Overview
The PRO 1/4 Pro-Spec V2 Bead Rear Tire Mounting Sleeves are essential replacement components for serious RC motorcycle enthusiasts running the Losi Promoto-MX platform. These mounting sleeves are specifically designed to work with Pro-Line V2 Bead MX tyres, providing a secure and reliable interface between your premium RC tyres and Pro-Spec Aluminium Wheels. Whether you're a competitive racer looking to optimise your Promoto-MX setup or a weekend basher who wants to experiment with different tyre compounds and tread patterns, these sleeves give you the flexibility to swap tyres quickly and efficiently without compromising grip or handling characteristics.
If you're serious about RC motorcycle racing in the UK, you'll appreciate how these mounting sleeves streamline your tyre management workflow. Rather than struggling with traditional glued-on tyres that can be problematic to remove, these sleeves offer a hybrid approach: they provide a robust glue bond for racing reliability, but they're engineered to make tyre changes straightforward when you need to switch compounds for different track conditions. This is particularly valuable if you're running multiple sets of MX tyres for different weather or track surface conditions, or if you simply want to rotate your tyres more frequently to maintain consistent performance across your RC car collection.
The sleeves feature intelligent locating geometry that ensures perfect alignment every time you install them onto your Pro-Spec Aluminium Wheels, eliminating the guesswork and potential for misalignment that can compromise handling. This attention to engineering detail is what you'd expect from Pro-Line Racing, a manufacturer renowned for producing competition-grade RC components that satisfy the demands of serious racers and dedicated hobbyists alike. These are genuine OEM replacement parts that maintain the integrity of your Promoto-MX setup.
Key Features
- Robust and Reliable Glue-Bond Construction — The sleeves are engineered to accept a secure adhesive bond with your Pro-Line V2 Bead MX tyres, ensuring that your rubber stays firmly attached during high-speed racing, aggressive cornering, and demanding track conditions that would challenge inferior tyre mounting solutions.
- Convenient Glueless Tyre Changing Capability — Despite their glue-bond design, these sleeves are engineered to allow tyre removal and replacement without the frustration and mess associated with permanently bonded tyres, making it practical to rotate through multiple tyre compounds during a race day or testing session.
- Locating Features for Easier Screw Installation and Alignment — The integrated locating geometry on these sleeves guides the fasteners into perfect alignment with your Pro-Spec Aluminium Wheels every time, eliminating potential misalignment issues that could cause vibration, uneven tyre wear, or handling problems that would slow your lap times.
- Compatibility with Pro-Line V2 Bead MX Tyres — These sleeves are specifically engineered to work seamlessly with Pro-Line's V2 Bead MX tyre range, ensuring that you benefit from perfect fitment and optimal performance from this premium tyre compound and tread pattern combination.
- Designed for Pro-Spec Aluminium Rear Rims — The sleeves mount directly onto Pro-Spec Aluminium Wheels, which are the professional-grade wheels used by competitive racers who demand minimal unsprung weight and maximum reliability.
Technical Performance
These Pro-Spec V2 Bead Rear Tire Mounting Sleeves represent the engineering philosophy that Pro-Line Racing brings to every component they manufacture. The sleeves are precision-engineered to tight tolerances, ensuring that they mate perfectly with both Pro-Spec Aluminium Wheels and Pro-Line V2 Bead MX tyres without any play, slop, or misalignment that could introduce inconsistency into your handling balance. The glue-bond design provides the security and reliability demanded by competitive racing, where tyre separation mid-race would be catastrophic, yet the sleeves are engineered for practical tyre changes, allowing serious hobbyists to experiment with different compounds and tread patterns without significant downtime. The locating features incorporated into the sleeve design ensure that screw installation is intuitive and repeatable, eliminating the potential for human error that could compromise wheel balance or cause vibration at speed. These are genuine OEM components manufactured by Pro-Line Racing, a company with decades of experience in developing high-performance RC components. The sleeves work exclusively with the Losi 1/4 Promoto-MX motorcycle platform and are compatible across all Promoto-MX variants, including the RTR models with Battery and Charger included, Club MX edition, and FXR edition variants.

Frequently Asked Questions
- Are these Pro-Spec V2 mounting sleeves compatible with all Promoto-MX models? — Yes, these sleeves are compatible with all Losi 1/4 Promoto-MX variants, including the RTR models with Battery and Charger, the Club MX edition in blue, and the FXR edition in red. They work with any Promoto-MX platform that accepts Pro-Spec Aluminium Wheels.
- What tyres do these sleeves work with? — These mounting sleeves are engineered exclusively for Pro-Line V2 Bead MX tyres. Pro-Spec Aluminium Wheels work only with Pro-Line V2 Bead MX tyres, so it's essential to use the correct tyre type to ensure proper fitment, balance, and handling performance.
- Do I need to glue these sleeves to the wheels? — No, the sleeves are the component that glues to your MX tyres. You glue your Pro-Line V2 Bead MX tyre to the mounting sleeve, and then the assembly mounts to your Pro-Spec Aluminium Wheel using the locating features and fasteners. This hybrid design gives you the reliability of a glued tyre with the convenience of being able to change tyres when needed.
- Will these mounting sleeves improve my Promoto-MX handling? — While mounting sleeves themselves don't directly improve handling, using quality Pro-Spec components ensures that your tyre mounting is consistent, reliable, and properly aligned. Poor tyre mounting can introduce vibration and instability, so upgrading to genuine Pro-Line sleeves ensures optimal performance from your racing setup.
- Are these sleeves difficult to install? — The sleeves feature integrated locating geometry specifically designed to make installation straightforward and foolproof. The locating features guide your fasteners into perfect alignment, eliminating guesswork and ensuring that installation is consistent every time, even for riders who are new to working with Pro-Spec components.
- Why should I buy genuine Pro-Line mounting sleeves rather than generic alternatives? — Pro-Line Racing manufactures these sleeves to precision tolerances that ensure perfect fitment with Pro-Spec Aluminium Wheels and Pro-Line V2 Bead MX tyres. Generic or knockoff alternatives may have inferior tolerances, leading to play, misalignment, and inconsistent handling that compromises your competitive performance.
- How long do these mounting sleeves last? — These are durable components manufactured to professional standards. Their lifespan depends on usage intensity and whether you rotate your tyres regularly. For dedicated racers who change tyres frequently, these sleeves will provide years of reliable service.
