TRX9670

Overview

The Traxxas Tyres, Sledgehammer (2) / foam inserts (2) TRX9670 are ultra-rugged replacement tyres designed to deliver extreme traction and control across a variety of off-road terrain. Whether you're a serious RC enthusiast looking for the best performance from your 1:8 scale truggy or stadium truck, or you're exploring the world of RC cars UK and want dependable, high-grip tyres, the Sledgehammer range represents Traxxas's commitment to excellence in RC performance. These 3.8" diameter tyres provide the additional ground clearance and traction that serious RC bashers demand, making them an essential upgrade for anyone running a compatible RC truggy or stadium truck model.

If you're running a Traxxas Sledge Belted 1:8 4WD brushless RC monster truck, you'll know that tyre choice directly impacts handling, speed, and control in competition or recreational bashing. The Sledgehammer tyres have been engineered to maximise grip in the loosest surfaces whilst maintaining stability on harder-packed terrain. They're included as a pair with foam inserts, meaning you get everything needed for immediate installation and use. For RC enthusiasts in the UK seeking professional-grade replacement tyres for their brushless RC truck, these Sledgehammers deliver the performance and durability expected from a brand as established as Traxxas.

Sold as a complete pair with foam inserts included, this TRX9670 product represents genuine Traxxas parts engineered to exact specifications for maximum compatibility and reliability. Whether you're replacing worn tyres on an existing truck or upgrading from standard rubber, the Sledgehammer tyres offer measurable improvements in traction and debris clearing that translate directly to faster lap times and more confident control in challenging conditions.

Key Features

• Ultra-Rugged Construction — The Sledgehammer tyres are built with extreme traction and control as their primary design goal, meaning every element of the tyre compound and tread pattern has been optimised for maximum grip across varied off-road surfaces. This rugged construction ensures the tyres withstand aggressive bashing and competitive racing without premature wear.
• Increased Overall Diameter (3.8 inches) — The larger 3.8" wheel diameter compared to standard tyres provides additional ground clearance, allowing your RC truck to navigate obstacles, ruts, and uneven terrain with greater ease. Extra ground clearance is crucial for preventing belly scraping and improving overall vehicle geometry in technical courses.
• Open Block Tread Design — Unlike closed or directional tread patterns, the Sledgehammer's open block design is specifically engineered to clear mud, loose soil, grass, and debris from the tyre contact patch. This self-cleaning action prevents clogging and maintains consistent traction in loose surfaces where mud and dirt build-up would otherwise reduce grip.
• Unmatched Traction in Loose Surfaces — The combination of the open block tread pattern, rugged construction, and increased diameter delivers unmatched traction specifically optimised for loose terrain including sand, dirt, gravel, and muddy conditions. This makes Sledgehammer tyres ideal for outdoor RC tracks and natural terrain.
• Foam Inserts Included — Each pair of tyres comes with foam inserts pre-assembled, providing immediate plug-and-play readiness. Foam inserts absorb impacts, reduce vibration, and provide a degree of sidewall support that is essential for maintaining tyre shape during aggressive cornering and high-speed runs.
• Sold as a Pair — This product includes two complete tyres with inserts, giving you a matched front or rear set (or suitable for any axle depending on your setup requirements). Having a matched pair ensures consistent handling characteristics across both wheels.

Technical Performance

The Sledgehammer tyres represent professional-grade engineering designed for 1:8 scale truggy and stadium truck platforms. Measuring 3.8" in overall diameter, these tyres integrate a proven open block tread pattern that has been refined through extensive testing on competitive RC circuits and recreational bashing courses throughout the UK and beyond. The tyre compound itself is formulated to provide consistent grip across a temperature range whilst resisting premature degradation from UV exposure and aggressive use. The foam inserts supplied with each pair are engineered to the exact specifications required by Traxxas chassis geometry, ensuring proper sidewall support without causing handling inconsistencies. The inserts work in conjunction with the tyre's construction to absorb energy from impacts with roots, rocks, and uneven ground whilst maintaining predictable traction delivery to the chassis. Built to the exacting standards Traxxas demands, these tyres are compatible with the full Traxxas Sledge Belted 1:8 4WD brushless RC truck range across all colour variants (Blue, Orange, Green, and Red). The engineering focus on debris clearance and traction in loose terrain makes these tyres particularly valuable for venues with unprepared or naturally variable track surfaces.

Frequently Asked Questions

• Which RC trucks are these tyres compatible with? — The Traxxas Sledgehammer tyres TRX9670 are designed for 1:8 scale truggy and stadium truck platforms. They are specifically compatible with the Traxxas Sledge Belted 1:8 4WD brushless RC monster truck range, including the blue, orange, green, and red colour variants (model numbers TRX95096-4-BLUE, TRX95096-4-ORNG, TRX95096-4-GRN, and TRX95096-4-RED respectively). Before purchasing, verify that your RC truck accepts 3.8" diameter tyres to ensure proper fitment.
• What is the advantage of the open block tread design? — The open block tread pattern on Sledgehammer tyres actively clears mud, dirt, grass, and debris from the tyre contact patch as you drive, a property known as self-cleaning. This prevents material from building up on the tyre surface, which would reduce grip. In loose terrain and muddy conditions, this design delivers unmatched traction compared to closed or directional tread patterns that allow debris accumulation.
• Do I need to replace the foam inserts? — The foam inserts supplied with the TRX9670 are engineered to work in perfect harmony with the Sledgehammer tyre design and your truck's suspension geometry. They should be retained when replacing only the tyre rubber. Foam inserts typically last considerably longer than rubber tyres and should only be replaced if visibly damaged or compressed beyond recovery. For replacement inserts, consult Traxxas spare parts catalogues or contact RC Model Shop for guidance.
• What is the difference between these and standard Traxxas tyres? — The Sledgehammer tyres feature a larger 3.8" diameter (compared to some standard options) combined with the unique open block tread design optimised for loose terrain. This combination delivers greater ground clearance, more aggressive self-cleaning action, and superior traction in muddy or sandy conditions. They represent Traxxas's performance-focused tyre option for serious bashers and competitive drivers seeking maximum traction in challenging off-road conditions.
• Are these tyres suitable for paved surfaces? — Sledgehammer tyres are optimised for off-road loose terrain including dirt, sand, mud, and gravel. Whilst they will function on harder surfaces, they are not specifically engineered for tarmac or concrete, and grip may be reduced compared to road-specific tyre designs. For mixed-surface use, consider whether your primary driving will be off-road before committing to Sledgehammer tyres.
• How long do these tyres typically last? — Tyre lifespan depends on driving style, surface conditions, maintenance, and frequency of use. Aggressive bashing on rocky terrain will reduce tyre life compared to smoother dirt track use. Regular cleaning after muddy driving sessions will extend tyre longevity by preventing premature rubber degradation. Replace tyres when tread depth reduces noticeably or when the rubber becomes visibly hard and glossy, indicating a loss of grip.
