Tannus Armour Tire Insert – Puncture-Proof

Widely adopted by professional MTB teams, this insert targets thorn punctures and goatheads while reducing pinch flats. Installation is tool-free and straightforward, making it suitable for gravel, fat, and some E-bikes depending on tire size.
CushCore Pro Set
The CushCore Pro Set includes a tire insert, a Presta valve, and a rim sticker, providing a complete at-home installation option. It adds a protective layer around rims to absorb big impacts, reducing rim damage during aggressive maneuvers. The kit accommodates 2.1″–2.6″ tires and includes a tubeless valve, which helps air flow past the insert, improving overall ride smoothness and sealing performance. This system is ideal for riders seeking improved control on rough descents.

Suitable for various mountain bike configurations where tubeless setups are common, it emphasizes simple, tool-free installation and durable performance.
Buying Guide: Key Purchase Considerations
- Ride type and terrain: Gravel, MTB, fat bikes, and E-bikes demand different insert densities and thicknesses. For aggressive descents or thorn-prone routes, higher puncture resistance and rim protection are advantageous.
- Tire compatibility: Check tire width ranges for each insert. Some sets are tailored to 2.1″–2.6″ rims, while others support wider 4.0″ fat tires. Confirm wheel diameter (26″, 27.5″, 29″) and valve type (Presta vs Schrader).
- Weight and feel: Foam inserts add weight. Tubolight’s Diamana HD emphasizes minimal weight with strong protection, while heavier inserts may dampen harsh impacts more noticeably.
- Installation complexity: Some kits include valves and rim protection accessories, making at-home setup easier. If you’re new to tubeless systems, consider a CushCore kit for comprehensive rim protection and a guided install.
- Run-flat capability: Several products claim run-flat performance. This feature can help you finish a ride with a flat tire, but may impact rolling resistance and ride stiffness depending on formulation.
- Durability and recyclability: Look for products using durable polymer foams with recyclable options. This is relevant for riders seeking long-term sustainability and easy disposal at end of life.
- Warranty and team usage: Professional support and brand reliability can be indicators of long-term performance. Brands with pro team usage often reflect proven field results.
Overall, foam tire inserts offer a balance between puncture protection, rim safeguarding, and ride feel. When selecting among these options, prioritize compatibility with your bike type, preferred terrain, and installation preference. The right insert can reduce downtime and keep you riding longer between tire repairs.
