Z-T0068

Overview

The RC4WD Interco IROK 1.7" Scale Tyres (Z-T0068) represent the latest evolution in scale RC tyre technology, bringing officially licensed Interco rubber to the thriving 1.7-inch wheel revolution. These premium scale tyres are engineered for serious RC enthusiasts in the UK who demand authentic performance across challenging terrain—whether you're tackling rocks, muddy trails, snowy conditions or demanding scale competition courses. If you're building a Trail Class 1 scale crawler or trail truck, these tyres deliver the grip, durability and realistic appearance that separates genuine scale builds from basic RC cars.

Developed as a collaboration between RC4WD and the legendary Interco Tyre Company, the IROK 1.7" represents a significant step forward in 1.7-inch scale tyre development. These are not basic hobby tyres—they're competition-grade rubber moulded in RC4WD's advanced X2SS super-soft, super-sticky compound, specifically formulated to provide exceptional traction on natural terrain whilst maintaining the authentic scale look that discerning RC trail builders demand. Whether you're an experienced scale crawler pilot or stepping up from smaller 1.55-inch setups, these tyres will transform your vehicle's performance and appearance on the trail.

For UK-based RC car enthusiasts looking to upgrade their scale crawler or trail truck, the IROK 1.7" tyres tick every box: they meet official Trail Class 1 specifications, they're backed by Interco's proven real-world tyre engineering heritage, and they deliver measurable performance improvements in grip, handling and durability. The reinforced sidewalls keep your setup stable even under serious compression on rocks and obstacles, whilst the X2SS compound maintains its sticky characteristics across a wider range of conditions than standard compounds.

Key Features

• Officially Licensed Interco Design — These tyres carry the authentic Interco branding and engineering expertise from one of the world's most respected real-world tyre manufacturers. This isn't a generic scale tyre; it's based on proven Interco tyre technology adapted specifically for RC scale use, meaning you're getting design principles tested across decades of real vehicle performance.
• Advanced X2SS Super-Soft, Super-Sticky Compound — RC4WD's proprietary X2SS rubber formulation delivers exceptional grip across rocks, mud, and snow whilst maintaining the right balance of durability for extended trail use. The soft compound bites aggressively into natural surfaces, whilst the sticky nature of the rubber creates genuine traction rather than relying on tread pattern alone.
• Reinforced Sidewall Construction — The strengthened sidewalls provide crucial structural support when your crawler compresses through obstacles, preventing sidewall flex and maintaining consistent handling even under extreme terrain conditions. This reinforcement means your tyres maintain their shape and performance through multiple runs without degradation.
• Trail Class 1 Competition Specification — These tyres meet all official specifications to run in Trail Class 1 scale competition, making them ideal for anyone serious about competitive scale crawling or trail driving events across the UK.
• Authentic Scale Appearance — The tread pattern and sidewall markings deliver genuine scale aesthetics that look correct on display and in photographs, supporting builds that prioritise visual authenticity alongside performance.
• Designed for 1.7-Inch Wheels — Purpose-engineered for RC4WD's 1.7-inch wheel range (such as the Z-W0124), these tyres mount easily and securely, ensuring consistent performance with minimal fitment issues. Whilst they may fit some 1.9-inch wheels, the 1.7-inch fitment is recommended for hassle-free installation and optimal performance.
• Foam Inserts Included — Each pair comes with foam inserts that provide the correct sidewall support, cushioning and damping characteristics for authentic scale handling. These inserts are essential for proper tyre function and are included in the box.
• Lightweight Construction — At just 2.9oz (82g) per tyre, these offer excellent weight savings without compromising durability, making them perfect for vehicles where every gram counts in achieving proper weight distribution and handling characteristics.

Technical Performance

The RC4WD Interco IROK 1.7" tyres represent a significant advancement in scale tyre engineering for dedicated RC enthusiasts. Moulded in the advanced X2SS super-soft, super-sticky compound, these tyres are engineered to deliver measurable performance improvements across the full range of trail and crawler conditions. The compound formulation has been specifically developed to maintain grip and traction across temperature variations and surface types—from sharp rocky outcrops to slippery muddy terrain and snow—without sacrificing durability or wearing excessively with normal trail use. The reinforced sidewall construction adds structural rigidity that prevents the excessive flex that can compromise handling precision, particularly when navigating tight rocky sections or technical obstacles where consistent tyre response is essential. At 4.1 inches (104.3mm) outer diameter and 1.65 inches (42mm) width, these tyres provide a realistic scale proportion that suits 1/18 scale model trucks and crawlers, delivering authentic appearance alongside genuine functional performance. The 1.7-inch (43mm) inner diameter ensures precise fitment on dedicated 1.7-inch RC4WD wheels, though with careful installation they may work on certain 1.9-inch wheels from RC4WD's range. Each tyre weighs just 2.9oz (82g), making them lightweight enough for proper vehicle dynamics whilst maintaining the mass needed for realistic scale proportions. The inclusion of foam inserts is crucial to tyre performance—these provide essential sidewall support and cushioning that allows the soft compound to function correctly without collapsing under load, ensuring consistent handling characteristics across multiple runs and varying terrain.

Compatibility and Fitment

The IROK 1.7" tyres are specifically designed to fit RC4WD's 1.7-inch wheel range, with the Z-W0124 wheel being the primary recommended fitment. RC4WD has engineered perfect integration between their 1.7-inch wheels and these tyres, ensuring straightforward installation and optimal performance. Whilst these tyres may fit some RC4WD 1.9-inch wheels from their range, mounting can be challenging and requires careful installation technique. If you don't have prior experience mounting tyres to slightly larger wheels, RC4WD recommends using the dedicated 1.7-inch wheels to ensure reliable fitment and avoid potential mounting frustrations. Fitment with wheels from other RC manufacturers cannot be guaranteed due to design variations across the industry, so compatibility should be confirmed before purchase if you're intending to use wheels from non-RC4WD brands.
