Tannus Airless Questions

What are Tannus Airless Tires?

Tannus Airless Tires are made of a patented material called Aither. It’s a high quality foam-like polymer that allows them to be completely solid but ride like normal bike tires.

Why get Airless Tires?

You will never get a flat tire again.

Are they and insert?

Tannus Tires are not insert. They are an actual tire. Do I need my own tire? Keep your wheelset but you won’t need your rim strip, tube or tire. If you want to order a complete wheelset with Tannus Tires already installed please click here.

How do they compare to a regular tire?

Unlike other solid tires, Tannus has made technological advances that make the tires lightweight, comfortable and durable. Most people don’t notice a difference when they switch except they don’t get flats or have to worry about psi.

Will they make me slower?

Tannus Airless Tires stop flats. While most people don't feel a difference when riding, some riders notice a decrease in speed up to 10%.

How long do they last?

While they can last longer they can last up to 5,000 miles.

What's the PSI?

Most of the tires come in three different densities: soft, regular, and hard. View Specifications

Which Hardness should I buy?

Some of our tires come with "Soft" options and some have "Hard" options. If the option is available for the size you're buying, we recommend riders over 200lbs going for the "Hard" compound, riders between 120lbs & 200lbs riding the "Regular" compound, and riders below 120lbs going for the "Soft" compound. If the tire you're looking for doesn't have a hardness option, don't sweat it! The difference is most notable on the road sizes.

Are they heavy?

The weight varies by size.View Specifications

Are they for off road?

Tannus Tires are for road. If you’re looking for an off road option check outTannus Armour.

Where can I buy them?

You can buy them through us but we also encourage you buying them through your local bike shop. View Tannus Dealers
