Overview

The Traxxas Wheels & Tyres, Assembled, Glued (X-Maxx Black Chrome wheels, Sledgehammer belted tyres, dual profile (4.3in outer, 5.7in inner), foam inserts) (left & right) TRX7871X represents a premium accessory upgrade for your 1/7 scale Traxxas X-Truck. Whether you're a dedicated RC enthusiast searching for the best ready-to-run RC truck upgrade in the UK or a competitive racer looking to maximise performance, these assembled and pre-glued wheels and tyres offer game-changing stability and control that will transform your high-speed off-road experience. This is not just a tyre and wheel set—it's an engineered system designed to deliver superior grip, responsive handling, and a commanding stance that turns heads at the track or on the trail.

Sledgehammer belted tyres have become the benchmark for serious RC enthusiasts who demand the best from their vehicles. Whether you're slinging mud through wet conditions or setting speed records on hard-packed terrain, these tyres deliver consistent performance across a wide variety of surfaces. The Sledgehammer's distinctive wide, open-block tread design is engineered to resist clogging with dirt and debris—a critical advantage when you're pushing your X-Truck to its limits in challenging environments. At 8.4 inches tall, these tyres give your X-Maxx or XRT an impressively powerful stance with visibly increased ground clearance, enhancing both the aesthetic appeal and the practical off-road capability of your machine.

What sets the TRX7871X apart in the competitive world of RC car upgrades is the complete assembly and gluing—everything arrives ready to bolt onto your vehicle. You receive a pair of massive 6-spoke black chrome X-Maxx wheels pre-mounted with Sledgehammer belted tyres, foam inserts already installed, and secured with an ultra-tough 8S-rated glue bead. This level of preparation means you can spend more time driving and less time in the workshop. The black chrome finish on the wheels complements the aggressive styling of modern Traxxas X-Trucks whilst maintaining durability and aesthetic appeal through countless bashful sessions.

Key Features

• Belted Sledgehammer Tyres — The lightweight belting construction maintains the tyre's shape precisely, creating a larger contact patch that translates directly into more grip and substantially improved responsive handling at any speed, from low-speed technical driving to high-speed blasts across open terrain.
• Wide Open-Block Tread Design — The carefully engineered tread pattern resists clogging with dirt, mud, and debris, meaning your tyres maintain consistent performance throughout extended driving sessions without degradation from packed-in material that would otherwise reduce grip.
• Increased Diameter and Ground Clearance — At 8.4 inches in height, these tyres provide your X-Truck with a more powerful, aggressive stance whilst delivering even higher ground clearance for traversing obstacles and challenging terrain that would ground out shorter tyres.
• Pre-Mounted and Pre-Glued Assembly — Both wheels arrive completely assembled with tyres glued, foam inserts installed, and ready for immediate installation onto your vehicle, eliminating the time-consuming process of mounting, gluing, and balancing tyres yourself.
• Massive 6-Spoke Black Chrome Wheels — These large-scale wheels feature a striking black chrome finish that enhances the visual impact of your truck whilst providing genuine strength and durability for sustained high-performance driving and extreme bashing.
• Ultra-Tough 8S-Rated Glue Bead — The glue bond is specifically formulated and rated to handle 8S LiPo power systems, ensuring the tyres remain permanently secured even under the extreme forces generated by high-speed runs and aggressive acceleration, cornering, and braking.
• Dual Profile Construction — The dual profile design (4.3 inch outer, 5.7 inch inner) provides optimised weight distribution and handling characteristics across different driving conditions, delivering performance advantages across both on-road passes and off-road exploration.
• 24mm Splined Hex Compatibility — The wheels fit standard 24mm splined hex hubs, allowing installation on the front or rear of compatible Traxxas models, providing flexibility in how you configure your vehicle's footprint and suspension geometry.
• Pair Included — You receive two complete wheel and tyre assemblies (left and right), sufficient for a complete upgrade of either the front and rear axles or to replace a damaged set and keep a spare ready for immediate deployment at the track.

