Flat tires are a bummer, especially when all you want to do is go for a ride. Bike tires are different than car tires because they have tubes. The tube is the component that holds air, while the tire itself protects the tube from popping and provides extra grip and traction on the road. It’s best to have a few tubes on hand in case yours pops (and believe us, it will). Tiny tears due to debris in the road or otherwise can occur and cause your tube to deflate. Sometimes you can’t see the damage or the debris that burst your tube (and your bubble), with that in mind it’s good to have a few additional tubes so you’re never restricted from hitting the road.
