INJORA Silicone Rubber Inserts for 1.0" 56-58mm Tires (1056)

Product Overview

The INJORA Silicone Rubber Tire Inserts (1056) are precision-engineered foam replacements designed specifically for 1/24 and 1/18 scale RC crawler tires measuring 56-58mm outer diameter and 22-24mm width. These premium silicone inserts deliver superior sidewall support, waterproof performance, and temperature resistance that dramatically outperforms traditional open-cell foam inserts for serious micro crawler enthusiasts.

Available in two compound options—Yellow (Super Soft) and Green (Soft)—the INJORA 1056 Silicone Tire Inserts allow you to fine-tune your crawler's tire performance for different terrain conditions. The super soft yellow inserts maximize ground contact and conformability on technical rock sections, while the soft green inserts provide balanced support for mixed terrain including dirt, gravel, and moderate rock crawling.

Unlike conventional foam that absorbs water, compresses permanently, and degrades in extreme temperatures, the INJORA Silicone Rubber Inserts (1056) maintain consistent performance through mud, water crossings, and temperature extremes. Weighing just 11 grams per insert, these silicone tire supports preserve your tire's shape during extreme articulation while adding minimal rotating mass, ensuring your micro crawler maintains optimal traction and scale appearance on any terrain. Compatible with a wide range of INJORA 1.0-inch tires including the Rock Terrain (T1005), Swamp Stomper (T1015), King Trekker (T1017), and many more.

Key Features

• Premium silicone rubber construction — Delivers superior durability and consistent performance compared to traditional foam that degrades and compresses over time
• Waterproof design — Prevents water absorption that causes foam inserts to become heavy, soggy, and lose support during water crossings and wet conditions
• Temperature resistant materials — Maintains flexibility and support in extreme heat and cold where conventional foam becomes brittle or overly soft
• Enhanced sidewall support — Keeps tire shape consistent during extreme suspension articulation, preventing tire collapse and maintaining optimal contact patch
• Two compound options available — Yellow (Super Soft) for maximum conformability on rocks, Green (Soft) for balanced all-terrain performance
• Lightweight 11g per insert — Minimizes rotating mass while providing essential tire support for responsive handling and reduced drivetrain load
• 52mm × 18.8mm dimensions — Precision-sized to fit INJORA 1.0" tires measuring 56-58mm diameter and 22-24mm width
• Extensive INJORA tire compatibility — Confirmed fitment with Rock Terrain (T1005), Swamp Stomper (T1015), Crawler Tire (T1016), King Trekker (T1017), Swamp Claw (T1021), Mud Paw (T1023), HAMROK (T1027), and MAVERIX (T1028) tire models

Performance & Handling

The INJORA Silicone Rubber Tire Inserts (1056) transform your micro crawler's traction and handling by maintaining consistent tire shape and sidewall stiffness across all terrain types. Traditional open-cell foam inserts absorb water during creek crossings and wet grass, adding weight and losing support—the silicone construction eliminates this problem entirely, ensuring your tires perform identically whether dry or soaked.

The two-compound system lets you match insert firmness to your driving style and terrain. Yellow Super Soft inserts allow maximum tire deformation, creating larger contact patches on irregular rock surfaces and technical climbs where conformability is critical. Green Soft inserts provide slightly firmer support for mixed terrain driving on dirt, gravel, grass, and moderate rocks, preventing excessive tire squirm during high-speed sections while maintaining good articulation. Both compounds resist permanent compression, so your tires maintain their intended profile session after session without the sagging and flattening common with foam inserts.

Technical Systems

Silicone rubber's closed-cell molecular structure provides inherent waterproofing and temperature stability that open-cell foam cannot match. The material maintains consistent Shore hardness across a wide temperature range, ensuring predictable tire performance whether you're crawling in summer heat or winter cold. The 52mm × 18.8mm sizing is engineered to provide optimal fill within 56-58mm diameter tires, supporting the sidewall without overstuffing that can cause tire ballooning or bead unseating on beadlock wheels.

Compound Options

The INJORA Silicone Rubber Tire Inserts (1056) are available in two performance-tuned compounds:

• Yellow (Super Soft) — Maximum conformability for technical rock crawling, steep climbs, and competition courses where tire deformation and grip are paramount
• Green (Soft) — Balanced firmness for all-terrain driving, providing excellent support on mixed surfaces including dirt trails, gravel, grass, and moderate rock sections

Both compounds feature the same waterproof, temperature-resistant silicone construction and 11-gram weight per insert.

Why This Model Is a Good Choice

The INJORA Silicone Rubber Tire Inserts (1056) represent a significant performance upgrade over traditional foam inserts at a competitive price point. While foam inserts cost less initially, they require frequent replacement due to water absorption, compression, and temperature degradation—silicone inserts maintain their performance characteristics indefinitely, delivering better long-term value. The waterproof construction alone is worth the upgrade for crawlers who encounter wet conditions, eliminating the frustration of waterlogged tires that lose support and add unwanted weight. With two compound options available, you can fine-tune your tire performance for specific terrain without changing tires, and at just 11 grams per insert, you're adding essential support without the weight penalty that affects acceleration and battery life. The extensive compatibility with INJORA's 1.0-inch tire lineup—including eight confirmed tire models—ensures you can use these inserts across multiple tire sets as you experiment with different tread patterns and compounds. Whether you're running an SCX24, FCX24, TRX4M, or custom micro build with compatible 1.0" tires, the INJORA 1056 Silicone Inserts deliver professional-grade tire performance that serious crawlers demand.