Technical Performance

The Traxxas Sledgehammer belted tyres represent a significant advancement in tyre technology specifically engineered for the extreme demands of 1/7 scale RC truck driving. The lightweight belting system is the key engineering innovation—rather than adding weight and complexity, the belts maintain tyre shape under the tremendous lateral and longitudinal forces experienced during high-speed cornering and acceleration. This shape retention creates a larger, more consistent contact patch between the tyre and the ground, which directly improves grip levels and enables more predictable, responsive handling characteristics. The wide, open-block tread pattern has been specifically designed to shed dirt and debris rather than accumulating material in the tread voids—a common problem with traditional closed-tread designs that progressively lose grip as packed mud and soil reduces the effective tread depth. The 8.4-inch overall diameter provides a substantial increase in wheel size compared to standard fitment, translating to improved ground clearance for obstacle traversal and a more commanding visual presence. The pre-assembly and pre-gluing process uses an ultra-tough, 8S-rated glue formulation that bonds the tyre bead to the wheel rim with sufficient strength to withstand repeated impacts, high-speed runs, and the extreme forces generated by brushless motor systems running at full throttle. The black chrome wheel finish combines aesthetic appeal with practical durability, resisting corrosion and maintaining appearance through wet, muddy conditions. The dual profile construction optimises performance across varied terrain by balancing sidewall compliance and structural rigidity. These wheels and tyres are fully compatible with Traxxas X-Maxx, X-Maxx Ultimate, XRT, and XRT Ultimate models, making them an ideal upgrade for anyone running a late-model Traxxas X-Truck platform.

Frequently Asked Questions

• Which Traxxas models are these wheels and tyres compatible with? — The TRX7871X wheels and tyres fit 24mm splined hex hubs and are designed as accessory parts for the X-Maxx Belted 4WD Brushless RTR 8S Monster Truck (available in orange, blue, red, and green), the X-Maxx Ultimate (available in blue and green variants), the XRT VXL-8S (available in green, black, blue, and orange), and the XRT Ultimate (available in blue and green variants). If you own any of these models, these tyres are a direct fit for your vehicle.
• Are these wheels and tyres delivered assembled and ready to fit? — Yes, the TRX7871X arrives completely assembled with the tyres pre-mounted to the wheels, glued with an 8S-rated adhesive, and with foam inserts already installed. You simply unbag them and bolt them onto your vehicle's 24mm hex hubs—no additional assembly, gluing, or preparation is required.
• What is the advantage of belted tyres over standard tyre designs? — Belted tyres use a lightweight internal structure that maintains the tyre's shape under cornering and acceleration forces, creating a larger contact patch with the ground. This translates to improved grip, more responsive handling, and better performance at any speed. The belting also allows the tyre to maintain its profile even during extreme driving conditions, providing consistency that non-belted alternatives cannot match.
• Will these tyres work with non-Traxxas vehicles? — These wheels feature a 24mm splined hex mounting system, so they will fit any RC truck or monster truck equipped with 24mm splined hubs. Whilst designed for Traxxas X-Maxx and XRT models, you may find them compatible with other compatible platforms from ARRMA, Losi, or other manufacturers using the same hex standard, though Traxxas specifically recommends them for X-Truck applications.
• How long do the tyres last before needing replacement? — Tyre lifespan depends entirely on driving conditions and intensity. Sledgehammer tyres are extremely durable and designed for sustained high-speed running, but continuous high-speed bashing on abrasive surfaces will eventually wear the tread. Most users report significantly extended lifespan compared to standard non-belted alternatives, but eventual replacement is inevitable with heavy use.
• Can I use these on both the front and rear of my X-Maxx? — Yes, the wheels fit 24mm splined hubs on both the front and rear axles, and Traxxas specifies them as suitable for either position. You may choose to run them on just one axle or both, depending on your driving style and preferences.
• What is the advantage of the 8.4-inch tyre diameter? — The increased diameter provides multiple benefits: visibly higher ground clearance for obstacle traversal, a more aggressive and powerful stance that enhances the visual appeal of your truck, and improved ability to roll over terrain features that would challenge smaller-diameter tyres. The larger diameter also affects the overall gearing and top speed characteristics of your vehicle.
• Are the foam inserts necessary? — The foam inserts are included and serve to support the tyre bead, maintain tyre shape at low pressures, and prevent tyre rollover during high-speed cornering. They are an essential component of the assembly and contribute significantly to handling characteristics.
