Key Features

• Pre-assembled and factory-glued — These wheels and tyres arrive completely assembled and glued using Traxxas Ultra Premium Tire Glue, which means you can install them directly onto your vehicle without spending time on mounting, alignment, or gluing procedures, getting you on the track or field in minutes rather than hours.
• XRT Race black wheels with premium finish — The matte black XRT wheel design is not only visually striking but engineered to be strong and lightweight, providing an excellent foundation for aggressive driving whilst maintaining aesthetic appeal across a range of vehicle colours.
• Gravix race tyres with directional tread pattern — The low-profile 7.4 x 4.0 Gravix race tyres feature a specially engineered directional tread pattern that provides excellent traction on both track and wild terrain, running significantly quieter than traditional off-road tyres whilst delivering responsive handling characteristics.
• Dual profile design with foam inserts — The 4.3-inch outer and 5.7-inch inner dual profile construction, combined with integrated foam inserts, allows the tyres to maintain their shape during aggressive driving, preventing ballooning at high speed and delivering consistent contact patch pressure for superior grip and predictable steering response.
• Lightweight belting in the carcass — The Gravix tyres incorporate lightweight belting technology in the tyre carcass that maintains tyre shape for a larger contact patch, more grip, and responsive handling at any speed, whether you're sprinting on the track or navigating obstacles in the wild.
• 24mm splined hex fitting — The universal 24mm splined hexagonal hub connection ensures compatibility with multiple Traxxas platforms including XRT and X-Maxx vehicles, allowing these wheels to function as both replacement parts and performance upgrades.
• Left and right pair included — You receive a complete left and right wheel and tyre pair, so you can upgrade your vehicle's front and rear setup immediately, or swap out worn tyres without needing to source additional matched pairs.
• Ultra-tough 8S-rated glue bond — These wheels are assembled using professional-grade adhesive formulations rated for extreme 8S brushless power levels, ensuring the tyre-to-wheel bond remains secure even during maximum-throttle acceleration, high-speed cornering, and aggressive bashing.

Technical Performance

The Gravix race tyres represent a significant advancement in Traxxas tyre engineering, combining a thick centre carcass design with lightweight side wall construction to deliver performance across multiple driving styles and terrain types. The low-profile 7.4 x 4.0 dimensions place these tyres in the high-performance category, offering a balance between responsive steering feedback and aggressive traction characteristics. The directional tread pattern is specifically designed to reduce noise levels compared to traditional off-road tyre designs whilst maintaining excellent grip on both hard-packed surfaces and varied terrain. The dual profile construction (4.3-inch outer diameter, 5.7-inch inner diameter) maximises the contact patch during cornering whilst preventing ballooning during high-speed acceleration, a critical engineering consideration for 1/7 scale vehicles running at significant velocities. The foam inserts provide progressive support to the tyre sidewalls, allowing initial compliance for terrain absorption whilst preventing excessive deformation under load. The XRT Race black wheels themselves are engineered to be lightweight without compromising structural rigidity, reducing unsprung mass whilst maintaining the strength required for extreme driving conditions. The 24mm splined hex fitting is a proven Traxxas standard that provides secure, repeatable hub mounting with minimal runout. The factory glue bond utilises Traxxas Ultra Premium Tire Glue, a cyanoacrylate adhesive developed specifically for high-performance racing applications and tested to withstand centrifugal forces generated at over 100 mph, ensuring these wheels will remain secure during competitive events and enthusiast-level driving sessions.

Frequently Asked Questions

• Are these wheels and tyres ready to install straight from the box? — Yes, these wheels and tyres are completely pre-assembled and factory-glued using Traxxas Ultra Premium Tire Glue, so you can install them directly onto your Traxxas XRT or X-Maxx vehicle immediately without any additional setup, mounting procedures, or gluing processes required.
• What vehicles are these wheels and tyres compatible with? — These wheels and tyres are replacement parts specifically designed for the Traxxas XRT 1/7 scale truck platform, and they also function as optional accessories for the larger X-Maxx vehicle, providing upgrade options for both vehicle platforms with the 24mm splined hex fitting.
• How do the Gravix race tyres perform compared to other Traxxas tyre options? — The Gravix race tyres feature a directional tread pattern engineered to run quieter than traditional off-road designs whilst delivering excellent traction on both track and varied terrain, with a thick centre carcass that prevents ballooning at high speed and lightweight belting that maintains tyre shape for a larger contact patch and superior grip.
• Can I use these wheels with my existing Traxxas RC car? — These wheels feature a 24mm splined hex fitting that is compatible with Traxxas XRT vehicles (the specified replacement part) and X-Maxx vehicles (as optional accessories), so compatibility depends on your specific model platform; check your vehicle's hex fitting size to confirm compatibility.
• What is the difference between pre-glued wheels and manually glued wheels? — Pre-glued wheels like the TRX7872 save significant preparation time and ensure professional-quality glue application using Traxxas Ultra Premium Tire Glue, whereas manually glued wheels require cleaning the mounting surfaces with isopropyl alcohol, applying glue in sections, and waiting for proper curing, which typically takes considerably longer.
• How do the foam inserts improve tyre performance? — The foam inserts provide progressive support to the tyre sidewalls, allowing the tyres to absorb terrain impacts whilst preventing excessive deformation during high-speed cornering and aggressive acceleration, resulting in more consistent contact patch pressure, improved grip, and more predictable handling characteristics.
• Are these wheels suitable for wet or muddy conditions? — The Gravix tyre design with its directional tread pattern performs well in varied conditions including wet terrain, and the foam inserts help maintain tyre shape even when operating in challenging environments, though for extreme water conditions some drivers prefer to add tyre vents using a leather punch to allow water to escape through centrifugal force.
• What glue was used to assemble these wheels? — These wheels are assembled using Traxxas Ultra Premium Tire Glue, a professional-grade cyanoacrylate adhesive specifically developed for high-performance racing applications and rated for extreme 8S brushless power levels, providing a secure bond that withstands centrifugal forces at over 100 mph.
