Traxxas X-Maxx Wheels and Tyres 1/7 Gravix Black Assembled Glued TRX7877

Overview

The Traxxas Wheels & Tyres, Assembled, Glued (X-Maxx Black wheels, Gravix Tyres, foam inserts) (left & right) TRX7877 are premium replacement wheel and tyre sets designed for serious RC enthusiasts who demand professional-grade performance. These pre-assembled and glued wheel packages come ready to bolt straight onto your Traxxas X-Maxx or XRT monster truck without any faffing about with assembly or gluing. Whether you are running a brushless RC 4WD monster truck for weekend bashing, competitive track racing, or extreme off-road adventures, these wheel and tyre combinations deliver the kind of reliability and performance that Traxxas is renowned for across the RC car UK market.

As an 1/7 scale setup, the TRX7877 represents the perfect upgrade or replacement option for drivers who want to maximise their truck's potential on any terrain. The low-profile design and premium Gravix race tyres provide the kind of grip, stability and handling characteristics that separate casual RC drivers from serious competitors.

These wheels are sold as a matched pair (left and right), meaning you get everything needed to upgrade either the front and rear, or to refresh your entire setup with fresh rubber. The matte black X-Maxx wheels complement any colour chassis and provide a professional appearance that matches the performance underneath.

Key Features

• Low-profile 7.4" x 4.0" Gravix race tyres — These are purpose-built racing tyres engineered to perform hard at the track or in wild terrain, delivering consistent grip and predictable handling across varied surfaces that you will encounter during RC driving sessions.
• Directional tread pattern — The tread has been specifically designed to run quieter than traditional off-road tyres, which means less noise pollution during your driving sessions whilst maintaining excellent traction in all conditions.
• Thick centre carcass construction — The robust internal structure prevents ballooning at high speed, which is critical when you are pushing your brushless RC monster truck to its limits and need absolute confidence in your tyres' ability to maintain shape and grip.
• Pre-assembled and factory-glued — Save hours of tyre gluing frustration by receiving these wheels completely ready to install; the tyres are permanently bonded to the wheels using Traxxas' professional gluing process, guaranteeing reliability from the moment you fit them.
• Matte black X-Maxx wheels — These premium wheels feature a distinctive matte black finish that looks professional and aggressive whilst maintaining perfect visual balance with any truck colour scheme you are running.
• Integrated foam inserts — The foam inserts are included and pre-fitted, providing proper tyre support and shape maintenance during aggressive cornering and high-speed runs, preventing deformation that would compromise handling.
• 24mm splined hex fitting — Universal compatibility with Traxxas X-Maxx and XRT models means these wheels bolt straight onto your truck's front or rear axles without any modification or additional hardware.
• Front and rear compatibility — These wheels are designed to work equally well on both front and rear positions, giving you flexibility in your setup configuration and allowing you to rotate tyres for even wear.

Technical Performance

The Traxxas TRX7877 wheel and tyre package represents premium engineering designed specifically for 1/7 scale high-performance RC vehicles. The 7.4" x 4.0" Gravix race tyres are constructed with a thick centre carcass that prevents the ballooning effect that can occur when pushing your brushless RC truck to maximum speed. This engineering detail is crucial for maintaining predictable handling and grip, especially during competitive racing or extreme off-road driving. The directional tread pattern has been optimised through extensive testing to deliver excellent traction whilst running significantly quieter than conventional off-road tyres, meaning you can enjoy longer driving sessions without the excessive noise that typically accompanies aggressive tyre designs. The matte black X-Maxx wheels are manufactured to Traxxas' strict tolerances and pair perfectly with the Gravix tyres to create a balanced package that works across both stadium and truggy class applications. The 24mm splined hex fitting is the standard connection point for Traxxas X-Maxx and XRT models, providing a secure and reliable interface that ensures your wheels stay firmly attached during the most demanding driving conditions. The pre-fitted foam inserts serve a critical function in maintaining tyre shape and providing structural support during aggressive cornering and acceleration, preventing the sidewall deformation that would otherwise compromise handling and traction. Whether you are driving an X-Maxx Belted 4WD Brushless RTR in any colour variant (red, green, blue, orange) or an XRT VXL-8S, these wheels are engineered to deliver consistent performance lap after lap.

Frequently Asked Questions

• What vehicles are compatible with the TRX7877 wheels and tyres? — These wheels fit any Traxxas model with 24mm splined hex fittings, including the X-Maxx Belted 4WD Brushless RTR in red, green, blue or orange variants, the X-Maxx Ultimate in green or blue, the XRT VXL-8S in blue, green, orange or black, and the XRT Ultimate in green or blue. Compatibility is confirmed for both front and rear axle positions on these models.
• Are these tyres suitable for track racing? — Yes, absolutely. The Gravix race tyres are specifically engineered for track use and deliver the kind of consistent grip and performance that competitive drivers demand. The low-profile design and directional tread pattern make these an excellent choice for racing applications.
• Do I need to glue these tyres to the wheels myself? — No, these come completely pre-assembled and factory-glued by Traxxas, meaning they are ready to bolt straight onto your truck without any additional work. This saves significant time and guarantees a professional gluing job.
• What is the advantage of the thick centre carcass? — The thick centre carcass prevents ballooning, which is the outward deformation of the tyre wall that occurs under speed and cornering forces. By preventing this, the tyres maintain consistent shape and grip, delivering more predictable handling and better overall performance, especially during competitive racing.
• Can I use these on different Traxxas models with 24mm hex fittings? — Yes, these wheels will fit any Traxxas vehicle featuring 24mm splined hex wheel mounting, though they are specifically optimised for the X-Maxx and XRT platforms which represent the 1/7 scale and truggy class categories.
• Why are these tyres quieter than traditional off-road tyres? — The directional tread pattern has been engineered to reduce noise generation whilst maintaining excellent traction. This design reduces the aggressive noise that typically comes from standard off-road tyre patterns, making them more suitable for extended driving sessions without disturbing others.
• Are these suitable for beginners? — These are replacement wheels and tyres designed for existing Traxxas X-Maxx or XRT owners who want to upgrade their setup. If you are completely new to RC cars, you would typically purchase a ready to run RC truck complete with wheels, tyres and all electronics. However, if you already own a compatible truck, these are straightforward to install.
• What is the difference between Gravix race tyres and other Traxxas tyre options? — Gravix race tyres are specifically engineered for track and competitive use, featuring a low-profile design, directional tread pattern, and thick centre carcass to prevent ballooning. They run quieter than traditional off-road tyres and deliver excellent traction, making them ideal for drivers who want professional-grade performance. Other Traxxas options like Maxx AT or Sledgehammer tyres are designed for different driving styles and terrain types.
