Picked up a screw on the M5? Tyre pressure light flashing on the school run? A puncture doesn’t have to mean a new tyre. If the damage is in the tread and within the limits set by Australian Standard AS 1973, the safest and cheapest fix is a proper internal repair — not a roadside aerosol or a cheap external plug.
At Hot Tyres in Riverwood, we repair punctured and flat tyres the way the standard requires: tyre off the rim, inspected inside and out, and sealed with a combination plug-patch. Most repairs are done while you wait, and we’ll tell you honestly if a tyre is past saving rather than patch something that shouldn’t be on the road.

Can your puncture actually be repaired?
This is the first thing we check, and it’s governed by AS 1973-1993, the Australian Standard for passenger-car and light-truck tyre repair. Not every puncture is repairable — and a workshop that patches one that isn’t is putting you at risk.
A puncture is repairable when all of these are true:
- The hole is in the tread — the part of the tyre that touches the road.
- It sits within the central 60–70% of the tread width (the “minor repair” zone).
- The hole is 6mm or smaller in diameter (roughly the size of a standard screw or nail).
- The tyre still has legal tread depth (above 1.5mm across the tread) and no other damage.
- The tyre hasn’t been driven flat or shredded.
A puncture is NOT repairable when:
- The damage is in the sidewall (the smooth side of the tyre) — never repairable, no exceptions.
- The damage is in the shoulder (the curved edge between tread and sidewall) — outside the safe repair zone under AS 1973.
- The hole is larger than 6mm, or there are multiple punctures close together.
- The tyre was driven on flat, causing internal heat damage to the casing.
- There’s already a previous repair near the same spot, or visible bulges, cracking or perished rubber.
If your tyre falls in the “not repairable” column, we’ll show you why and quote a replacement — we stock new tyres and quality second-hand tyres at the same Riverwood workshop, so you’re not stranded.
Why the sidewall is off-limits
The sidewall flexes thousands of times a minute as you drive. There’s no fabric belt there to hold a patch, so any repair will work loose and fail — often at speed. A sidewall puncture, a sidewall bulge, or a gash from a kerb or pothole always means a new tyre. This isn’t a Hot Tyres rule; it’s the Australian Standard, and it’s the same at every reputable tyre shop in Sydney.
Tyre plug vs patch vs plug-patch — what’s the difference?
This is where a lot of cheap “puncture repairs” go wrong. Here’s the plain-English version.
Tyre plug (string/rope plug)
A sticky plug pushed into the hole from the outside, usually without removing the tyre. It’s fast and it’s what most roadside kits and some quick-stop shops use. The problem: it doesn’t seal the inner liner, it can let moisture into the steel belts, and it isn’t compliant with AS 1973 as a permanent repair. Fine to limp home on — not something you should drive on for months.
Patch
A rubber patch applied to the inside of the tyre over the hole. It seals the inner liner properly but doesn’t fill the puncture channel itself, so water and road grime can still creep into the casing over time.
Plug-patch (combination repair) — what we use
A single unit with a plug that fills the puncture channel and a patch that seals the inside. The tyre comes off the rim, the injury is reamed and cleaned, the area is buffed and cemented, and the combination unit is installed and rolled down from the inside. This is the proper, AS 1973-compliant permanent repair — and it’s what we do on every repairable tread puncture at Hot Tyres.
| Outside plug | Inside patch | Plug-patch (our method) | |
|---|---|---|---|
| Tyre removed from rim | No | Yes | Yes |
| Seals the puncture channel | Partly | No | Yes |
| Seals the inner liner | No | Yes | Yes |
| AS 1973 permanent repair | No | Partial | Yes |
| Best for | Emergency limp-home only | — | Permanent fix |
Short version: ask whether your “puncture repair” comes off the rim. If it doesn’t, it’s a temporary plug, not a permanent fix.
How we repair a punctured tyre — and how long it takes
Most single-puncture repairs are done while you wait. Busy periods aside, you can usually drop in without an appointment.
- Locate & assess — we find the puncture, mark it, and confirm it’s in the repairable tread zone under AS 1973. If it’s sidewall or shoulder, we stop here and talk replacement.
- Demount — the tyre comes off the rim so we can inspect the inside of the casing for hidden damage (you can’t do this from the outside).
- Prep the injury — the puncture channel is reamed and cleaned, and the inner surface is buffed and cemented.
- Install the plug-patch — the combination unit is fitted from the inside and rolled down for a permanent seal.
- Refit, balance & inflate — the tyre goes back on the rim, we rebalance the wheel, set it to the correct pressure, and refit it to the car.
- Road-ready check — final pressure and torque check before you drive off.
The rebalance matters — a lot of “cheap” repairs skip it, and you end up with a steering-wheel wobble at 80–100km/h. We don’t.
