INJORA Silicone Rubber Insert Foam – 4 Pcs for 146-149mm (5.75-inch OD) 2.2 inch Tires (Green)

Overview

Enhance your RC tire setup with INJORA Silicone Rubber Insert Foam. Built to support the tire’s sidewalls and keep its shape under load, these inserts are crafted from silicone rubber to resist water and temperatures, making them a versatile addition to demanding terrain. Available in two hardness levels to suit different handling preferences, they’re designed for 146-149mm outer diameter tires with a 2.2 inch inner size, helping your rig tackle obstacles with confidence.

Two hardness options for tailored grip

• Green corresponds to a soft feel for responsive handling and compliant sidewall support.
• Blue corresponds to a medium feel for more steadiness and precise feedback during maneuvering.

The dual hardness choice lets you customize how the tire shape is maintained and how traction is delivered across varying surfaces. The inserts work to keep the tire profile consistent, which can translate to steadier cornering and more predictable steering response in real-world RC sessions.

Why choose silicone inserts for RC tires

• Enhanced sidewall support helps the tire maintain its intended shape, reducing squirm under load.
• Improved traction and grip can contribute to steadier climbs and better control in rough conditions.
• Waterproof construction and temperature resistance mean reliable performance across different weather and track conditions.
• Heavier weight offers a counterweight effect that may contribute to improved stability, especially on uneven terrain.

In practice, these inserts aim to balance compliance and support: you feel the tire conform to the surface while retaining enough rigidity to keep the wheel aligned and responsive. The result is a more controlled ride that suits both casual runs and more technical sessions, without promising guaranteed outcomes. Consider them a potential upgrade for riders seeking a configurable feel and additional tire stability.
