Traxxas XRT Race Wheels 1/7 Scale Black 24mm Hex Pair TRX7874

Overview

The Traxxas Wheels, XRT Race, Black (left and right) TRX7874 are purpose-built racing wheels designed for high-performance RC truck enthusiasts across the UK. Whether you're running your XRT at the track or bashing in the wild, these black wheels deliver the perfect blend of style and functionality. The matte black finish gives your RC truck a high-tech, professional appearance that stands out on any terrain. These are genuine Traxxas replacement parts engineered to the same exacting standards as the vehicles they're designed for.

If you own a Traxxas XRT or are looking to upgrade your X-Maxx with genuine OEM wheels, this pair represents the ideal solution for serious RC enthusiasts in the UK who demand quality and reliability. The wheels come pre-assembled with Gravix race tyres, meaning they're ready to bolt on and go — no additional setup or gluing required. This is a replacement part for the XRT model range and works as an accessory upgrade for X-Maxx vehicles, making them versatile across Traxxas's large-scale truck lineup.

Built with performance in mind, these wheels feature a massive 24mm splined hub that maximises surface contact and ensures maximum durability during high-speed runs. Whether you're competing in time trials, enjoying casual weekend bashing, or testing your RC truck's limits on the track, the XRT Race Wheels provide the foundation your vehicle needs for optimal handling and control.

Key Features

• Low-profile Gravix Race Tyres — The 7.4-inch by 4.0-inch Gravix race tyres are engineered specifically for hard track running and wild outdoor bashing, featuring a directional tread pattern that runs significantly quieter than traditional off-road RC tyres whilst maintaining excellent traction across varied surfaces.
• Thick Centre Carcass Construction — The tyres feature a reinforced thick centre carcass that actively prevents ballooning at high speeds, meaning you can push your RC truck to its limits without worrying about tyre deformation or loss of grip under extreme cornering forces.
• Pre-assembled and Pre-glued — These wheels come to you completely ready to use — the Gravix race tyres are already mounted and glued to the matte black wheels with foam inserts fitted, saving you hours of preparation time and the guesswork of getting glue and bead seat angles exactly right.
• Matte Black Finish — The distinctive matte black XRT wheels deliver a modern, professional aesthetic that complements any RC truck build and resists showing dust and dirt more effectively than glossy finishes.
• 24mm Splined Hub Design — The huge 24mm splined hub maximises surface contact between the wheel and axle, providing superior durability and reliability during intense driving sessions, whether you're on track or thrashing through rough terrain.
• Universal Fitment — These wheels fit any RC vehicle with a 24mm splined hex fitting, making them suitable for both front and rear positions and opening compatibility with multiple vehicles in the Traxxas range and beyond.
• Left and Right Pairing — You receive one left and one right wheel, providing everything needed to replace a complete axle set or to upgrade both front and rear positions on compatible vehicles.

Technical Performance

The Traxxas XRT Race Wheels represent the pinnacle of engineering for large-scale RC truck applications. At 7.4 inches in diameter with a 4.0-inch width, these low-profile racing tyres strike the perfect balance between ground clearance, cornering stability, and acceleration response. The directional tread pattern isn't merely aesthetic — it's acoustically optimised to run noticeably quieter than traditional off-road RC tyres, a significant advantage whether you're racing at indoor or outdoor facilities where noise restrictions apply. The thick centre carcass is constructed to withstand the tremendous forces generated during high-speed runs; this prevents the ballooning effect that plagues lesser-quality RC tyres, where the sidewalls expand under cornering load and robbing you of precise handling feedback. The pre-glued foam inserts are critical for maintaining tyre integrity and preventing internal movement that could lead to tyre loss or performance degradation. Built in genuine Traxxas quality using proven materials and manufacturing techniques, these wheels deliver the performance consistency that competitive RC drivers and serious hobbyists demand. The 24mm splined hub is engineered to the same tolerances as Traxxas's complete vehicle platforms, ensuring perfect fitment and eliminating slop or movement that could compromise handling. Whether you're investing in these as a replacement set or as an upgrade for your existing XRT or X-Maxx, you're choosing a component that has been field-tested by professional RC drivers and proven in competition environments across the UK and worldwide.

Frequently Asked Questions

• Are these wheels suitable for both track racing and off-road bashing with my Traxxas XRT? — Yes, absolutely. The Gravix race tyres are specifically designed to perform excellently in both environments. The directional tread pattern and thick centre carcass make these tyres versatile enough for competitive track time whilst remaining capable on rough outdoor terrain, making them an ideal all-purpose choice for serious RC enthusiasts who don't want to maintain multiple tyre sets.
• Do these wheels come ready to use straight from the box? — Yes, these are completely pre-assembled and pre-glued. The Gravix race tyres are already mounted to the matte black wheels with foam inserts installed. You simply fit them to your vehicle using the 24mm splined hex fitting — no additional gluing, mounting, or setup is required, saving you valuable preparation time.
• What does the thick centre carcass in these Gravix tyres actually do? — The thick centre carcass actively prevents ballooning, which is the unwanted expansion of the tyre sidewalls under high-speed cornering loads. By preventing this deformation, the tyres maintain consistent grip, predictable handling characteristics, and their intended shape, allowing you to push your RC truck harder with greater confidence.
• Why are these tyres quieter than traditional off-road RC tyres? — The directional tread pattern on these Gravix race tyres is engineered to minimise noise generation as the tyre rolls and makes contact with the surface. This is achieved through precise pitch variations in the tread blocks and tread depth optimisation, making these tyres excellent for facilities or times when noise restrictions are in place, whilst still delivering exceptional performance.
• Can I use these wheels on my X-Maxx as well as my XRT? — Yes, these wheels are listed as compatible accessory upgrades for the entire X-Maxx Belted 4WD Brushless RTR 8S Monster Truck range (all colours) and the X-Maxx Ultimate variants. As long as your vehicle uses the 24mm splined hex fitting, these wheels will fit both front and rear positions.
• What is the scale of these wheels? — These are 1/7 scale wheels designed for large-scale Traxxas trucks. The 7.4-inch diameter and 4.0-inch width make them proportionally accurate for this scale class.
• Are these genuine Traxxas parts? — Yes, these are genuine OEM Traxxas components manufactured to the same exacting specifications as the vehicles they're designed for. The model number TRX7874 identifies them as authentic Traxxas products.
