A tubeless tire insert is a foam component that installs inside a tubeless tire, between the tire casing and the rim. It dampens impacts, supports the tire during hard compressions, and helps protect the rim from damage, especially on rocky or technical terrain.

No. Tubeless inserts do not replace sealant.
Sealant is designed to seal small punctures, while inserts reduce pinch flats, rim strikes, and excessive tire collapse. Used together, they address different failure points in a tubeless system.

Tubeless systems reduce punctures, but they do not prevent rim damage or hard bottom-outs. Tubeless inserts add impact protection and tire stability, allowing riders to push harder, run lower pressures, and ride more aggressively with fewer mechanical issues.

No. When properly sized and installed, tubeless inserts dampen sharp impacts rather than increasing harshness. Most riders report improved control and reduced spike impacts, especially during high-speed or technical riding.

Yes, to a limited extent. Tannus Tubeless inserts provide ride-flat capability, meaning the insert can help support the tire and rim for short distances after air loss. This can allow riders to exit the trail without destroying the rim.

No. While downhill riders benefit significantly, trail, enduro, and aggressive XC riders also use inserts for rim protection, consistency, and confidence. Inserts are based more on terrain and riding style than bike category.

Tannus Tubeless Pro and Tannus Tubeless Fusion are tubeless tire inserts designed to dampen impacts, protect rims, and stabilize tire performance. The main difference is overall support level and post-impact ride feel.

• Tannus Tubeless Pro provides impact damping while maintaining a lively, responsive tire feel.
• Tannus Tubeless Fusion uses the same outer insert as Pro but adds a removable inner core for increased support, enhanced rim protection, and improved ride-flat capability.

Choose Tannus Tubeless Pro if you want rim protection and impact damping without significantly changing ride feel. It is ideal for trail and all-mountain riders who value responsiveness, efficiency, and controlled compliance.

Tannus Tubeless Fusion is ideal for aggressive riders, e-MTB and e-bike users, and high-impact terrain. It is designed to handle higher loads and repeated impacts while maximizing rim protection, tire support, and ride-flat capability.

Yes. Many riders run Tannus Tubeless Pro in the front tire for responsiveness and Tannus Tubeless Fusion in the rear for increased rim protection. This setup balances ride feel with durability.

Installing tubeless inserts is more involved than a standard tubeless setup but is manageable with basic tools and patience. Riders familiar with tubeless tire installation can typically install inserts without special equipment.

Yes. Sealant is required when using tubeless inserts. Sealant flows around the insert and functions normally to seal punctures. Use the recommended sealant volume for your tire size.

Usually, yes. Tubeless inserts allow riders to safely run slightly lower tire pressures, improving traction and control while reducing the risk of rim damage. Optimal pressure depends on rider weight, tire size, and terrain.
