Key Features

• Belted Sledgehammer All-Terrain Tyres — The belted construction maintains the tyre's shape even under extreme loads and high speeds, creating a larger contact patch that translates directly into more grip and responsive handling whether you're slinging mud, tearing through sand, or setting speed records on hard-packed terrain.
• Wide, Open-Block Tread Design — Unlike solid or closely-spaced tread patterns that clog with dirt and debris, the open-block design of the Sledgehammer tyres self-cleans as you drive, ensuring consistent traction throughout your session without the performance degradation that comes with packed mud or grass.
• Dual Profile Construction (2.9in outer, 3.8in inner) — This innovative dual profile geometry provides the best of both worlds: the outer diameter optimises visual proportions and stance, whilst the inner diameter ensures proper fit and engagement with your truck's wheel hexes and suspension geometry for reliable, consistent performance.
• Large Diameter for Powerful Stance and Ground Clearance — The Sledgehammer's impressive diameter doesn't just make your Traxxas WideMaxx or compatible monster truck look more aggressive—it provides genuine functional benefits including increased ground clearance for obstacle clearance, improved suspension travel utilisation, and a lower rolling resistance ratio that enhances speed potential.
• Gloss Black Wheels with Professional Finish — The precision-manufactured gloss black wheels complement the aggressive styling of the Sledgehammer tyres, creating a finished appearance that looks race-ready straight out of the box and matches the aesthetic of modern high-performance RC monster trucks.
• Pre-Mounted and Pre-Glued Assembly — Traxxas has done all the hard work for you—these tyres arrive mounted on the wheels and glued with an ultra-tough glue bead that's formulated to withstand the extreme forces of high-speed off-road driving without separation or failure.
• Ultra-Tough Glue Bead Technology — The specialised adhesive formula bonds the tyre to the wheel with exceptional strength, engineered specifically for the violent impacts, rapid deceleration, and extreme cornering forces experienced during serious high-speed bashing and racing.
• 17mm Splined Hex Fitting — The universal 17mm splined hex connection ensures compatibility with a wide range of Traxxas and other 1/8 scale RC trucks, including the popular Traxxas WideMaxx Monster Truck in all colour variants (Red, Rock N Roll, Green and others).
• Front or Rear Installation Capability — The balanced design of these assemblies makes them suitable for use on either the front or rear axles of your RC truck, offering flexibility in your setup and allowing you to upgrade your vehicle incrementally or completely.
• TSM Compatibility Rating — These tyres are tested and certified compatible with Traxxas Stability Management systems, meaning you can run them with complete confidence knowing they've been validated to work seamlessly with your truck's advanced traction control features.
• Foam Inserts for Realistic Ride Height — The included foam inserts provide the correct ride height and suspension geometry, ensuring your truck maintains proper articulation, ground clearance, and handling characteristics precisely as Traxxas engineers intended.
• Pair Quantity for Complete Coverage Options — You receive two complete assemblies per pack, giving you enough to outfit both front wheels, both rear wheels, or to have a complete spare set for track day competitions or extensive bashing sessions.

Technical Performance

The Sledgehammer All-Terrain tyre represents the pinnacle of Traxxas's tyre engineering expertise, combining precision manufacturing with real-world performance validation. The belted construction is critical to understanding why these tyres perform so differently from standard all-terrain rubber. The lightweight belting layer runs through the tyre's sidewall structure, maintaining the tyre's profile under load and during rapid acceleration or cornering, preventing the deformation that would otherwise reduce the contact patch and compromise traction. This engineering directly translates to larger contact area against the ground, more grip during acceleration and cornering, and responsive handling at all speeds from low-speed technical driving through high-speed racing runs. The tyre's outer diameter of 2.9 inches and inner diameter profile of 3.8 inches have been precisely calculated to deliver optimal rolling characteristics whilst maintaining proper engagement with the wheel hex and suspension geometry of 1/8 scale monster trucks. The foam inserts provide consistent sidewall support and suspension characteristics essential for maintaining handling predictability across varying terrain and driving styles. These assemblies mount directly to your truck's 17mm splined hex axle and wheel hubs—no additional modification or fitment work is required. The ultra-tough glue bead has been specifically formulated and stress-tested to withstand the extreme forces of high-speed off-road driving, including rapid cornering loads, landing impacts from jumps, and the rotational forces generated by powerful brushless motors. Traxxas's TSM (Traxxas Stability Management) rating confirms that these tyres have been tested and validated to work correctly with electronic stability control systems, ensuring predictable traction delivery and control behaviour. Whether you're using these on a bone-stock truck or pushing the performance envelope with upgraded motors and ESCs, the Sledgehammer tyres maintain their excellent grip characteristics and reliable performance.

Frequently Asked Questions

• What is the difference between belted and non-belted all-terrain tyres for RC trucks? — The belted construction in the Sledgehammer tyres provides a reinforcement layer that maintains the tyre's shape under extreme loads and high-speed driving. Non-belted tyres tend to deform during cornering and acceleration, reducing the contact patch and compromising grip. The belting in Sledgehammer tyres keeps the sidewalls firm, delivering a consistently larger contact patch and more responsive handling throughout your driving session, even as the tyres heat up during extended bashing or racing.
• Will these tyres fit my Traxxas truck? — These assemblies are designed for trucks with 17mm splined hex wheel mounts and are specifically compatible with the Traxxas WideMaxx Monster Truck in all colour variants (Red, Rock N Roll, and Green). They also fit many other 1/8 scale RC trucks with 17mm splined hex axles. However, we recommend checking your truck's specifications or contacting our team to confirm compatibility before ordering if you're uncertain about your specific model.
• Are the tyres pre-glued and ready to install immediately? — Yes, these arrive completely pre-mounted and pre-glued with an ultra-tough adhesive bead. You simply remove them from the packaging and fit them directly to your truck's wheel hexes. No additional gluing, tyre mounting, or preparation is required—they're truly ready to use immediately.
• What does TSM rated mean and why is it important? — TSM (Traxxas Stability Management) is an electronic stability control system that helps manage traction and prevent loss of control. TSM-rated tyres have been tested and certified by Traxxas to work correctly with vehicles equipped with this system, ensuring predictable traction delivery and control behaviour. If your truck has TSM, using TSM-rated tyres ensures optimal performance of that system.
• Can I use these tyres on the front and rear of my truck? — Yes, the balanced design of these assemblies makes them suitable for use on either front or rear axles. This gives you flexibility in your setup—you can upgrade just one axle or outfit your entire truck with fresh rubber.
• What terrain are Sledgehammer tyres best suited for? — The open-block tread design and all-terrain classification make Sledgehammer tyres versatile across multiple surfaces including mud, grass, dirt, sand, and hard-packed terrain. The wide tread blocks won't clog with mud or debris, maintaining consistent traction throughout your session. Whether you're a weekend basher exploring varied terrain or a racer looking for reliable performance across different track conditions, these tyres deliver.
• How many tyres do I get in this pack? — This pack contains two complete wheel and tyre assemblies, which is enough to outfit either your front or rear axles completely, or to have complete spares for competition or extended bashing sessions.
• What is the wheel size and what does the dual profile (2.9in outer, 3.8in inner) mean? — The outer diameter of 2.9 inches is the tyre's overall diameter for rolling and speed calculations. The 3.8-inch inner diameter measurement refers to the overall wheel assembly dimension. This dual profile design has been precisely engineered to deliver optimal visual proportions, proper fit on your truck's hex mounts, and ideal suspension geometry and handling characteristics.
