July doesn't have one cause behind its flat tires. It has four, all stacking up at once: softer asphalt that holds onto debris, tube pressure that climbs as the pavement heats up, and more broken glass and goatheads left behind after holiday weekends. That's the real reason bike tires go flat more in summer than any other season, and most riders only ever hear about one piece of it.

This breaks down exactly what's happening to your tires this month, then shows what actually stops it. Tannus Armour is a foam liner that blocks debris before it ever reaches your tube, and Tannus Airless tires remove the tube and the air pressure altogether, so there's nothing left for the heat to work against.

Your commuter tires are supposed to be the last thing on your mind. The light changing two blocks up, the pothole on your usual route, whether you locked up in time, that's what fills a commuter's headspace. The tire is just supposed to work. 

City riding asks more from a tire than most people realize. Glass in the bike lane, wet metal grates, sun-softened asphalt, the specific hostility of a road that hasn't been repaved since 2019. Most commuters are rolling on whatever came stock with their bike, which means rolling on a compromise. This is what a commuter tire actually needs to do, and why riders in New York, Chicago, Seattle, and Portland are making the switch to airless.

Kyle Strait is the only rider to compete in nearly every Red Bull Rampage since 2001, and the only two-time winner in the event's history. For 2026, he's running Tannus bike tire inserts on both his e-bike and enduro rig. Tannus Armour for his tubed setup, and Tannus Tubeless Pro for his enduro build. He was running them before we even called him our athlete.

Bosch spent more than 30 years perfecting the mid-drive motor. This week, they put one in a hub. Here's why that matters for your city e-bike. And why the one thing that hasn't changed is the only thing that can ruin your day.

If you have been researching Tannus Armour, you have probably come across some different opinions about what it does, how it installs, and whether it is worth it. Most of that confusion comes from riders comparing completely different bikes, riding styles, and expectations.

Tannus Armour is built for one simple purpose: helping tube-based bikes prevent flats before they happen. That means commuters, e-bike riders, kids’ bikes, mountain bikes running tubes, city bikes, and everyday riders who are tired of dealing with punctures, pinch flats, and roadside tube changes.

Let’s walk through the biggest questions riders usually have before buying.