What to do right now if you’ve got a flat
Get this right and you’ll save the tyre — get it wrong and you’ll turn an affordable repair into a new tyre.
- Don’t keep driving on a flat. Even a short distance flat (or near-flat) overheats the sidewall and destroys the casing — at that point even a tread puncture becomes unrepairable.
- Pull over somewhere safe and flat, off the traffic lane, and put your hazards on.
- Got a spare? Fit the spare (or space-saver) and bring the punctured tyre to us. Space-savers are typically limited to 80km/h — check the sticker on the wheel.
- Got a repair/inflator kit instead of a spare? Use it to get to us, but treat it as limp-home only — it’s a temporary seal, not a repair, and it can make a foam mess inside the tyre.
- Run-flat tyre? You can usually keep driving at reduced speed (commonly up to around 80km/h for a limited distance — check your handbook), but once a run-flat has been driven flat it has often run beyond its safe limit and may need replacing. We’ll inspect it and advise.
- No spare and can’t move? Call us on (02) 9533 6138 and we’ll talk you through the safest option.
Same-day tyre repair in Sydney
For a single puncture, just bring the car to our Riverwood workshop during opening hours — most repairs are turned around the same day, while you wait. We’re minutes from the M5 and easy to reach from across the St George and Canterbury-Bankstown area.
If it’s after hours, the fastest option is to fit your spare and bring the car in first thing. See all of our tyre services if you also need a replacement, fitting or balancing.
How much does a tyre puncture repair cost in Sydney?
A proper plug-patch repair at Hot Tyres is fixed-price and affordable — call (02) 9533 6138 for a quote. That covers locating the puncture, demounting, the combination plug-patch, and rebalancing the wheel.
It’s a fraction of the cost of a new tyre — which is exactly why it’s worth checking whether yours is repairable before you replace it. If it isn’t repairable, we’ll quote a new tyre or quality second-hand tyre at the same visit so you don’t make two trips.

Tyre repairs and your NSW rego (pink slip & blue slip)
Bald, damaged or improperly repaired tyres are a common reason vehicles fail an eSafety check (pink slip). If your tyre has a sidewall bulge, a dodgy external plug, or tread below the legal limit, it won’t pass.
We can sort the tyres and do the inspection in the one visit:
- Pink slip (eSafety check): required to renew registration on most NSW vehicles 5 years and older; valid for 6 months.
- Blue slip (AUVIS): for unregistered, interstate or previously written-off vehicles; a more comprehensive identity and design check, valid for 42 days. Hot Tyres is an AUVIS-authorised inspection station.
Frequently asked questions
Is it safe to drive on a repaired tyre?
Yes — provided the repair was done correctly. A tread puncture (6mm or smaller, in the central tread) repaired with an internal plug-patch to AS 1973 restores the tyre to safe, full-speed use. An external-only plug is a temporary, limp-home fix and shouldn’t be relied on long-term.
How much does a tyre puncture repair cost?
At Hot Tyres, puncture repairs are fixed-price and affordable — far cheaper than replacing the tyre. If the tyre can’t be safely repaired, we’ll quote a new or second-hand replacement at the same visit. Call (02) 9533 6138 for a quote.
Can you repair a sidewall puncture?
No — and neither can any reputable tyre shop. Sidewall damage (and damage to the shoulder) is not repairable under AS 1973, because there’s no belt to support a patch and the area flexes constantly. A sidewall puncture, bulge or gash always means a new tyre. We’ll confirm the location and show you why before recommending a replacement.
How long does a repaired tyre last?
A correct internal plug-patch repair is permanent — the tyre will safely last the rest of its normal tread life, as long as it’s been driven on and inflated properly since. The repair isn’t what wears out; the tread is.
How long does the repair take?
Most single-puncture repairs are done while you wait, including rebalancing the wheel. Busy periods aside, you can usually drop in without an appointment.
What’s the difference between a plug and a patch?
A plug fills the puncture from outside (quick but not a permanent seal); a patch seals the inside but not the channel. A plug-patch combines both and is the proper permanent repair — it’s what we use.
Can a slow leak be repaired?
Often, yes. A slow leak is usually a small tread puncture, a leaking valve, or a poor seal at the rim. We’ll find the cause (sometimes it’s just the valve, not the tyre) and fix it if it’s within the repairable zone.
Do you offer same-day tyre repair?
Yes — bring it to our Riverwood workshop during opening hours and we’ll usually turn it around the same day while you wait.
Do you repair run-flat tyres?
We inspect run-flats, but a run-flat that’s been driven flat has often exceeded its safe limit and needs replacing. Bring it in and we’ll assess it.
What should I do right now with a flat tyre?
Don’t drive on it. Pull over somewhere safe, fit your spare (max around 80km/h on a space-saver), and bring the punctured tyre to us — or call (02) 9533 6138 if you’re stuck.
