Key Features

• Super-Soft Compound Tyres — The tyres are manufactured from a specially formulated super-soft rubber compound designed to maximise grip on natural terrain, rock surfaces, and varied ground conditions encountered during trail crawling and rock crawling sessions. This soft compound bites into uneven surfaces far better than standard harder compounds, giving you significantly improved traction when climbing obstacles or navigating technical sections.
• Memory Foam Technology — Integrated memory foam within the tyre structure provides cushioning and shock absorption during impacts whilst maintaining consistent shape memory, ensuring the tyre returns to its original profile after compression. This technology helps prevent tyre deformation during extreme articulation and provides a more realistic, compliant ride characteristic that mimics full-size vehicle behaviour on rough terrain.
• 12mm Hex Fitment — These wheels feature industry-standard 12mm hex connection points that fit directly onto the drive shafts of most popular 1/10 scale rock crawlers including Traxxas TRX-4 models, Element RC Enduro range, FTX Outback range, and many other compatible vehicles. No adapters or modifications required — simply install and go.
• 1.9 Inch Scale Wheel Size — The 1.9-inch wheel diameter (approximately 120.5mm) represents the perfect balance for 1/10 scale crawlers, offering sufficient ground clearance and proportionate scaling to match contemporary trail truck and rock crawler body shells. This size has become the industry standard for serious scale crawling setups.
• Scale Appearance — Unlike basic practical wheels, the Rocko 1.9 features authentic scale styling that maintains the realistic appearance of your build. The wheels deliver genuine scale truck proportions that look right whether you're displaying your crawler at home or posting photos online.
• Sold as a Pair — Each package contains two complete pre-mounted wheel and tyre assemblies, giving you the flexibility to use them as a matching set or to mix and match with your existing wheels for varied terrain performance tuning.
• Front and Rear Compatibility — These wheels are suitable for installation on both front and rear axles, providing flexibility in your setup configuration and allowing you to dial in your vehicle's handling characteristics through different tyre choices fore and aft.
• 45.6mm Tyre Width — The specifically calculated tyre width of 45.6mm provides the optimal contact patch for rock crawling applications, balancing traction requirements with weight considerations and maintaining proper suspension geometry on your 1/10 scale chassis.

Technical Performance

The Fastrax Rocko 1.9 Mounted Scale Wheels are engineered to deliver genuine performance improvements for demanding rock crawling and trail driving applications. The super-soft rubber compound is significantly more compliant than standard hard-compound trail tyres, providing measurably improved grip on natural rock, gravel, mud, and varied natural terrain. This matters because when you're navigating technical obstacle courses or climbing steep inclines, marginal grip improvements translate directly into improved traction and the ability to traverse obstacles that would defeat harder compound tyres. The memory foam construction ensures that during extreme suspension articulation — the hallmark of technical rock crawling where wheels compress dramatically as the suspension extends — the tyre maintains structural integrity and returns to its intended shape. This prevents the permanent deformation and hardening that occurs with basic foam or solid tyres after prolonged use. The 1.9-inch wheel size, combined with the 45.6mm width specification, creates a purposefully engineered contact patch optimised for the suspension travel and weight distribution characteristics of 1/10 scale crawlers. The black finish is durable and resistant to weathering, so these wheels maintain their appearance through extended outdoor use. Build quality is assured through Fastrax's manufacturing processes and quality control protocols, ensuring consistent fitment and performance across the pair. Whether you're running a Traxxas TRX-4 Chevrolet K10 Cheyenne, an Element RC Enduro trail truck, or an FTX Outback Hi-Rock, these wheels will integrate seamlessly with your existing setup and deliver measurably improved crawling capability on challenging terrain.

Frequently Asked Questions

• What vehicles are these Fastrax crawler wheels compatible with? — These wheels are suitable for most 1/10 scale rock and trail vehicles. They feature 12mm hex fitment, which means they're compatible with Traxxas TRX-4 models in all variants, Element RC Enduro trail trucks including Ecto, Zuul, Sendero and Trailwalker models, FTX Outback Hi-Rock 4x4 RTR crawlers, and numerous other 1/10 scale crawlers using standard 12mm hex drive shafts. Check that your vehicle uses 12mm hex hubs before ordering.
• Are these wheels suitable for beginners? — Yes, absolutely. These wheels come pre-mounted and ready to install — simply swap them onto your vehicle's hex hubs with no assembly required. Whether you're a beginner just starting with your first 1/10 crawler or an experienced rock crawler builder, the straightforward installation and immediate performance benefits make them ideal. The improved grip they provide actually helps beginner drivers develop better vehicle control skills by providing more predictable traction.
• What makes the super-soft compound better than standard hard tyres? — Standard hard-compound crawler tyres prioritise durability and wear resistance, which means they sacrifice grip performance. The Fastrax Rocko tyres use a specially formulated super-soft rubber compound that bites into rough terrain much more aggressively, providing superior traction on rock, gravel, dirt, and natural surfaces. This softer compound does wear faster under high-speed bashing, but for technical rock crawling and trail driving — the intended use — the grip improvement is dramatic. The memory foam technology ensures the tyre maintains shape throughout the session.
• What is the wheel size and will they fit my vehicle? — The Rocko 1.9 wheels measure 120.5mm in diameter and 45.6mm in width. The critical fitment specification is the 12mm hex connection, which is the industry standard for most 1/10 scale crawlers. If your vehicle uses 12mm hex hubs, these will fit perfectly. Vehicles using 14mm or 17mm hex will require adapters, which are available separately.
• How do the memory foam technology and super-soft compound work together? — The memory foam provides internal cushioning and shock absorption whilst the super-soft rubber compound provides the external grip interface. Together, they create a tyre that compresses and absorbs impacts during obstacle negotiation, then returns to its original shape ready for the next obstacle. This combination is far superior to solid hard tyres that provide no compliance, or basic foam-filled tyres that compress permanently. The result is consistent traction throughout your crawling session.
• Can I use these wheels on front and rear? — Yes, the Rocko 1.9 wheels are rated for both front and rear installation. Many experienced crawlers use different compound tyres front and rear to tune their vehicle's handling characteristics and weight distribution. These wheels work excellently in any position on your rig.
• What vehicles are listed as compatible in the product specifications? — The wheels are specifically listed as compatible with Element RC Enduro models including the Ecto, Zuul, Sendero, Trailwalker and Knightwalker, Traxxas TRX-4 in multiple variants including Chevrolet K10 Cheyenne, Ford F-150 Ranger, Chevy Blazer, Nissan Pathfinder and Bronco models, and the FTX Outback Hi-Rock. If you own any of these models, fitment is guaranteed.
