TRX3778

Overview

The Traxxas Sledgehammer Tyres Mounted on 2.8in Black Wheels (TRX3778) represent a premium wheel and tyre solution for serious RC enthusiasts in the UK. These are genuine Traxxas replacement wheels and tyres, pre-assembled and factory-glued, delivering the ultimate in convenience and performance for your 1/10 scale electric RC truck. Whether you're upgrading an existing model or replacing worn tyres on your current setup, these wheels bring immediate performance improvements to models like the BIGFOOT No. 1, Rustler VXL, and Stampede VXL. If you're shopping for an RC car in the UK and want genuinely superior off-road capability, these Sledgehammer tyres are specifically engineered to deliver maximum traction and control across a variety of challenging terrain.

Sledgehammer tyres have become the benchmark for extreme-terrain performance in the RC truck world. The Traxxas design philosophy behind these tyres focuses on delivering unmatched traction in loose surfaces whilst maintaining excellent control at high speeds. The open block tread design actively clears mud and debris as you drive, preventing the kind of clogging that can occur with other tyre designs and reducing weight that would otherwise slow your truck. The tall sidewall profile provides additional ground clearance, which is essential when tackling rough, uneven terrain or steep obstacles. Combined with tough 2.8-inch black 5-spoke wheels, you get a complete, ready-to-bolt-on solution with no additional setup required.

These are TSM-rated wheels and tyres, meaning they have been tested and approved for high-speed applications. Traxxas TSM (Traction Control System) rating ensures that this tyre and wheel combination will perform reliably at the speeds your electric truck is capable of producing. The fact that they come pre-glued and assembled means you simply remove them from the box, bolt them onto your 12mm hex hubs, and you're ready to drive immediately. For anyone serious about off-road RC performance in the UK market, these represent genuine value and reliability backed by Traxxas' reputation for quality.

Key Features

• Sledgehammer Extreme-Terrain Tyres — The Sledgehammer is Traxxas' premium off-road tyre design, engineered specifically to provide maximum traction and control across a wide variety of off-road surfaces from loose dirt and sand to rocky terrain and mud. The open block tread pattern is purposefully designed to clear mud and debris as you drive, preventing tyre clogging that would otherwise reduce grip and increase weight, whilst the aggressive compound delivers superior grip on every surface type.
• Tall Sidewall Design for Enhanced Ground Clearance — The Sledgehammer's distinctive tall sidewall profile provides measurably more ground clearance than conventional tyre designs, allowing your truck to traverse rough, uneven terrain, navigate over larger rocks and obstacles, and maintain control on challenging uphill climbs without risk of the body or chassis bottoming out on the ground.
• Pre-Mounted and Factory-Glued — These wheels and tyres arrive completely assembled and glued, eliminating the time-consuming and often messy process of mounting and gluing tyres yourself. This factory precision ensures consistent glue application and perfect bead seating, delivering reliable performance from the moment you bolt them on.
• Tough 2.8-Inch Black 5-Spoke Wheels — The 2.8-inch diameter is the standard size for 1/10 scale truck models, whilst the black multi-spoke wheel design provides an aggressive appearance and reliable strength. The 5-spoke design balances light weight with structural rigidity, preventing deformation under the extreme forces generated during high-speed driving and rough terrain bashing.
• Foam Inserts Included — Foam inserts are factory-installed inside each tyre, serving the crucial function of providing sidewall support and maintaining tyre shape during hard cornering and aggressive driving. The foam prevents the tyre from rolling or deforming excessively, which would cause loss of traction and unpredictable handling characteristics.
• 12mm Hex Fitment for Electric Rear — These wheels are specifically designed for the rear axle of 2WD electric RC trucks and are fitted with industry-standard 12mm hexagonal drive adapters, making them compatible with a wide range of Traxxas models including the Rustler, Stampede, and BIGFOOT replicas. The electric rear designation means they are engineered for the torque characteristics and weight distribution of electric-powered vehicles.
• TSM-Rated for High-Speed Performance — TSM rating from Traxxas indicates these wheels and tyres have been extensively tested and approved for use in high-speed applications, ensuring they will maintain structural integrity, grip, and reliability even when your truck is running at maximum velocity. This rating provides confidence that you're using components tested to perform under real-world driving demands.
• Direct Replacement and Upgrade Solution — These wheels and tyres are designed as direct replacements for original equipment on compatible Traxxas models, but they also function as a significant performance upgrade when fitted to any compatible 1/10 scale truck with 12mm hex rear axles. Upgrading to Sledgehammer tyres can transform the off-road capability of your vehicle.

