These dBoots Fortress MT Tire and Inserts provide optimum performance on a wide range of surfaces.
Overview
The ARRMA Fortress MT Tire 2.8 Foam Inserts (2) Z-AR520045 are premium replacement tyres designed specifically for 1/10 scale RC trucks, offering exceptional performance across a wide variety of off-road surfaces. Whether you're bashing through muddy tracks, tackling rocky terrain, or tearing across sandy ground, these dBoots Fortress MT tyres deliver the traction and durability you need to keep your RC truck performing at its best. As a UK RC hobbyist, you'll appreciate how these tyres are engineered to work seamlessly with popular 1/10 scale platforms, making them an ideal upgrade or replacement set for models like the ARRMA Granite and other similar trucks in the RC car UK market.
These aren't just any off-road tyres – they represent a significant investment in your RC vehicle's handling characteristics and longevity. The Fortress MT range has earned its reputation among serious RC enthusiasts for delivering consistent grip in both wet and dry conditions, whilst maintaining the structural integrity needed for aggressive driving. If you're running a brushless RC truck or any high-performance 1/10 scale monster truck, swapping to quality tyres like these can transform your driving experience and give you the confidence to tackle more challenging terrain.
The package includes everything you need: two ready-to-install Fortress MT tyres paired with two medium-compound foam inserts. This combination is crucial because the foam inserts work in harmony with the tyre carcass to absorb impacts, maintain sidewall stiffness, and provide the responsive handling that separates casual bashers from serious RC enthusiasts. Whether you're looking to refresh your current setup or build out a complete ready to run RC truck, the ARRMA Fortress MT tyres represent a smart investment in performance and reliability.
Key Features
- Aggressive Tread Pattern — The Fortress MT design incorporates a highly aggressive tread pattern specifically engineered to bite into loose surfaces and provide excellent traction on all off-road terrain types, from mud and sand to gravel and rocky ground, ensuring your RC truck maintains grip in even the most challenging conditions.
- Medium Compound Foam Inserts — Each tyre set includes two genuine medium-compound foam inserts that work with the tyre carcass to optimize sidewall flex, improve handling response, and protect the internal structure from impacts during aggressive driving and high-speed runs.
- Durable Material Compound — The Fortress MT tyres are constructed from a durable rubber compound specifically formulated to withstand extended use whilst resisting wear from rough terrain, ensuring these tyres will deliver consistent performance over many hours of driving without significant degradation.
- Wide Tread Blocks — The broad tread block design maximizes contact patch area on uneven surfaces, which translates to improved traction, better power delivery from your RC truck's motor, and more stable handling during cornering and acceleration.
- 1/10 Scale Compatibility — With a 2.8 inch (72mm) diameter, these tyres are purpose-built for 1/10 scale truck platforms, ensuring perfect fitment and optimal performance without modification or adapter requirements.
- Front and Rear Use — These tyres are suitable for both front and rear positions, giving you flexibility in your tyre rotation and maintenance strategy, and allowing you to purchase a single set that covers both axles if needed.
Technical Performance
The ARRMA Fortress MT Tire represents the culmination of years of off-road RC engineering expertise. At 2.8 inches (72mm) in bead diameter with a 4.9 inch (125mm) outer diameter and 2.8 inch width, these tyres are precisely engineered to fit 1/10 scale trucks without any modifications. The combination of the aggressive tread pattern and the included medium-compound foam inserts creates a comprehensive suspension and traction system. The foam inserts are not simply packaged as an afterthought – they're integral to the tyre's performance characteristics. Medium-compound foam offers the optimal balance between responsiveness and durability for general-purpose off-road driving; softer compounds provide better grip but wear quickly, whilst harder compounds last longer but sacrifice traction. The durable rubber compound used in the Fortress MT carcass is formulated to resist the abrasive effects of rocks, dirt, and sharp terrain features that would quickly degrade lower-quality tyres. The engineering behind the aggressive tread pattern focuses on maximizing the number and size of tread blocks that contact the ground simultaneously, which dramatically improves traction on loose surfaces. Whether you're running a brushless RC truck with modern high-output motors or a brushed system, these tyres deliver the mechanical grip needed to translate that power into forward motion without excessive wheelspin.

Frequently Asked Questions
- Are these tyres suitable for all types of off-road RC trucks? — The Fortress MT tyres are designed for 1/10 scale trucks and work excellently on a wide variety of surfaces including mud, sand, gravel, and rocky terrain. They're compatible with any 1/10 scale truck platform that accepts 2.8 inch diameter tyres, including ARRMA models like the Granite, and many other popular ready to run RC trucks available in the UK market.
- What makes the foam inserts so important? — Foam inserts are absolutely critical to tyre performance. They control how much the tyre sidewall flexes, which directly affects handling precision, durability, and how well the tyre maintains its shape under cornering loads. The medium compound included with these Fortress MT tyres is specifically chosen to provide the best all-around balance for recreational and competitive driving without requiring constant adjustment.
- How long will these tyres last? — The durable rubber compound is engineered for extended use, but tyre life depends on your driving style and terrain. Aggressive bashing on extremely rocky terrain will wear tyres faster than moderate driving on sandy areas. Most users find that properly maintained Fortress MT tyres provide excellent value over 10-20 hours of driving time before requiring replacement.
- Can I use these tyres without the foam inserts? — Technically you could remove the foam inserts, but this is not recommended. The tyre carcass is engineered as a system with the foam insert; without them, you'll experience excessive sidewall flex, poor handling response, and the tyre will be more susceptible to damage from impacts and rough terrain.
- Are these tyres waterproof for wet conditions? — Yes, like all rubber RC tyres, the Fortress MT construction is inherently water-resistant. The aggressive tread pattern actually provides excellent traction in wet conditions because the tread blocks are designed to channel water away from the contact patch and bite into soft, muddy terrain.
- What is the difference between these and other 2.8 inch tyres for RC trucks? — The Fortress MT designation indicates the specific tread pattern and compound formulation developed by dBoots through extensive testing. The aggressive tread blocks, combined with the medium-compound foam inserts, provide superior all-surface performance compared to budget alternatives, and the durable material compound means you'll get more driving hours before replacement becomes necessary.
