Z-T0056

Overview

The RC4WD Interco IROK 1.55" Scale Tyres (Z-T0056) are officially licensed scale tyres that deliver exceptional performance for serious RC crawler enthusiasts across the UK. Whether you're tackling challenging rock crawls, muddy terrain, or snowy conditions, these tyres are engineered to provide the grip and durability you need for demanding off-road adventures. As an RC crawler owner, you'll appreciate that these tyres aren't just functional — they're authentically detailed replicas of the legendary full-size Interco IROK tyre, one of the most respected names in extreme off-road tyre engineering. This is a tyre that real-world 4x4 enthusiasts trust, and now RC4WD has brought that proven performance to the scale crawler market.

These scale tyres are specifically designed for 1.55" wheel diameter setups, making them the perfect choice for precision scale crawlers and rock buggies that demand realistic proportions and genuine off-road capability. The RC4WD Interco IROK represents a significant step forward in scale tyre technology for the UK RC community, combining authentic Interco branding with advanced compound formulations and thoughtful engineering details that separate premium scale tyres from basic alternatives. Whether you're a competitive crawler driver looking for maximum traction on rocks or a weekend enthusiast who values authenticity and performance, these tyres deliver on both fronts.

RC4WD is renowned for precision-engineered scale products that appeal to builders and drivers who refuse to compromise on detail or performance. The Interco IROK partnership brings together two industry leaders — RC4WD's expertise in scale RC engineering and Interco's legendary reputation in real-world extreme tyre design — resulting in a product that respects both the scale crawler community and the heritage of the original tyre.

Key Features

• Officially Licensed by Interco — These tyres carry the authentic Interco branding and licensing, meaning you're getting the real deal with genuine design heritage from one of the most respected tyre manufacturers in the world. This level of official licensing elevates your crawler from a toy to a true scale replica that respects the source material.
• Advanced X3 Soft Compound — RC4WD's proprietary X3 soft compound provides the grip and consistency you need across diverse terrain types, from rocky surfaces to mud and snow. The soft compound means better traction on uneven surfaces compared to harder tyre compounds, which translates to improved climbing ability and more predictable handling on technical courses.
• Inner Ribbing for Sidewall Support — Reinforced inner ribbing provides crucial sidewall support during aggressive off-road driving, preventing tyre roll and deformation when crawling over obstacles or navigating tight lines. This engineering detail extends tyre life and maintains consistent performance even during demanding driving sessions.
• Highly Detailed Scale Tread Pattern — The tread design isn't just functional; it's a faithful recreation of the full-size Interco IROK pattern, providing visual authenticity that scale purists demand. Detail-oriented builders and photographers will appreciate the accuracy of the tread sculpting when displaying their crawler or capturing action shots.
• Proven Performance Across Multiple Terrain Types — Real-world testing on rocks, mud, and snow demonstrates that these tyres aren't one-trick specialists. Whether you're running on a rock crawl course, through muddy woodland trails, or across snowy winter terrain, the X3 compound and tread design deliver consistent traction and handling characteristics.
• Foam Inserts Included — The package includes foam inserts that work with the tyres to provide cushioning and support, reducing shock transmissions to your scale crawler's chassis and helping maintain tyre shape under load. Quality foam inserts make the difference between tyres that perform consistently and those that degrade rapidly.

Technical Performance

The RC4WD Interco IROK 1.55" Scale Tyres are engineered for serious scale crawler applications where performance and authenticity matter equally. The outer diameter of 4.4 inches (111mm) with a 1.55-inch (39mm) inner diameter creates the correct proportions for 1.55-wheel setups common in precision scale crawler builds. The 1.72-inch (43.7mm) width provides adequate contact patch for genuine traction without compromising scale accuracy. At 3.25 ounces (92 grams) per tyre, the weight is carefully balanced to maintain proper vehicle dynamics without adding unnecessary mass that would affect suspension geometry and handling characteristics. The advanced X3 soft compound is specifically formulated to maintain grip across temperature variations and diverse surface conditions, a critical consideration for UK RC enthusiasts who might drive their crawlers throughout the year in varying weather. The inner ribbing construction prevents tyre roll and sidewall collapse — issues that can plague lesser-quality scale tyres during aggressive obstacle courses or when navigating tight radius lines. This construction methodology reflects RC4WD's commitment to engineering products that perform as authentically as they look. The inclusion of quality foam inserts ensures the tyres maintain their shape and performance characteristics, providing the cushioning necessary for smooth performance on unforgiving surfaces like rocks, concrete, and hardpacked earth. When combined with RC4WD 1.55-inch wheels, these tyres create a complete system engineered to work together; whilst compatibility with other manufacturers' wheels may be possible in some cases, RC4WD cannot guarantee fitment or performance with non-RC4WD products due to varying design methodologies across the industry.

• Will these tyres work with my current RC4WD wheels? — These 1.55-inch tyres are designed to fit RC4WD 1.55-inch wheels perfectly. If you already own RC4WD wheels in this size, fitment is guaranteed. For other manufacturers' wheels, fitment cannot be guaranteed due to variations in design specifications across different brands. Contact RC Model Shop if you need advice on wheel compatibility.
• How do the foam inserts improve performance? — The foam inserts provide cushioning that reduces shock transmission from rough terrain to your crawler's chassis, helping maintain consistent tyre shape and contact patch throughout a driving session. This results in more predictable handling, better grip maintenance, and extended tyre life compared to running tyres without proper inserts.
• Are these tyres suitable for competition rock crawling events? — Absolutely. The X3 soft compound and detailed tread pattern provide excellent traction on rocky surfaces, and the sidewall support via inner ribbing prevents tyre roll during aggressive technical climbing. Many UK scale crawler competitors trust Interco IROK tyres for demanding competition environments.
• What terrain do these tyres perform best on? — The X3 soft compound and tread design excel across multiple terrain types: rocks, mud, and snow all feature prominently in the proven performance profile. This makes the Interco IROK a versatile choice for UK drivers who may encounter varied conditions across different crawling locations and seasons.
