Overview
This is a Dunlop MX33 Rear Tire for the Losi® Promoto MX. Introducing Pro-Line’s first-ever licensed tire from Dunlop Motorcycle Tires: The MX33! This is a top choice of both pro and amateur motocross racers around the world, and now we’re bringing Dunlop’s legendary style and performance to the Losi® Promoto-MX RC dirt bike!
The MX33 delivers extraordinary handling in a wide range of soft-to-intermediate terrain types. It features beefed-up tread lugs over the stock MX53 tire, creating a super aggressive look on your dirt bike. We replicated Dunlop’s Multiple Block Distribution, which varies the height and angles of the tread lugs across the shoulders and center of the tire. This translates into a tire that bites into the dirt and propels your bike with unmatched forward traction and handling.
The MX33 is pre-mounted to Pro-Line’s black Bullyspoke V2 Bead style wheel, which has benefits in both durability and aesthetics. The spoke thickness has been increased to prevent bending on hard impacts. The beads overall have been brought in towards the center of the wheel, which creates a much more scale-looking tire profile that matches your real dirt bike. Included inside the tire is a high-quality, durable closed-cell insert.

Key Features
- Officially Licensed by Dunlop Motorcycle Tyres — This tyre uses authentic Dunlop branding and design, giving you genuine motocross performance technology rather than generic RC tyre alternatives, which matters to riders who want authenticity and proven engineering.

Technical Performance

The CR4 compound offers a firm rubber hardness ideal for balanced performance across varying terrain conditions typical of UK backyard tracks and natural riding areas.

The black Bullyspoke wheel construction features plastic material offering durability and low rotational mass for responsive handling. This all-terrain tyre is engineered for backyard and natural terrain use, delivering genuine traction improvements over standard equipment in soft dirt, sand, grass and mixed surfaces. The overall tyre and wheel assembly is engineered to work exclusively with the Losi 1/4 Promoto-MX range, ensuring perfect fitment and optimal performance characteristics specific to that platform's suspension geometry and riding dynamics.

Frequently Asked Questions
- What is the Dunlop Geomax MX33 and why is it special for RC motorcycles? — The MX33 is a genuine licensed tyre design from Dunlop Motorcycle Tyres, the same company that supplies tyres to professional motocross racers worldwide. Pro-Line has replicated this proven competition tyre design specifically for 1/4 scale RC motorcycles. What makes it special is that you get authentic motocross tyre performance—including the Multiple Block Distribution technology that varies tread lug height and angles—in a 1/4 scale format. This means significantly improved traction and handling compared to generic RC tyres, whether you're racing competitively or bashing for fun at your local RC track or backyard.
- Will this tyre fit my Losi Promoto-MX? — Yes, this is a rear tyre specifically designed for the Losi 1/4 Promoto-MX motorcycle series. It is compatible with the Promoto-MX FXR models, Pro Circuit RTR version, Club MX variant, and the Promoto-SM supermoto models. The tyre comes pre-mounted on the Bullyspoke wheel, so installation is straightforward—simply remove your existing rear wheel and install this unit. Always confirm your specific Promoto-MX model before ordering to ensure perfect fitment.
- What does the CR4 compound mean, and is it suitable for all terrains? — CR4 designates the tyre compound hardness—in this case, a firm rubber compound that balances grip with durability. The CR4 is designed for all-terrain use including soft dirt, sand, grass and mixed surfaces typical of backyard tracks and natural riding areas. This makes it versatile for both casual recreational riding and more serious competition use. If you're exclusively riding on very soft, wet terrain, you might want softer compounds; for hard-packed track, harder compounds might suit better. The CR4 represents an excellent middle ground for most UK riding conditions.
- Is the tyre pre-mounted and ready to use? — Yes, absolutely. The Dunlop MX33 tyre arrives pre-mounted on the black Bullyspoke V2 Bead wheel with the closed-cell insert already installed. You can install it directly onto your Promoto-MX rear axle without any additional assembly, mounting procedures, or tools. This saves time and eliminates potential fitment issues compared to buying tyres and wheels separately.
- What performance improvements will I see compared to stock tyres? — The MX33 features beefed-up tread lugs—thicker and more aggressive than the stock MX53 tyre—which bite into dirt with greater force, delivering superior forward traction. The Multiple Block Distribution technology creates varying tread lug heights and angles, optimising grip across the tyre's shoulders and centre for improved cornering response and acceleration traction. Riders typically report noticeably better grip in corners, more confident acceleration out of turns, and improved overall handling precision, particularly noticeable on softer terrain where the aggressive tread makes the most difference. The wider Glue Beads on the wheel also improve tyre mounting consistency, ensuring optimal tyre-to-ground contact.
- Are these tyres available as a pair or just individual rear tyres? — Please note that this listing is for a single rear tyre. If you need a complete matching pair for front and rear, you should also order the Pro-Line 1/4 Dunlop Geomax MX33 CR4 Front Tyre (model G-PRO1022910). The manufacturer recommends running matched tyre sets on both axles for balanced handling characteristics and consistent performance throughout the Promoto-MX's full platform.
- How durable is the Bullyspoke wheel, and what is the benefit of the V2 Bead design? — The Bullyspoke V2 wheel features thicker spokes specifically engineered to resist bending under the hard impacts typical of aggressive riding, jumps and rough terrain. The V2 Bead design brings the wheel beads inward toward the centre, creating a narrower tyre profile that looks more authentically proportioned to a genuine motocross bike wheel. This combination of durability and scale aesthetics means your Promoto-MX will look and perform like a proper miniature motocross motorcycle rather than a toy. The wider, flat glue beads also make any future tyre maintenance or replacement straightforward and consistent.
- Can I use this tyre on Promoto-SM Supermoto models? — Yes, the MX33 is confirmed compatible with both the Losi 1/4 Promoto-SM FXR Supermoto RTR and the Promoto-SM FXR Supermoto RTR Basic variants. The Supermoto models have the same wheel size and axle design as the standard Promoto-MX, so this rear tyre will fit perfectly. However, note that supermoto setups might benefit from the matching front tyre (G-PRO1022910) for balanced performance.
- What makes Pro-Line tyres a trusted choice for UK RC riders? — Pro-Line has been manufacturing RC tyres since 1982, giving them over four decades of expertise in RC tyre engineering and racing. They are authorised manufacturers trusted by serious RC competitors and casual enthusiasts alike. Their commitment to licensed designs (like this Dunlop partnership) ensures you get technology proven in real motorsport. Pro-Line is widely recognised across UK RC communities as delivering consistent quality, authentic designs, and performance that delivers results on tracks and backyards across the country.
- Is there a matching front tyre available? — Yes, Pro-Line manufactures a matching 1/4 Dunlop Geomax MX33 CR4 Front Tyre (model G-PRO1022910) designed specifically for the Promoto-MX and Promoto-SM platforms. Running matched MX33 tyres front and rear ensures consistent handling characteristics, balanced grip distribution, and optimal performance across your motorcycle's entire footprint.
