Tubeless Tyre Repair: A No-Nonsense Guide to Keeping Your Ride Rolling
The beauty of tubeless tyres? They're a game-changer for cyclists. Fewer flats, better grip, and that magical moment when sealant swoops in to save the day. But let’s not kid ourselves—no system is bulletproof. Every rider eventually meets the puncture that laughs in the face of sealant. When that day comes, having the right tools and know-how can mean the difference between riding on and walking home.
Your Tubeless Toolkit: The Essentials
If you’re rolling on tubeless, you need to be ready for when things go sideways. Here’s what should always be in your kit:
Tubeless Plugs and Tool: Think of these as the cavalry for small punctures.
Tyre Levers: When a stubborn tyre decides to cling to the rim like it’s auditioning for a romance novel.
Pump or CO₂ Inflator: Speed is your friend when reseating a tubeless tyre.
Sandpaper or Metal Abrasive: Perfect for prepping patches; it’s the unsung hero of tidy repairs.
Tubeless Patch Kit: Because not every hole is plug-friendly.
Needle and Thread: Yes, it’s extreme, but for big tears, you might need to play surgeon.
Spare Inner Tube: For those apocalyptic moments when nothing else will do.
Don’t just pack these tools—get familiar with them. A tubeless setup isn’t a “set it and forget it” deal. Regularly check your sealant levels, rim tape, and valves.
Fixing Tubeless Tyres: Step-by-Step Repairs
1. Plugging the Hole
When the inevitable hiss of escaping air hits, plugs are your first port of call.
Find the Leak: Either listen for the tell-tale hiss or look for the sealant’s dramatic exit.
Prep the Hole: Insert the plug tool gently to avoid making the problem worse.
Insert the Plug: Slide in the bacon strip or plug, leaving a bit poking out.
Reinflate: Pump it up, spin the wheel, and let gravity help sealant do its job.
Pro tip: Don’t trim the plug flush with the tyre. Let it stick out a little to hold firm under pressure.
2. Patching the Inside
When plugs can’t cut it, the next step is to patch the tyre from the inside.
Remove the Tyre: Deflate, unseat, and locate the damage.
Prep the Area: Clean and roughen the inside of the tyre with sandpaper.
Apply the Patch: Use vulcanising solution and press the patch down firmly. Let it cure completely before reassembly.
Done right, an internal patch can last the lifetime of the tyre.
3. Stitching and Booting Tears
Got a gash that makes your tyre look like it met a bear? It’s fixable—at least temporarily.
Stitching: Use strong thread (even dental floss) to sew the tear shut. A few criss-cross stitches can stabilise the casing enough to ride home.
Booting: Place a makeshift boot—think an old tube, a toothpaste tube, or even a £5 note—between the tyre and the tube to stop bulging.
Keep in mind, these are “get home” fixes, not permanent solutions. Replace the tyre as soon as you can.
When Tubeless Fails Completely
Sometimes, nothing works. You’re out of sealant, the plugs won’t hold, and patches aren’t sticking. What now? It’s time for plan B: throw in a spare tube.
Inspect the tyre for sharp debris before inserting the tube.
Pump up the tube to a safe pressure, avoiding pinch flats.
This isn’t ideal, but it’ll get you rolling again until you can sort out a proper fix.
Tubeless Tyre Maintenance: Prevention is Better Than Repair
Want to minimise mid-ride dramas? Stay on top of maintenance:
Refresh your sealant every few months—more often if you ride in hot or dry conditions.
Check your rim tape and valves regularly. Small tears or leaks can wreak havoc.
Replace tyres before they’re worn thin. If the tread’s gone or the casing looks fragile, it’s time to upgrade.
Final Thoughts
Tubeless tyres aren’t foolproof, but they’re as close as it gets in the cycling world.
