Having a flat bicycle tire is a surefire way to ruin anyone's day, but thankfully to the brand Tannus you can now purchase a virtually indestructible set of tire for your bike that are guaranteed to always stay inflated.
Tannus has uncovered a revolutionary solid block tire design that keeps the wheel indefinitely inflated, completely eliminating the need to change your tires. The tires never need to be inflated because they're actually solid blocks made from a polymer resin called Aither. The resin is essentially a spongey foam that cannot be penetrated by punctures or deflate thanks to its high rolling resistance and solid foundation. The tires are available in either soft, regular or hard firmnesses and come in a variety of shapes and sizes to fit any bike.
