Key Features
- Semi-Slick Tread Design — The semi-slick pattern maximises grip on asphalt and smooth surfaces, allowing you to corner faster and maintain control during aggressive riding manoeuvres that would be impossible with standard off-road tyres.
- S3 (Soft) Long-Wear Compound — Moulded in Pro-Line's renowned S3 soft compound, these tyres provide exceptional grip longevity and maintain their performance characteristics across multiple riding sessions without degrading rapidly like cheaper alternatives.
- High-Quality Closed Cell Foam Insert — The closed cell foam inserts included inside the tyres ensure consistent handling over varied surfaces and extend the lifespan of the tyre by preventing delamination and structural failure that can occur with worn or low-quality inserts.
- Pre-Glued Convenience — These tyres arrive already glued to the wheels, eliminating the need for messy glue applications, adhesive curing time, or the risk of improper installation that amateur builders often encounter.
- Black Supermoto Wheel — The black Supermoto-style wheel delivers authentic street bike aesthetics and features a smaller diameter than stock PROMOTO-MX wheels, creating that unmistakable scaled Supermoto silhouette that turns heads at any RC track or meet.
- Direct Fit Installation — Engineered as a perfect match for the Losi PROMOTO-MX rear position, this tyre requires no modifications, adapters, or compatibility workarounds—simply swap it in and ride.
- USA Manufacturing — Manufactured and assembled in the United States, you're investing in quality control standards and craftsmanship that rival production standards of major RC manufacturers.
- Optimal for Street and Track Surfaces — Whether you're running on asphalt tracks, smooth driveways, car parks, or clean street surfaces, the Supermoto S3 tyre excels where standard off-road motorcycle tyres would slip and slide.
Technical Performance
The Pro-Line 1/4 Supermoto S3 Motorcycle Rear Tyre represents a significant performance upgrade for PROMOTO-MX owners seeking improved street and track capability. Measuring 5.78 inches (147 millimetres) in product height with a width of 1.49 inches (38 millimetres), this rear tyre is precisely dimensioned to maintain authentic proportions whilst delivering the contact patch necessary for maximum grip. The inner diameter is specified at 3.9 inches, ensuring perfect compatibility with PROMOTO-MX rear hubs. The tyre features an inner diameter specification optimised for the motorcycle's rear axle assembly, guaranteeing secure mounting without slippage or play. Built from Pro-Line's S3 soft compound—the same durable formulation used in their professional racing programmes—this tyre maintains its grip characteristics across temperature variations and extended use. The closed cell foam insert construction represents the pinnacle of tyre insert technology, preventing the common issue of loose inserts that cause inconsistent handling in budget alternatives. Unlike tyres with basic open-cell or hollow inserts, the closed cell design maintains structural integrity and consistent damping characteristics throughout the tyre's service life. The semi-slick tread pattern is engineered for maximum contact patch on smooth surfaces, increasing grip coefficients on asphalt, concrete, and sealed surfaces where traditional off-road motorcycle tyre treads would be counter-productive. The pre-glued assembly means you receive a finished product that has undergone Pro-Line's quality control processes, ensuring consistent glue coverage and proper bead seating from the moment it arrives at your door.

Frequently Asked Questions
- Will the Pro-Line Supermoto S3 rear tyre fit my Losi PROMOTO-MX motorcycle? — Yes, this tyre is engineered as a direct fit for the Losi PROMOTO-MX rear position. It requires no modifications, adapters, or compatibility adjustments. Simply remove your existing rear tyre and wheel assembly and install the Supermoto tyre in its place. It's compatible with all PROMOTO-MX variants including the FXR, Club MX, and Supermoto models.
- What surfaces are these Supermoto tyres best suited for? — These semi-slick tyres are optimised for asphalt, concrete, sealed driveways, car parks, and other smooth hard surfaces. They provide superior grip compared to standard off-road motorcycle tyres on these surfaces, allowing for faster cornering and more precise control. Whilst they can function on grass or dirt, they are engineered specifically for street and track use where smooth surfaces are available.
- How do the Supermoto tyres compare to standard PROMOTO-MX off-road tyres? — The fundamental difference lies in tread pattern and application focus. Supermoto tyres feature a semi-slick design that maximises contact patch on smooth surfaces, whereas standard off-road motorcycle tyres use aggressive tread patterns designed for grip on loose or uneven terrain. Supermoto tyres deliver noticeably improved cornering ability, faster lap times on asphalt, and the authentic visual appeal of a street-focused motorcycle. They are not suitable for muddy, sandy, or heavily textured surfaces where off-road tyres would outperform them.
- Do I need to purchase both front and rear Supermoto tyres for best performance? — Whilst this rear tyre will provide immediate performance improvement on its own, Pro-Line recommends pairing it with the matching Supermoto Front tyre (PRO1022210) for the complete transformation of your PROMOTO-MX. Using matched front and rear Supermoto tyres ensures consistent handling characteristics, balanced grip distribution, and the full visual impact of the Supermoto conversion. Using only the rear tyre will provide handling improvement but may result in slight understeer due to the front tyre still featuring standard off-road characteristics.
- What is the S3 (Soft) compound, and why does it matter? — S3 (Soft) is Pro-Line's designation for a softer rubber formulation that prioritises grip over tyre lifespan. Compared to harder compounds (such as M3 medium or H3 hard), the S3 soft compound offers superior grip on asphalt surfaces, improved cornering traction, and more responsive handling characteristics. The trade-off is slightly faster wear during intensive use, but for most RC enthusiasts riding on smooth surfaces, the performance benefits vastly outweigh the minor durability reduction.
- Are the Supermoto tyres pre-glued, and can I re-glue them if needed? — Yes, these tyres arrive completely pre-glued to the black Supermoto wheel and are ready to install immediately. The glue bond is permanent under normal riding conditions. However, if you ever need to remove the tyre for replacement or repair, you can carefully separate the bead using appropriate tools and apply new tyre glue for reinstallation. Most users will never need to perform this procedure during the tyre's working life.
- What wheel colour options are available for the Supermoto S3 rear tyre? — The Supermoto S3 rear tyre comes mounted on a black Supermoto wheel. This black finish complements the street bike aesthetic and coordinates with most PROMOTO-MX colour schemes. The black wheel is the standard offering from Pro-Line for this application.
- How does the smaller wheel diameter affect the appearance and handling of my PROMOTO-MX? — The Supermoto wheel features a smaller diameter than stock PROMOTO-MX wheels, which creates the distinctive proportions of a full-scale Supermoto street bike. Visually, this lowers the apparent stance and gives your motorcycle that genuine street-focused silhouette. From a handling perspective, the smaller diameter can slightly affect gearing ratios and acceleration characteristics compared to stock wheels, though the pre-glued, performance-optimised tyre design compensates for this with improved grip and control.
- Is this suitable for beginners? — Yes, the Supermoto S3 rear tyre is suitable for riders of all experience levels. The pre-glued design means beginners don't need to handle messy glue applications, and the improved grip on asphalt makes the motorcycle more controllable and forgiving than standard off-road motorcycle tyres. Experienced riders will appreciate the performance upgrade and street-focused handling characteristics.
- Where is the Pro-Line Supermoto S3 tyre manufactured? — These tyres are proudly manufactured and assembled at Pro-Line Headquarters in the United States, ensuring strict quality control standards and consistent product quality across every unit produced.
