INJORA Silicone Rubber Inserts Foam for 106-108mm 1.9-inch Tires – Blue

Overview

INJORA silicone rubber inserts foam are designed for 1.9 inch tires, sized to fit outer diameters of 106–108 mm and a width around 36 mm. Finished in a vibrant blue, these inserts slide into the tire to create a compact, controlled core that helps maintain a consistent shape during use. Built for repeatable performance, the silicone material offers a different balance of stiffness and memory compared with standard foam, helping your RC rig respond predictably in tight turns and over rough terrain.

Materials and resilience

Crafted from silicone rubber, these inserts deliver waterproofing and temperature tolerance that helps performance stay steady across outdoor conditions. The blue color provides a visible reference during setup and field use, making it easier to monitor tire behavior in flight or on the ground.

Key benefits

• Waterproof and temperature resistant design keeps performance consistent in varied environments.
• Each insert weighs about 53 g, delivering a subtle counterweight that can contribute to steadier landings and reduced wobble.
• Stronger sidewall support helps tires retain their shape under load, supporting more predictable steering.
• Enhanced traction and grip help your rig respond confidently on rough, slippery, or uneven surfaces.
• Precise fit for 106–108 mm outer diameter and around 36 mm width ensures compatibility with select 1.9 inch tires.

Performance in real use

In practice, the silicone core can influence how the tire behaves when the rig is pushed hard. The combination of material stiffness and a modest weight adds stability during transitions and on irregular ground, which can translate to more consistent handling in challenging courses.

• Ideal for 1.9 inch tires when you want a stable, predictable ride.
• Supportive at high speeds, especially through corners and over rough terrain.
