Biking is wonderful. Whether you ride for practical purposes or just to feel the wind in your hair (while possibly imagining you’re on a horse) it’s a good time. Getting a flat can ruin all of that. Check out Tannus Tires, the tires that will never go flat.

These tires are perfect for urban bikers who have to contend with nails, glass, and random pieces of scrap metal haphazardly thrown in the street. With these attached to your bike, you can be sure that no matter what the road throws at you, your tires will survive. The reason they don’t pop is simple, they’re solid.

They’re made from Micro Closed Cell Polymer Resin and looks quite like the stuff they make running shoes from. Despite being solid, they are lightweight tires that have the same feel as your normal everyday air tires. In fact, they may even be lighter. They come in 12 fashionable colors from basic black to red, green, purple, yellow, blue, white, brown, orange, pink, and gray. You can pick the one that matches your bike best. Tannus Tires are available from multiple shops around the world.
