator, or you cannot stop in a safe working location.
Before You Buy: A screw-in plug seals from the outside and does not let you inspect the inner liner or structural damage. The U.S. Tire Manufacturers Association states that a permanent passenger or light-truck tire repair requires tire removal, internal inspection, a stem to fill the injury, and a patch to seal the inner liner.
Feature-by-Feature Review
Plug Sizes and Puncture Coverage
The kit includes 35 plugs measuring 5.1 × 13 mm and 35 plugs measuring 6.7 × 15 mm. Seller listings pair the smaller size with 1 to 3 mm holes and the larger size with 3 to 5 mm holes. Having two sizes gives you a closer match than a one-size kit, but it does not make every puncture repairable.
Location matters more than plug size. Use should be limited to a small, straight puncture in the central tread area. A hole near the shoulder, an angled injury that reaches the belt edge, or any sidewall damage needs professional assessment rather than a larger screw plug.
Materials and Build
Each plug uses rubber around a steel screw core. The core gives the driver a firm grip, while the rubber is intended to seal the puncture path. Buyer feedback notes uneven rubber coverage on some pieces, so inspect each plug before use.
Do not use a plug with exposed, split, dried, or poorly centered rubber. A damaged plug may fail to seal evenly, and a sharp exposed section could create another problem instead of solving the first one.
Installation and Ease of Use
The hand driver is the kit’s simplest feature. You do not have to thread a sticky rope through an insertion fork, which can make emergency use less messy.
The kit does not include everything needed to finish the job. You still need a pressure gauge, an inflator or pump, a way to locate leaks, and the vehicle manufacturer’s recommended cold tire pressure. Gloves, wheel chocks, and a flashlight also make roadside use safer.
Storage and Portability
The box fits a trunk, saddlebag, ATV tool box, or workshop drawer. Store it closed in a clean, dry compartment away from sunlight, heat, fuel, and solvents that can age rubber.
Seal Reliability
For a clean, small puncture, the plug may slow or stop air loss long enough to reach a safer place or tire shop. Do not drive if pressure keeps falling or the tire vibrates, pulls, or shows damage.
For passenger and light-truck tires, industry guidance does not accept an outside-in plug alone as a permanent repair. Michelin likewise advises removing the tire for inspection and using a combined patch-and-plug repair when the puncture qualifies.
How It Performs in Real Use
Small Passenger-Car Tread Puncture
This is the kit’s strongest scenario: a visible nail or screw has caused a slow leak in the middle of otherwise healthy tubeless tread, and you can park well away from traffic. The two sizes help you choose a closer fit, but you should check the pressure immediately and arrange an off-wheel inspection as soon as possible.
Motorcycle, Bicycle, or ATV Storage
The box takes less room than many traditional repair kits, which is helpful when storage is limited. However, vehicle and tire manufacturers may set different repair limits. A repaired motorcycle or bicycle tire can affect handling quickly, so follow the tire maker’s instructions and stop riding if pressure falls or the tire feels unstable.
Road Trips and Remote Travel
For remote travel, pair the kit with a charged inflator, gauge, leak solution, reflective vest, flashlight, and working spare. Use roadside assistance when the location or damage is unsafe.
Work Vehicles and Fleet Backup
For work vehicles, mark the repaired tire, record its pressure, and send it for professional evaluation before normal service.
How to Use It Correctly
- Move to a safe location. Stop on firm, level ground away from moving traffic. Turn on hazard lights, set the parking brake, and follow your vehicle’s roadside procedures.
- Inspect before touching the object. Do not attempt a plug if the tire has a sidewall or shoulder injury, bulge, exposed cords, major cut, or signs it was driven while flat.
- Match the plug to the puncture. Use the smaller or larger plug only within the seller-listed range and follow the product instructions. Do not enlarge a hole just to make a plug fit.
- Check the seal. Inflate only when it is safe to do so, use the door-jamb pressure specification for the vehicle, and look for bubbles with soapy water.
- Monitor and seek service. Recheck pressure before driving and again after a short interval. Arrange a professional off-wheel inspection and proper repair or replacement promptly.
Pro Tip: Store a marker with the kit and circle the puncture before removing the nail or screw. That makes the hole easier to find if the tread shifts or the leak becomes hard to see.
Compatibility and Safety
The listing covers several tubeless tire types, but that does not mean every tire is approved. Run-flat, motorcycle, bicycle, commercial, high-speed, and previously repaired tires may have special limits. Check the tire maker’s policy.
For passenger and light-truck tires, the U.S. Tire Manufacturers Association’s repair guidance limits repairable injuries to the tread area and says plug-only, on-wheel repairs are unacceptable as permanent repairs. Michelin’s tire-repair guidance also calls for tire removal, internal inspection, and a combined patch-and-plug repair for qualifying punctures.
Do not use this kit on a sidewall, shoulder, large gash, split tread, bulge, exposed cord, or tire that has been driven flat. Do not work beside moving traffic or place yourself under a vehicle supported only by a jack.
