Whether you are maintaining your existing setup or building a custom configuration, these Monster Truck wheels deliver the robustness and precision that ARRMA is recognised for across the RC community.
Designed specifically for 1/5 scale Monster Truck models, these wheels feature a substantial 4.9-inch overall diameter that provides excellent ground clearance and proportionate scaling. The 24mm hex fitment ensures compatibility with major ARRMA 1/5 scale models including the legendary Kraton 4X4 8S and Outcast 4X4 8S platforms. If you are shopping for Monster Truck wheels UK retailers stock, or looking for replacement wheels for your high-powered brushless RC vehicle, this product offers genuine ARRMA engineering in a convenient two-wheel package.
These wheels have earned a solid 4.2 out of 5 customer rating, reflecting their popularity amongst both weekend bashers and experienced RC competitors. The five-spoke design combines aesthetic appeal with functional strength, whilst the reinforced hub structure ensures longevity even under demanding off-road conditions. For anyone invested in serious RC hobby participation, having spare wheels or upgrading to higher-quality rolling stock is a crucial consideration that directly impacts performance and reliability.
Key Features
- Split Five-Spoke Design — The distinctive five-spoke configuration provides a perfect balance between structural strength and lightweight construction, reducing unsprung mass whilst maintaining the rigidity needed for high-speed Monster Truck driving. This design has become the industry standard for large-scale RC wheels because it dissipates heat effectively and allows for easier tyre mounting and removal.
- Precision Moulded Construction — Each wheel is produced using precision moulding from high-quality material, ensuring consistent dimensions and surface finish across every unit. This manufacturing precision is critical for maintaining balanced wheel sets and preventing vibration during high-speed runs, which directly improves handling characteristics and extends the lifespan of your drivetrain components.
- Reinforced 24mm Hub with Steel Insert — The wheel hub features a moulded-in steel insert that provides exceptional durability and prevents stripping of the hex fitting, even under the enormous torque and lateral forces generated by high-powered 8S brushless motors. This reinforcement is essential for large-scale RC vehicles where wheel retention and concentricity are absolutely critical to safe operation.
- 24mm Hex Fitment — The 24mm hex size is the standard specification for premium 1/5 scale ARRMA Monster Trucks, ensuring straightforward compatibility with models like the Kraton 8S and Outcast 8S without requiring any adapters or modifications. This fitment size provides excellent grip and engagement, minimising any play or movement that could compromise steering precision.
- Pair Supply Format — These wheels are supplied as a matched pair of two units, making them ideal for front and rear axle replacement or as a complete set for a fresh build. Having matched wheels ensures balanced performance across both axles and eliminates the common problem of mismatched wear characteristics.
- Front and Rear Compatibility — These wheels are suitable for both front and rear positions on compatible models, providing flexibility in your build configuration and allowing you to rotate wheels to even out wear patterns across your fleet of RC vehicles.
Technical Performance
The ARRMA MT Wheels deliver exceptional technical performance through their carefully engineered construction and material selection. With an overall wheel diameter of 4.9 inches (124mm), these wheels provide optimal ground clearance and approach angles for serious off-road exploration and high-speed running. The 3.54-inch (90mm) width ensures proper tyre mounting and support, whilst the 5.35-inch (136mm) overall width contributes to a stable, planted stance that enhances cornering performance and reduces rollover tendencies during aggressive driving manoeuvres. The 0.72-inch (18.2mm) wheel offset and 0.39-inch (10mm) axle hole diameter are precision specifications that integrate seamlessly with ARRMA's engineering tolerances. The reinforced 24mm hub with moulded-in steel insert represents the pinnacle of 1/5 scale wheel design, capable of withstanding the enormous loads and stresses generated by powerful 8S LiPo-powered brushless systems. The black colour finish provides a professional appearance and resists visible brake dust accumulation during extended running sessions. These specifications work together to create a wheel system that performs reliably under the demanding conditions of 1/5 scale Monster Truck operation, whether you are running on tarmac, gravel, sand, or mud surfaces.

Frequently Asked Questions
- What ARRMA Monster Trucks are these wheels compatible with? — These wheels are compatible with the ARRMA 1/5 Kraton 4X4 8S BLX EXB Brushless Monster Truck RTR and the ARRMA 1/5 Outcast 4X4 8S BLX EXB Brushless Stunt Truck RTR. The 24mm hex fitment and 4.9-inch diameter make them the correct specification for these premium large-scale models.
- Are these wheels suitable for beginners? — Yes, these wheels are suitable for anyone from beginners to experienced RC drivers. They are straightforward to fit to any compatible model with basic tools and provide immediately noticeable improvements to handling and appearance. If you are new to RC Monster Trucks and own a compatible ARRMA model, upgrading or replacing your wheels is one of the most accessible modifications you can make.
- Do I need to mount tyres onto these wheels myself? — The product specification indicates these are wheels only, not pre-mounted tyre and wheel packages. You will need to mount your own tyres onto these wheels using proper RC tyre mounting equipment or professional services available from most UK RC retailers. Many shops offer tyre gluing services if you do not have the equipment at home.
- What is the wheel offset and what does it mean? — The wheel offset of 0.72 inches (18.2mm) refers to the distance from the centreline of the wheel to the mounting face. This specification is critical for accurate chassis geometry and ensures that your suspension alignment remains correct and your steering response stays predictable. This offset is engineered to work with ARRMA's suspension geometry on compatible models.
- How do I know what tyres to buy for these wheels? — These wheels have a 4.9-inch (124mm) overall diameter and a 0.39-inch (10mm) axle hole diameter, meaning you need 4.9-inch Monster Truck tyres to mount on them. ARRMA manufactures several tyre options in the dBoots range specifically engineered for 4.9-inch wheels, and your local RC shop UK can advise on tyre selection based on your driving surface and style.
- Why do the wheels have a steel insert in the hex fitting? — The moulded-in steel insert reinforces the 24mm hex socket, preventing the plastic from deforming or stripping when you tighten your wheel nuts or when the wheels experience the enormous torque generated by 8S brushless motors. This is a premium feature that extends wheel lifespan and maintains a secure, precise fit to your axle shafts.
