Common Causes of Bike Tire Punctures & How to Prevent Them

There’s a moment every rider dreads, that sudden jolt, followed by the sag of your bike tire beneath you, and the slow realization that your ride just went from flowy to flat. Whether you're out chasing a sunrise on your favorite trail or just commuting across town, flats never arrive at a good time. And while they might feel like an inevitable part of cycling, the truth is, most flats are preventable. Especially if you're running with the right gear.

Let’s talk about the most common causes of flat bicycle tires and how to keep riding with confidence and peace of mind.

The Usual Suspects: What’s Really Popping Your Tires?

1. Punctures from debris (glass, thorns, goatheads):

This one’s a classic. Whether it’s a shard of glass or metal on the pavement or a goathead thorn hiding in dry singletrack, debris is one of the top culprits for punctured bicycle tubes. Riders out west know the pain of goatheads all too well, they're like nature’s caltrops.

2. Pinch flats (“snake bites”):

You hit a curb or rock just a little too hard, and the tire compresses enough to pinch the inner tube between the rim and the ground. You’ll often see two tiny holes, like fangs, hence the nickname “Snake Bite” 

3. Worn tires or improperly installed tubes:

A tired tire is more susceptible to tears. Add in an inner tube that’s twisted, over-inflated, or under-inflated, and you’ve got a recipe for an early trail exit or you are carrying your bike on the city bus. 

4. Sharp edges inside the rim (or old rim tape):

Even your wheel can be the villain. Old or misaligned rim tape can expose sharp edges that slowly wear down your tube from the inside out. It's the devil within that can get ya at any time! 

5. Temperature changes and pressure shifts:

Especially common with electric bicycle tires and high-speed riders, drastic temperature swings can mess with your tire pressure, leading to unseated beads or weakened spots.

Ride More, Worry Less: How to Prevent Flats

Riders today have more options than ever when it comes to avoiding the flat tire blues. While no solution is perfect for every setup, here are some that work, especially when paired with the right product.

• Use a Quality Bike Tire Repair Kit (But Hope You Won’t Need It)

We’ve all had that moment, trailside, tire off, patch kit in hand, and fingers crossed. A good bicycle tire repair kit is essential, but ideally, it should live in your pack and stay untouched.

• Check Pressure Regularly (Especially for E-Bikes)

Electric bike tires tend to carry more weight and go faster. That makes them more vulnerable to damage if pressure isn’t dialed in. Regular checks and seasonal adjustments go a long way.

• Swap Worn Bicycle Tubes & Tires

If your tire’s worn thin or your inner tube looks like it belongs in a bike museum, it’s time to change it out. Learn how to change a bike tire properly, and you’ll thank yourself down the road (or trail).

The Real Game-Changer: Tannus Armour

Most of us started with tubes. Maybe you’ve switched to tubeless or experimented with airless bike tires at some point. But if you’re looking for flat-out peace of mind, without giving up the ride feel you love, Tannus Armour is the move.

Tannus Armour is more than just a liner, it’s a 360° fortress for your bike’s inner tube. It wraps completely around your tube, creating a buffer between sharp debris, rim impacts, and the tube itself. That means no pinch flats, no thorn tears, and no unexpected sidewall explosions. Think of it like a bike helmet for your inner tube.

The best part, Armour doesn’t just stop flats, it also cushions your ride, adds stability to your handling, and lets you run lower pressures without risking a blowout. No matter where you are riding, Armour’s got your back!

Got a Different Setup? Tannus Still Has You Covered

Tannus Tubeless Inserts are built for those who push their rides to the edge. If you’re charging down chunky descents, cornering hard, or riding at lower pressures for better traction, these inserts are a must for any tubeless tire. They give your tires added sidewall support, reduce the chances of burping air mid-ride, and shield your rims from harsh impacts. Even if your tire goes completely flat, Tubeless Inserts give you the structure to keep riding until you're back at the trailhead or the truck. It’s the ultimate backup plan. 

Tannus Airless Tires are the ultimate no-flat solution…literally no air, no worries. These are perfect for city riders, commuters, delivery cyclists, and bike share fleets where reliability is necessary.

For folks who just want to get on their bike and go, Airless Tires are peace of mind on two wheels.

Flat Tires Are Optional Now

You’re not riding bikes to become a professional at fixing flats, you’re riding to chase that feeling of speed, flow, and freedom. While other riders are dealing with tube changes and goathead extractions, you can keep rolling with confidence.