Technical Performance

The Traxxas Sledgehammer tyre is a masterclass in off-road tyre engineering. The open block tread design is far more sophisticated than it appears at first glance; the large, blocky tread elements are specifically spaced to provide edge-to-edge contact with the ground surface, maximising the number of grip points whilst maintaining the structural integrity of the tread itself. This design principle delivers exceptional bite on loose surfaces like sand, dirt, and gravel, where conventional road-biased tyres would simply spin and dig in uselessly. The high-grip rubber compound used in Sledgehammer tyres is formulated with a specific hardness that provides excellent traction whilst wearing at a reasonable rate, balancing ultimate performance with durability. The tall sidewall is not merely cosmetic; it flexes and deforms more readily than a short-sidewall tyre, allowing the tyre to conform to uneven terrain and maintain contact over rocks and obstacles. This characteristic is particularly valuable in rock crawling applications and when driving over highly technical terrain. The 2.8-inch wheel diameter is optimised for 1/10 scale trucks, providing the correct rolling circumference to work with factory gearing and delivering appropriate ground clearance. The 5-spoke wheel design uses a multi-spoke geometry that distributes forces across the wheel rim efficiently, preventing the stress concentration that can occur with fewer spokes. The black finish provides a tough, corrosion-resistant appearance that maintains its appearance through countless hours of off-road driving and washing. Foam inserts are essential in modern RC racing and bashing; they provide progressive sidewall support, preventing the dramatic sidewall deformation that would otherwise occur under cornering forces, and they prevent the tyre from rolling off the rim under acceleration or braking.

Frequently Asked Questions

• What vehicles are these Sledgehammer wheels and tyres compatible with? — These wheels and tyres are specifically designed for the rear axle of electric 2WD vehicles and are compatible with any model featuring 12mm hex rear hubs. Direct applications include the Traxxas BIGFOOT No. 1 Officially Licensed Replica, Rustler VXL, and Stampede VXL, but they will fit any 1/10 scale truck or buggy with 12mm hex rear axles, making them a popular upgrade for owners of other RC truck models seeking improved off-road performance.
• Are these wheels and tyres suitable for beginners? — Yes, absolutely. Since these wheels and tyres are pre-assembled and factory-glued, they eliminate the technical challenge of mounting and gluing tyres, which is often frustrating and messy for beginners. Simply unbox them and bolt them on using a hex driver. However, beginners should note that Sledgehammer tyres are designed for serious off-road performance; if you're driving exclusively on pavement or smooth surfaces, alternative tyre designs may be more appropriate.
• Can I use these on the front axle as well as the rear? — These wheels and tyres are specifically engineered for electric rear fitment on 2WD vehicles. Front fitment is not recommended as the geometry and performance characteristics are optimised for rear-wheel use. For the front axle, you should use Traxxas' front tyre options designed specifically for front suspension geometry.
• What makes Sledgehammer tyres better than standard tyres? — The Sledgehammer design excels in extreme-terrain scenarios that would challenge conventional tyres. The open block tread pattern clears mud and debris rather than clogging with them, maintaining grip throughout your run. The tall sidewall provides superior ground clearance and allows the tyre to conform to uneven terrain better than short-sidewall alternatives. The high-grip rubber compound is specifically formulated for off-road surfaces. If you're primarily bashing on rough terrain, sand, gravel, or rocky surfaces, Sledgehammer tyres will deliver noticeably better performance than basic tyre designs.
• Are these tyres suitable for high-speed driving? — Yes, these wheels and tyres are TSM-rated, indicating Traxxas has tested and certified them for high-speed applications. The structural design is engineered to maintain integrity at maximum velocities, and the foam inserts prevent deformation under the forces generated during fast driving. You can confidently run these at top speed.
• Do these wheels and tyres come pre-glued? — Yes, these wheels and tyres are factory-mounted and factory-glued, which means they arrive completely ready to install. The glue application is precisely controlled in manufacturing, ensuring proper tyre seating and eliminating one of the most challenging aspects of RC maintenance.
• What is the wheel diameter and fitment? — These are 2.8-inch diameter wheels fitted with industry-standard 12mm hexagonal drive adapters, making them compatible with any RC truck or buggy using 12mm hex rear axles. The 2.8-inch size is the standard diameter for 1/10 scale vehicles.
