When Weeds Attack: A Bike-Riding Parent’s Tale
It was a perfect Saturday morning. The desert sun had just started to warm the trails, and my son and I were ready for a ride. Five minutes in—and hisssss. Another flat. I picked up the culprit and sighed: goat heads again. Also known as puncturevine or devil’s thorns, these tiny seedpods have turned every trail ride into a gamble. If you bike in dry climates, you probably know exactly what I’m talking about. Here’s what these thorny troublemakers are, why they’re so effective at ruining your day, and what I did to finally protect my son’s tires from their wrath.
What Are Goat Heads (Besides Evil)?
Tiny Seeds, Big Problems
Goat heads, the common name for Tribulus terrestris, are sneaky little burrs that thrive in arid environments. These seeds are shaped like miniature caltrops—nature’s own tire spikes—designed to latch onto anything that moves. In dry, dusty regions like the American Southwest, they grow along sidewalks, trails, and roadsides. Each pod has multiple hard spines, and one is always pointing up, ready to strike.
Why They’re So Destructive
– Hard as Nails: The spines are tough enough to pierce rubber.
– Everywhere: They grow low and wide, dropping seeds like landmines.
– Multiple Spikes: Even if one doesn’t stick, another will.
Once they lodge into a bike tire, they often stay hidden until you hear that all-too-familiar hiss of escaping air.

The Flat Solution: Mountain Bike Tire Liners
How I Finally Beat the Thorns
After enough flats to fill a landfill, I turned to a simple, low-tech solution: Mountain Bike Tire Liners. These protective strips slide between your bike’s tire and inner tube, forming a barrier that stops thorns, nails, and sharp debris from causing punctures.
Why They Work
– Fits Most Wheel Sizes: Compatible with 24″, 26″, and 29″ tires.
– Simple Installation: Cut to size, slip it in, and ride.
– Dual Protection: Comes in pairs for both tires.
– One-Year Warranty: Peace of mind if you’re a frequent rider.
I installed them on my son’s bike in under 20 minutes. Since then? Not one flat. Not from goat heads, not from glass, not from anything.

Other Ways to Save Your Ride
Strategies Beyond Liners
Though tire liners are a game-changer, there are other ways to prevent flats:
– Tubeless Tires with Sealant: Helps seal small punctures automatically.
– Thorn-Resistant Tubes: Thicker tubes that resist puncture.
– Tire Slime: A gel that plugs holes as they form.
– Avoid Weed Zones: Stick to groomed trails or ride after rain when seeds are less likely to stick.
How effective are tire sealants in long-term use for riders in thorn-heavy terrains versus physical barriers like tire liners?
Final Thoughts: Stay Ahead of the Thorns
Goat heads may be small, but they’ve got a big impact—especially on mountain bikers in desert regions. They’ve sent my son walking home too many times. But with a simple tire liner and a few smart choices, we’re finally riding again without fear of flats. The desert may be harsh, but your tires don’t have to suffer for it.
