What sets this product apart in the RC car UK market is the combination of premium Sledgehammer tyres with Traxxas's ultra-tough XRT race wheels, all assembled with Traxxas Ultra Premium Tire Glue and rated for extreme 8S brushless power. The factory assembly means you're receiving the exact same quality and precision that Traxxas applies to their complete ready-to-run RC trucks. These aren't generic wheels and tyres—they're purpose-built for maximum performance on loose surfaces and technical terrain, with engineering that traces back to the development of Traxxas's legendary high-speed models.

Sold as a left and right pair and fitting the standard 24mm splined hex mounting system, these wheels are compatible with multiple X-Maxx and XRT models, making them an ideal upgrade for drivers ready to tackle more aggressive terrain or enhance their vehicle's capabilities.

Key Features

• Ultra-Rugged Sledgehammer Tyres — The Sledgehammer tyre design delivers extreme traction and control across a diverse range of off-road terrain, from rocky trails to loose dirt and sand. The open block tread pattern is specifically engineered to clear mud and debris efficiently, preventing tread clogging and maintaining consistent grip even in the messiest conditions.
• 8.4-Inch Tyre Diameter — At 8.4 inches tall, these Sledgehammer tyres provide a significant increase in diameter compared to standard options, giving your X-Truck a more powerful, aggressive stance while simultaneously increasing ground clearance. This larger footprint translates to better obstacle negotiation and improved weight distribution across variable terrain.
• Matte Black XRT Wheels — The massive matte black XRT wheels feature a rugged, competition-grade aesthetic that complements high-performance RC trucks. The matte finish provides a professional appearance whilst the wheel design is optimised for strength and lightweight performance, crucial for maintaining stability at extreme speeds.
• Factory-Assembled and Pre-Glued — These wheel and tyre assemblies arrive pre-mounted and pre-glued with Traxxas Ultra Premium Tire Glue, eliminating hours of assembly work. The glue used is the same ultra-strong cyanoacrylate adhesive that Traxxas developed for their record-breaking 100+mph models—it's engineered to hold tight at extreme RPM and withstand the forces generated by brushless 8S power systems.
• 8S-Rated Glue Bead — The ultra-tough glue bead is specifically rated for 8S brushless systems, meaning these wheels can handle the extreme torque and centrifugal forces generated by high-powered electric RC trucks without tyre separation or drift.
• Foam Inserts Included — Each tyre comes with integrated foam inserts that provide structural support and consistent sidewall flex characteristics. These inserts are critical for maintaining tyre shape during high-speed cornering and off-road impacts, preventing tyre rollover and ensuring predictable handling.
• 24mm Splined Hex Fitting — The standard 24mm splined hex connection fits multiple Traxxas models including the X-Maxx and XRT ranges, making these wheels a flexible upgrade option for drivers with multiple vehicles or those planning future model expansion.
• Left and Right Configuration — Sold as a matched pair (one left, one right), these wheels are ready to install on the front or rear of your RC truck without additional configuration or modification.

Technical Performance

These pre-assembled wheel and tyre units represent Traxxas's commitment to factory-grade precision and extreme performance engineering. The combination of 8.4-inch Sledgehammer tyres with matte black XRT wheels is specifically optimised for brushless 8S systems, delivering predictable handling characteristics and exceptional traction across loose surfaces. The tyres feature an open block tread design that has been rigorously tested to clear mud and debris whilst maintaining mechanical grip on rocks, dirt, and sand. The foam inserts provide consistent sidewall support and prevent tyre flex from becoming excessive during aggressive cornering or high-speed landings. Traxxas Ultra Premium Tire Glue creates an unbreakable bond between the tyre bead and wheel channel, tested and proven to maintain integrity at speeds exceeding 100mph and the extreme RPM figures generated by brushless motors. The glue develops exceptional strength through a cyanoacrylate chemistry that was specifically formulated to exceed the bonding requirements of high-performance RC applications. The matte black XRT wheels are engineered from high-strength materials capable of handling the impact forces inherent in large-scale RC driving, with a design that balances weight and structural rigidity for optimal performance.

Frequently Asked Questions

• Are these wheel and tyre assemblies ready to install on my Traxxas RC truck? — Yes, these pre-assembled and pre-glued wheels are ready to install immediately. Simply mount them onto your vehicle's 24mm splined hex hubs—no additional assembly, cleaning, or gluing is required. This is perfect for drivers who want immediate performance upgrades without the time investment of manual tyre mounting.
• What RC models are these wheels compatible with? — These TRX7876 wheel and tyre assemblies fit multiple Traxxas models including the X-Maxx Belted 4WD brushless models, X-Maxx Ultimate models, and XRT VXL-8S and XRT Ultimate models. The 24mm splined hex fitting is standard across these lines, and the 8S-rated glue bond makes them ideal for high-powered brushless variants of these trucks.
• Why does the Sledgehammer tyre size matter, and what advantages does the 8.4-inch diameter provide? — The 8.4-inch diameter is significantly larger than standard options, providing multiple performance benefits. The increased tyre size raises your vehicle's centre of gravity only slightly whilst dramatically improving ground clearance for obstacle navigation. The larger contact patch improves traction on loose surfaces, and the increased rotational mass helps maintain momentum through varied terrain. For serious off-road driving and technical trail courses, this larger diameter is essential for competitive performance.
• What is the difference between factory-glued wheels and assembling tyres myself? — Factory-glued assemblies eliminate the need for Traxxas Ultra Premium Tire Glue, cable wraps, alcohol cleaning, and hours of careful assembly work. Traxxas's factory technicians use the same techniques and materials described in their official assembly guides, ensuring optimal glue distribution and curing. For drivers who want maximum performance without the assembly complexity, pre-glued wheels offer professional-grade results with zero guesswork. However, if you prefer to rebuild your own tyres or experiment with different tyre brands on these wheels, beadlock alternatives are available.
• Will these wheels work with my brushless 8S RC monster truck? — Absolutely. The 8S-rated glue bond is specifically engineered for brushless systems operating at 8S power levels. These wheels have been tested to maintain structural integrity during the extreme RPM and centrifugal forces generated by brushless motors, which operate at much higher speeds than brushed alternatives. The open block tread of the Sledgehammer tyre is also optimised for the speed and power delivery characteristics of brushless systems.
• Do these tyres come with foam inserts? — Yes, foam inserts are included with each tyre. These provide essential sidewall support and flex characteristics, maintaining consistent handling during high-speed cornering and impact absorption on rough terrain. The foam inserts are factory-installed and integrated into the tyre assembly.
• Can I use these wheels on other Traxxas models or RC trucks from other manufacturers? — The 24mm splined hex fitting is standard across multiple Traxxas large-scale models, but compatibility beyond the listed X-Maxx and XRT models should be verified before purchase. These wheels are specifically engineered for Traxxas platforms and are not designed for use with other manufacturer's RC vehicles.
• What terrain are Sledgehammer tyres best suited for? — Sledgehammer tyres excel on loose surfaces including dirt, sand, gravel, and rocky terrain. The open block tread design clears mud and debris effectively, making them ideal for unprepared trails and natural landscapes rather than smooth, paved surfaces. They're equally at home in muddy conditions thanks to their self-cleaning tread pattern that flings debris outward under centrifugal force.