[Products Worth Considering]
Salior’s tire plug kit provides a fast, reliable self-service fix for punctured or leaking tires without the need for flaring tools. Choose the correct plug size, then screw the nail into the puncture using the included screwdriver for an enhanced seal. The set is durable and convenient for on-the-go maintenance across multiple vehicle types.
This tire sidewall puncture repair kit fixes flats fast without removing the tire, helping you get back on the road in minutes. It includes self-tapping repair nails, essential tools, gloves, and a portable storage bag for convenient roadside use. Designed for tubeless tires, it helps create a tight, leak-resistant seal for cars, motorcycles, trucks, SUVs, and ATVs.
What Buyers Say
The supplied review summary is positive about the simple driver, compact box, and two plug sizes. Buyers describe it as easy to carry for a small emergency repair.
The most useful criticism is consistency. Some plugs reportedly have uneven rubber coverage or stick together in storage, and some users have seen slow air loss over time. Those comments support using the kit as a short-term backup rather than assuming every seal will last.
Pros and Cons
Pros
- Includes 70 plugs split evenly between two practical sizes.
- Simple hand-driver design avoids a separate reamer and insertion fork.
- Compact box is easy to carry in a vehicle or small tool compartment.
- Rubber-and-steel construction gives each plug a firm screw core and sealing layer.
- Useful as an emergency backup for a qualifying minor tread puncture.
Cons
- Not an industry-approved permanent repair for passenger or light-truck tires.
- Does not include an inflator, pressure gauge, or internal patch.
- Plug quality may vary, and the kit cannot address sidewall, shoulder, large, or hidden internal damage.
Is It Worth the Price?
The Onfunlee kit sits in the budget emergency-tool category. Its value comes from quantity and compactness: you receive 70 plugs in two sizes instead of a small handful, and the driver and box are included. That can make sense for a household with several tubeless-tire vehicles or a work kit that needs spare pieces.
It is not the best value if you expect a complete repair station. You still need an inflator and gauge, and a qualifying passenger or light-truck tire needs professional inspection and an internal patch-plug repair for long-term service. Buy it for emergency convenience, not as a replacement for proper tire service.
How It Compares to Alternatives
A reamer-and-rope kit takes more effort but prepares and fills the puncture channel. A sealant-and-inflator kit may be faster, though sealant can complicate later service and may have tire or sensor limits.
A working spare tire or roadside assistance remains the better choice for unsafe locations, sidewall damage, rapid pressure loss, or uncertain tire condition. The Onfunlee kit makes the most sense when storage space is limited and you want a simple backup for a small, visible tread puncture.
Why Customers Choose It
Buyers choose it for the compact box, simple driver, and 35-small plus 35-large size split. It is most useful during a slow leak when you also have the tools to verify pressure.
Frequently Asked Questions
Is the Onfunlee screw plug a permanent tire repair?
No. Treat it as an emergency outside-in seal. For passenger and light-truck tires, industry guidance calls for removing the tire, inspecting the inside, filling the injury, and sealing the inner liner with a patch.
What puncture sizes do the two plugs cover?
Seller listings identify the 5.1 × 13 mm plug for holes from 1 to 3 mm and the 6.7 × 15 mm plug for holes from 3 to 5 mm. Size alone does not determine repairability, because the location and internal condition of the tire also matter.
Can you use these plugs on a sidewall or shoulder?
No. Sidewall and shoulder injuries are outside the normal repairable tread area and can involve structural damage. Use a spare or roadside assistance and have the tire inspected for replacement.
Does the kit include everything needed?
It includes 70 plugs, a hand driver, and a storage box. You still need an accurate pressure gauge, an inflator or pump, and a safe way to check for continuing leaks.
Will it work on motorcycle, bicycle, or ATV tires?
The product is listed for several tubeless tire types, including motorcycles, bicycles, and ATVs. Repair policies vary, so check the tire and vehicle manufacturer’s instructions and do not continue if pressure or handling changes.
What should you check after installing a plug?
Set pressure to the vehicle specification, look for bubbles with soapy water, and monitor pressure closely. Stop driving if the leak continues, the tire feels unstable, or any bulge, vibration, pull, or visible damage appears.
How should the kit be stored?
Keep the plugs in the closed box in a clean, dry compartment away from direct sunlight, high heat, fuel, oil, and solvents. Inspect the rubber before a trip and replace any plug that is split, dried, stuck together, or unevenly covered.
Who should skip this kit?
Skip it if you want a permanent repair, lack an inflator and gauge, or cannot safely identify a small central-tread puncture. It is also unsuitable for sidewall damage, large cuts, damaged cords, bulges, or a tire driven while flat.
The Bottom Line
The Onfunlee 70PCS Tire Repair Nails kit is worth considering when you want a compact emergency option with two plug sizes and a simple driver. It suits prepared drivers and riders who understand that the seal is temporary; skip it for structural damage, rapid air loss, or any situation that needs a complete professional repair.
Its main strength is fast, tidy storage and setup. Its main limitation is that an outside-in plug cannot reveal or repair hidden internal damage.
