Roadside repair
Two ways to seal a puncture, and the cement that makes both of them work.
A rasp and an inserter on 13.5 cm T-handles, a stack of 105 mm rubber strips, a set of screw-in rubber plugs, and tubes of rubber cement — the ingredient most cheap kits leave out. Ream the hole, wet the strip with cement, push it through, trim it flush. The wheel stays on the car and you are moving again in ten minutes.
Read this first: a plug is a get-you-home repair, not a permanent one.
The US tire industry is unambiguous about this. A proper repair means taking the tire off the rim, inspecting the inside for damage you cannot see from outside, filling the hole and sealing the innerliner with a patch. A strip or a plug pushed in from outside, on its own, is not an acceptable permanent repair — it is what gets you off the shoulder and to a tire shop, which is a genuinely useful thing at 9 p.m. on a Sunday.
The limits that come with it: tubeless tires only, tread area only — never a sidewall or a shoulder — and nothing bigger than 1/4 in (6 mm). A tire that has been driven on flat is damaged inside and does not get plugged at all.

What it fits
Car, motorcycle, bike — if the tire is tubeless
The method is the same on all three: the strip or the plug seals against the inside of the tire itself, with the wheel still on the vehicle. What decides whether it works is not what you are riding or driving — it is whether there is an inner tube in there.
Tubeless — nearly all modern car, light truck, RV, trailer and ATV tires, and most modern motorcycle tires — yes. Tube-type — most bicycles, older motorcycles, some trailers and mowers — no: the hole is in the tube, and the tube has to come out and be patched or replaced. Worth two minutes checking yours before you order.
The strip method
Five steps, and the reaming is the one that matters
1. Find the leak and mark it — soapy water in a spray bottle makes it obvious. 2. Pull the nail with the pliers, noting the angle it went in at. 3. Work the spiral rasp in and out along that same angle, half a dozen times. This is not optional: it cleans the hole and roughs the rubber so the strip can key into it.
4. Thread a strip through the eye of the inserter so both ends are even, smear it with cement, push it in until about two-thirds is inside, then pull the handle straight out — the strip stays. 5. Trim the ends flush, reinflate, and check it with soapy water again.
Why the cement matters
The tube most kits leave out
A strip can go in dry, and plenty of people do it that way. Cement does two things that make the job easier and the repair better: it lubricates a very tight push through cold tread, and it swells and bonds the strip to the hole as it cures instead of relying on friction alone.
Both sets include it — two 12 ml tubes in the 25-piece, four in the 57. Keep the tubes capped; once one has been opened and left, it skins over and the next repair is a dry one.
The other method
Screw-in plugs, for when there is no time to ream
The five black rubber cones in every set are the quicker, cruder option: smear one with cement, screw it into the hole by hand or with pliers, and cut it off level with the tread. No reaming, no threading a strip through an eye, and it works with cold hands in the dark.
A word on sizes: the maker’s chart shows two cones — 1.2 cm on a 0.5 cm shank and 1.5 cm on a 0.7 cm shank — but its own set photos show five identical cones, so we will not promise you get both. If the size decides it for you, ask us first. Same caveats as a strip either way: tread only, and get to a shop afterwards.
The sizes
Measured, and converted properly
Both T-handles are 13.5 cm (5.3 in) long and 8 cm (3.1 in) across the grip — short enough to live in a door pocket, long enough to get your weight behind. The strips are 105 mm (4.1 in). The pliers are 13 cm (5.1 in) and the knife 15 cm (5.9 in).
One note on the maker’s own chart, which is in the gallery: a few of its inch conversions are simply wrong — it prints the 15 cm knife as “15.90 in” and the 1.2 cm plug as “0.74 in”. The millimetre figures are the right ones, and the inches above are ours.
Straight answers
When not to use it
Never on a sidewall or a shoulder. That part of the tire flexes on every rotation and no repair holds there. If the damage is not in the tread, the tire is finished — that is not us being cautious, it is the industry rule.
Never on a tire that has been run flat. Driving on a deflated tire wrecks the innerliner and the sidewall from the inside, and none of that shows from outside. Plugging it hides a tire that is about to come apart.
Tubeless only — and that includes the bicycle in the maker’s pictures. A strip seals against the inside of a tubeless tire. Most bicycles, and plenty of older motorcycles and trailers, run an inner tube: there the tube is what is leaking, and it has to come out and be patched or replaced. Check before you buy this for a bike.
Not a substitute for a shop visit on a road car. Get it properly repaired — demounted, inspected, patch-plugged — or replaced. Many tire warranties treat an outside-only plug as an unrepaired tire.
No pump in any set. The strip seals the hole; it does not put the air back. You still need a compressor, a foot pump or a gas station.
Expect to push hard. Getting the rasp and a loaded inserter through cold tread takes real force, which is what the gloves in the 57-piece set are for. That effort is normal; it is not the tool failing.
The two sets
Exactly what is in each one
Counted off the maker’s own set photos, which are in the gallery. Both sets do the same repair with the same two T-handle tools, the same five screw-in plugs and the same zip case. The 25 is the one that lives in a glovebox; the 57 carries nearly three times the strips, twice the cement, and the hand tools you would otherwise be hunting for in the dark.

Doing it safely
Get off the road first. Well clear of moving traffic, hazards on, handbrake on, and the other wheels chocked if there is any slope. No repair is worth kneeling next to a live lane for.
Gloves on, and mind where the tools go when they break through. The rasp and the inserter come through the tread suddenly and both ends are sharp. Keep your other hand out of the line of travel.
Reinflate to the pressure on the door placard — the sticker in the driver’s door jamb, not the number moulded into the tire, which is a maximum. Then recheck the repair with soapy water, and check the pressure again the next morning.

Questions people ask
Before you order
Which set should I buy?
Both fix a puncture the same way, so it comes down to what else you want with it. Take the 25 if you already keep pliers, a knife and gloves in the car and you just want the repair gear. Take the 57 if the car has nothing in it — it adds those three, plus 40 strips instead of 15 and four tubes of cement instead of two, which is the difference between one roadside fix and a kit you keep topping up from.
How long does a plug last?
People report plugs holding for years, and that is exactly why they are risky: a repair you stop thinking about is one nobody ever inspected from the inside. Treat it as temporary, get the tire demounted, inspected and patch-plugged at a shop, and let them tell you whether it is still good.
Can I repair a sidewall with it?
No. Nobody can. The sidewall flexes on every rotation and there is no repair rated for it — that tire gets replaced.
How big a hole is too big?
Over 1/4 in (6 mm) in the tread is beyond repairable by any method. A nail or a screw is usually well under that; a bolt, a chunk of metal or a gash is not.
Strip or screw-in plug — which is better?
The strip, if you have the time and the hole is a clean nail puncture: it fills the channel along its whole length. The plug is faster and needs no reaming, which matters when it is raining. Both are temporary.
Will it work on my bicycle?
Only if your bike runs tubeless, which most do not. With an inner tube in there the tube is what has the hole in it, and no amount of plugging the tire will help. The maker’s images show a bicycle; we would rather you checked first.
Does it come with anything to reinflate the tire?
No. No pump, no compressor and no gauge in either set. The air has to come from somewhere else.
Do the strips go off?
They harden with heat and time. Keep them sealed and out of the sun; a kit that has lived on a parcel shelf through two summers will have strips that have gone stiff, and a stiff strip will not seal. The cement skins over once opened, too.
Can I do it without taking the wheel off?
Yes, that is the point of the kit — as long as you can reach the puncture. If it has stopped somewhere awkward behind a brake caliper, rolling the car forward a foot usually sorts it.
