Key Features

• Belted Sledgehammer Tyres — The Sledgehammer belted tyres deliver game-changing stability and control whether you are slinging mud or setting speed records. Unlike conventional unbelted tyres, the belted construction provides reinforcement that maintains the tyre's shape under extreme driving conditions, resulting in a larger contact patch with the ground and significantly improved grip at any speed.
• Open-Block Tread Design — The wide, open-block tread pattern is specifically engineered to prevent dirt and debris from clogging up the tyre surface. This design means your tyres maintain consistent grip even when driving through muddy, dusty or sandy terrain, and you spend less time cleaning your RC vehicle after a session.
• Lightweight Belting Technology — The belts are engineered to be lightweight, meaning they enhance tyre performance without adding excessive unsprung weight to your vehicle. This maintains responsive handling and keeps your suspension working efficiently, whether you are driving on road-like surfaces or aggressive off-road terrain.
• 8.4 Inch Tall Diameter — At 8.4 inches tall, these Sledgehammer tyres are significantly larger than stock rubber. This increased diameter gives your X-Maxx a more powerful, aggressive stance whilst simultaneously providing even higher ground clearance. Greater ground clearance means you can tackle more challenging terrain without the chassis or underbody hitting obstacles.
• Dual Profile Design (4.3in Outer, 5.7in Inner) — The dual profile construction features a 4.3 inch outer diameter and 5.7 inch inner diameter, creating a specific tyre profile optimised for both stability and cornering. This geometry has been engineered by Traxxas to work in harmony with the X-Maxx suspension for predictable, responsive handling.
• Massive 6-Spoke Black X-Maxx Wheels — The wheels are large-scale components featuring a distinctive 6-spoke design finished in black. These are not lightweight plastic wheels — they are engineered to be ultra-tough and capable of handling the extreme forces generated by high-speed off-road driving.
• Ultra-Tough 8S-Rated Glue Bead — The tyres come pre-glued to the wheels using an 8S-rated adhesive bead. The 8S rating means this glue is engineered for the extreme vibrations and forces generated by vehicles running on 8S LiPo battery packs. This ultra-tough glue means your tyres will remain securely mounted even during the most aggressive driving sessions.
• Pre-Mounted and Pre-Glued Assembly — Unlike buying tyres and wheels separately, the TRX7871 comes completely assembled and glued, ready to install on your vehicle. Simply swap them onto your 24mm splined hex hubs and you are ready to drive, eliminating the time-consuming process of mounting and gluing tyres yourself.
• 24mm Splined Hex Fitting — These wheels fit all 24mm splined hex hubs found on X-Maxx and XRT vehicles. The splined connection ensures a secure, positive fit that will not slip or come loose during aggressive driving.
• Front or Rear Compatibility — The TRX7871 wheel and tyre assembly can be fitted to either the front or rear axles of your vehicle, providing complete flexibility in your configuration. Customers can purchase multiple sets to upgrade all four wheels, or mix and match with other wheel options.
• Foam Inserts Included — The assembly includes foam inserts that work in conjunction with the tyres and wheels to provide shock absorption and improve handling characteristics. These inserts are engineered to work with the dual profile tyre design.

Technical Performance

The Traxxas TRX7871 represents significant engineering advancement in large-scale RC tyres. The belted tyre construction is fundamentally different from traditional unbelted rubber — the reinforcement belts run circumferentially around the tyre, providing structural support that prevents the tyre from bulging and deforming under the extreme forces experienced during high-speed driving. This maintains a consistent, optimal contact patch with the ground, which directly translates to improved grip, more predictable handling, and better traction in mud, dirt, sand and other off-road surfaces. The lightweight nature of the belting means this performance improvement comes without compromising the vehicle's acceleration or overall handling dynamics.

Built for 1/6 scale vehicles like the X-Maxx and XRT, these are truly large-scale components. The 8.4-inch tall tyre combined with the massive 6-spoke wheels creates an imposing, purposeful appearance that matches the aggressive engineering of these premium monster trucks. The 8S-rated glue bead is specifically engineered for vehicles running 8S LiPo battery systems, which deliver the enormous power and torque that define modern monster truck racing in the UK and internationally. The glue has been tested and proven to withstand the extreme vibrations and forces generated at high speeds, ensuring your tyres will not slip or dislodge mid-session.

The wheel and tyre combination is engineered to maintain structural integrity even under the most extreme driving conditions. Whether you are performing high-speed jumps on custom tracks, blasting through muddy fields, or pushing your X-Maxx to its absolute limit on tarmac, this assembly has been designed to handle the punishment. The open-block tread pattern continues to provide traction even as it wears, meaning performance remains consistent throughout the tyre's lifespan. Installation is straightforward — these fit any vehicle using 24mm splined hex hubs, making them a direct upgrade option for X-Maxx and XRT owners.

Frequently Asked Questions

• What vehicles are these Sledgehammer belted tyres compatible with? — The TRX7871 wheel and tyre assembly is designed as an accessory part for the Traxxas X-Maxx and Traxxas XRT platforms. These are 1/6 scale vehicles, making them amongst the largest and most powerful brushless RC trucks available. The 24mm splined hex fitting ensures compatibility with both models. The 8S-rated glue bead means these tyres are optimised for the extreme performance these vehicles deliver.
• How do belted tyres improve performance compared to standard RC tyres? — Belted tyres use reinforcement belts running around the tyre circumference, which maintains the tyre's shape under extreme driving forces. This keeps the contact patch consistent and maximises grip, resulting in more predictable handling, better traction in mud and dirt, and improved overall stability. The lightweight belting adds this performance without significantly increasing unsprung weight, so your suspension and handling dynamics remain responsive.
• Are these tyres suitable for all types of terrain? — Yes. The open-block tread design and belted construction make these Sledgehammer tyres highly versatile. The wide, open-block pattern prevents dirt and debris from clogging, making them ideal for muddy and sandy conditions.
