A nail in the tread on the way home, or a screw in a trailer tire at the job site, is the flat that a tire plug kit is made for. A spare gets you home, but a plug gets the tire holding air again without a shop visit. The best tire plugs for large holes are the screw-in plugs and heavy-duty strings that fill a bigger puncture and seal it against air loss. This guide compares plug kits by kit size, screw sizes, material, sealant and warranty, using only what each listing states.

How the picks were scored
Each kit is scored out of 10 on performance, build, value, safety and warranty. No kit here states a safety listing, so safety scores zero across the board.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.

Buying guide: choosing the best tire plugs for large holes
Screw-in plugs vs strings
Four kits here use screw-in rubber plugs, and one uses heavy-duty strings. A screw-in plug twists into the puncture and seals with its thread and rubber coating. The Slime strings are 4 in long and need no glue, for tubeless off-road tires such as ATVs, wheelbarrows, lawn mowers and trailers. Pick the type that matches the tire: screw plugs for road tires, strings for off-road tires, per the listings.
Size for the hole
Three kits come in more than one size. The MetFun kit has 10 small screws at 5.2×12 mm and 30 large screws at 6.6×15 mm. The RTTHEL kit has 33 small at 0.23×0.47 in, 33 medium at 0.25×0.55 in and 34 large at 0.27×0.59 in. The XTIFNDI kit states hole sizes: the small size repairs holes up to 1.2 mm in diameter, and the large size up to 1.5 mm. Match the plug size to the puncture, and check the sizes in the listing before ordering.
Sealant and the seal
Sealant helps the plug hold air. MetFun includes 2 tubes of sealant glue, and the plugs are pre-coated with sealing glue for a double seal. RTTHEL includes 2 tubes of sealant with pre-coated sealant and extra rubber. IHTHER plugs have a sealant-coated surface that bonds with the tire rubber. Slime strings need no glue. XTIFNDI states no sealant.
Kit size and spares
Kit sizes here run from 30 strings to 108 pieces. The RTTHEL kit holds 100 screws, 2 tubes of sealant, a screwdriver, 2 scrapers, 2 nozzles and a storage box, for 108 pieces. The IHTHER kit holds 60 screws plus a screwdriver and a case, for 61 pieces. The MetFun kit holds 40 screws and 2 tubes of sealant. A bigger kit keeps spares for the next flat.
Warranty
Two kits state a 1 Year warranty: XTIFNDI and IHTHER, which states a 1 Year Manufacturer warranty. RTTHEL states a 14 day warranty. MetFun states no warranty term, only to contact the seller for warranty information. Slime states no warranty term.
After the plug, air the tire back up with an automatic tire inflator.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.

- Check the plug type the tire needs: screw-in plugs for tubeless road tires, strings for tubeless off-road tires, per the listings.
- Match the plug size to the puncture: small, medium and large sizes are stated for three kits.
- Keep the kit in the trunk or toolbox: all five kits are sold as compact emergency kits.
- Check the sealant in the box: two kits include sealant tubes, one has sealant-coated plugs, and one needs no glue.
- Confirm the warranty in the listing: two state 1 Year, one states 14 days, and two state no term.
FAQ: garage tools
How does a tire plug work?
A screw-in plug twists into the puncture, and its thread and rubber coating grip the tire and seal the hole. MetFun states its plugs are pre-coated with sealing glue for a double seal, and IHTHER states a sealant-coated surface that bonds with the tire rubber.
How to use a tire plug?
Per the MetFun listing: remove the puncturing object, clean the area, apply the included sealant to the hole and screw, then screw it into the puncture. No need to take the tire off the rim, per the listing. IHTHER states to align the plug, twist clockwise with the included driver, and finish in under 10 seconds.
How long does a tire plug last?
No listing here states how long a plug lasts. The listings describe the seal as long-lasting and reliable, and Slime states its strings enable you to get to the nearest repair shop.
Can tire plugs fix large holes?
The kits here are sold for larger punctures. MetFun states its 30 large screws tackle larger ones, RTTHEL states its three sizes handle minor nail punctures, medium-sized holes and larger damages, and XTIFNDI states its large size repairs holes up to 1.5 mm in diameter. Match the plug size to the hole.
Do tire plugs need glue?
It depends on the kit. MetFun and RTTHEL include sealant tubes, IHTHER plugs are sealant-coated, and Slime states no glue is required for its strings. XTIFNDI states no sealant.
