Key Features
- Semi-Slick Tread Design for Maximum Grip — The specially formulated semi-slick pattern grips asphalt and smooth surfaces with exceptional consistency, allowing you to carve sharper apexes and maintain precise control through technical sections. This tread design minimises rolling resistance on hard-packed surfaces whilst providing the bite you need for confident cornering and aggressive acceleration.
- S3 Soft Long-Wear Compound — Pro-Line's proprietary S3 soft compound offers superior grip that lasts, delivering consistent performance lap after lap without excessive wear. This premium rubber formulation maintains flexibility across temperature ranges, ensuring predictable handling whether you're riding in cool morning sessions or hot afternoon bashing.
- Thicker Carcass for Increased Tyre Life — Unlike thinner economy tyres, the Supermoto features reinforced sidewalls and a substantial carcass design that resists pinching, cutting, and premature wear. This robust construction means you'll replace these tyres less frequently, saving money whilst maintaining consistent handling characteristics throughout the tyre's lifespan.
- Cornering Sipes for Unmatched Handling — Precision-engineered sipes (small cuts) in the tread blocks improve edge grip during aggressive cornering, allowing you to pop better wheelies, maintain speed through technical turns, and execute manoeuvres with impressive precision. These sipes work in concert with the semi-slick design to deliver supermoto-authentic performance.
- Closed-Cell Foam Insert Included — High-quality foam inserts provide consistent handling and durability by absorbing impacts and preventing tyre roll whilst cornering. These purpose-designed inserts maintain their integrity through extended use, ensuring your Promoto-SM handles predictably session after session without the mushy feel of inferior foam.
- Premounted to Plastic Sleeve for Pro-Spec Wheel — This tyre arrives factory-mounted on a precision plastic sleeve, ready for immediate installation onto compatible Pro-Spec Aluminium wheels. The sleeve ensures perfect tyre-to-wheel alignment and eliminates assembly hassles, getting you on the track faster than ever.
- Easy Tyre Swaps to Pro-Spec Aluminium Wheel — When it's time to refresh rubber, the sleeve-mounted design allows quick, tool-free tyre changes. Simply slide off the worn tyre and sleeve, and slip on the new package—no tyre levers, no fighting with stubborn beads, just effortless maintenance that keeps you riding.
- Scale-Authentic Motorcycle Look — The Supermoto tyre delivers genuine visual realism that matches full-size motorcycle proportions and styling. Paired with Pro-Spec Aluminium wheels, this assembly creates a complete package that looks like a genuine supermoto motorcycle in miniature, perfect for scale builders and visual enthusiasts who appreciate authentic details.
- Made in the USA Since 1982 — Pro-Line's four decades of tyre manufacturing expertise is evident in every aspect of this product. Built at Pro-Line's dedicated USA headquarters using rigorous quality control, you're buying genuine American engineering and proven reliability that has earned respect from RC competitors and hobbyists worldwide.
Technical Performance
The Pro-Line 1/4 Supermoto S3 Front Tyre represents pinnacle engineering for quarter-scale supermoto RC motorcycles. At 4.0 inches outer diameter, this tyre is precisely scaled to complement the Losi Promoto-SM's proportions whilst delivering authentic motorcycle aesthetics. The tyre features a 1.18-inch (30mm) width, carefully calibrated to deliver the balance between cornering grip and straight-line stability that supermoto riding demands. The soft S3 compound is specifically formulated for the intermediate grip levels and forgiving characteristics that riders expect from premium RC tyres—powerful enough for competitive use, durable enough for everyday bashing on UK streets and tracks. The integrated closed-cell foam insert provides sophisticated dampening without excessive material that could cause vague, unresponsive handling. When paired with the Pro-Spec Aluminium front wheel (compatible with models PRO284700T1, PRO284700T2, and PRO284700T3), this assembly delivers a 5.6-inch (142mm) package height and creates a complete rolling solution optimised for asphalt and smooth hard-pack surfaces. The semi-slick tread pattern with cornering sipes excels on tarmac, concrete, driveways, and parking lots—environments where traditional knobby off-road tyres would perform poorly. This tyre's superior performance on smooth surfaces combined with the forgiving S3 compound makes it an excellent choice for riders transitioning from factory setups to performance aftermarket equipment, and an essential component for serious Promoto-SM competitors seeking marginal gains through superior tyre technology.

Frequently Asked Questions
- Is the Pro-Line Supermoto S3 tyre suitable for beginners? — Absolutely. The soft S3 compound is forgiving and responsive, making it ideal for riders developing their skills. The semi-slick design provides more feedback than factory tyres, helping you learn proper throttle control and cornering technique. Many RC enthusiasts in the UK consider this an essential upgrade when transitioning from basic factory rubber to performance equipment.
- What surfaces perform best with the Supermoto S3 front tyre? — These tyres are optimised for asphalt and smooth hard-packed surfaces. They deliver superior grip on tarmac, concrete, smooth car parks, and even polished driveways. Whilst you can use them on slightly rougher surfaces, performance drops significantly on loose gravel or muddy terrain—for those conditions, traditional knobby off-road tyres are more appropriate.
- Can I use the Supermoto S3 front tyre on my existing wheels? — No. This tyre is specifically designed for Pro-Line Pro-Spec Aluminium wheels (models PRO284700T1, PRO284700T2, and PRO284700T3). It cannot be fitted to standard plastic wheels or other aluminium wheel designs. If you don't already own compatible Pro-Spec wheels, you'll need to purchase them separately.
- How long do these tyres last compared to factory rubber? — The thicker carcass and premium S3 compound significantly extend tyre life compared to standard factory Promoto-SM tyres. Actual lifespan depends on riding intensity, surface type, and maintenance, but most users report 3-5 times longer service life. The investment in these premium tyres pays dividends through reduced replacement costs over time.
- Is this a single tyre or a pair? — This package contains one front tyre assembly. For a complete wheel upgrade, you'll need to purchase two of these front tyres (one for each side of your motorcycle). To fully outfit your Promoto-SM, also consider pairing this with the Supermoto Rear tyre mounted on Pro-Spec Wheel Sleeve (model PRO1024511) for matching front and rear performance.
- What's the difference between S3 compound and other Pro-Line compounds? — Pro-Line offers various compounds graded from S1 (hard) through S4 (very soft). The S3 soft compound used in this Supermoto tyre is mid-range, offering excellent grip without excessive wear. It's ideal for mixed conditions and general riding, whilst harder compounds last longer on rough surfaces and softer compounds (S4) provide maximum grip for racing-only applications.
- Can I use these tyres in wet conditions? — Whilst the semi-slick design provides some wet grip, these tyres are optimised for dry asphalt. Wet performance is reduced compared to treaded patterns. For regular wet-weather riding, consider traditional knobby tyres that channel water more effectively.
- Do these tyres need special maintenance? — Treat them like any quality RC tyre: store in a cool, dry location away from direct sunlight to prevent compound degradation. Clean after use to remove dirt and debris. Check the plastic sleeve mounting regularly for wear. When performance drops noticeably, the tyres have worn down and require replacement—the closed-cell foam inserts won't wear out but should be replaced with the tyres for optimal performance.
