INJORA Silicone Rubber Insert for 118-122mm Tires - 4.75 OD, 1.9 Wheel (Large Blue)

INJORA Silicone Rubber Insert for 118-122mm Tires

Designed for RC crawlers with 1.9" wheels and 4.75" outer-diameter tires, the INJORA silicone rubber insert blends stability with lightweight feel. Built from silicone rubber, this insert is naturally waterproof and engineered to withstand temperature shifts you encounter on varied trails. The result is a component that stays consistent through mud, dust, and chilly mornings, while remaining flexible enough to cushion impacts without losing support.

Where standard foam can sag under load, this silicone insert adds robust sidewall support to help the tire keep its shape. That shape retention can translate into steadier steering, more predictable contact with uneven surfaces, and better control as you navigate tight turns or sudden changes in terrain. The combination of material and design aims to deliver a more confident ride without requiring you to change the overall tire setup.
