Overview
Introducing Pro-Line's next level performance in carpet racing tyres, the PRO 1/10 Prism CR3 Rear 2.2 inch/3.0 inch Carpet Short Course Tires deliver championship-winning grip and consistency for 1/10 short course trucks. With the exploding popularity of 1/10 carpet off-road racing over the last few years, Pro-Line set out to raise the bar on carpet tyres with their CR3 (Medium) and CR4 (Soft) compounds, specifically engineered to suit today's high-grip carpet tracks. These rear tyres are destined to change the carpet racing scene and help you achieve faster, more consistent lap times on your RC short course truck. Whether you're a seasoned competitor looking to shave milliseconds off your times or a dedicated racer stepping up to carpet track competition, these professional-grade tyres represent the cutting edge of RC car tyre technology available in the UK.
Pro-Line's factory team of drivers has extensively tested the CR3 compound across many different styles of carpet surfaces, and the results speak for themselves. The CR4 compound has already taken its first victory at the 2021 US Carpet Off-Road Championship in Cleveland in the hands of Aydin Horne, with Ryan Cavalieri making it a 1-2, demonstrating the performance credentials of Pro-Line's latest carpet tyre range. These Prism SC rear tyres bring the popular, proven Prism tread pattern to the short course class, featuring 1,280 ultra-sharp prism-shaped pins that grip the carpet with the tenacity of Velcro. The pins are laid out in a unique pattern that delivers superior grip compared to traditional pin point tyres, whilst the smaller pin design means faster lap times without sacrificing consistency or durability.
Made in the USA since 1982, Pro-Line brings decades of expertise and quality craftsmanship to every tyre they produce. These rear tyres are ideal for racers using Pro-Line's short course wheels in the 2.2 inch outer with 3.0 inch inner dual profile configuration. To maximise performance, Pro-Line recommends pairing these Prism SC rear tyres with Pro-Line's Prism SC front tyres for optimum performance across your entire tyre setup.
Key Features
- 1,280 Ultra-Sharp Prism-Shaped Pins — This massive pin count creates an aggressive, multi-directional grip pattern that adheres to carpet surfaces with exceptional tenacity, similar to high-grip Velcro tape. The sheer number of contact points means your short course truck maintains grip through corners and acceleration zones that would cause traditional tyres to slip or slide, directly translating to faster lap times and better consistency run after run.
- Smaller Pin Design for Faster Lap Times — Unlike larger, conventional pin-point tyres, the Prism features smaller individual pins arranged in a denser pattern. Smaller pins mean less rolling resistance and reduced deformation during cornering, allowing your RC truck to maintain higher speeds through technical sections of the track whilst maintaining precise handling characteristics.
- CR3 Medium Compound — Specifically formulated for high-grip carpet track conditions, the CR3 medium compound offers the ideal balance between grip and longevity. This compound has been tested by Pro-Line's factory team of drivers and proven to deliver improved grip and consistency across many different styles of carpet surfaces, whether you're running on dense indoor carpet or smoother synthetic surfaces.
- Knife-Edge Pin Orientation — The prism pins are positioned with the knife edge pointed both front-to-back and side-to-side, maximising the cutting effect into the carpet fibres for maximum initial grip. This dual-direction orientation ensures that the pins stay sharp and effective even as the tyres wear down through multiple heats and qualifying rounds, maintaining consistent performance throughout the day.
- Long-Lasting and Super Consistent Performance — The combination of the robust CR3 compound and the strategically positioned ultra-sharp pins delivers extended tyre life without the performance degradation common in softer compounds. You'll experience consistent lap times throughout the day, round after round, without the tyre falling off a cliff as it wears, which is critical during competitive carpet racing events.
- Purpose-Built for 1/10 Short Course Trucks — These rear tyres are engineered specifically for the short course truck class, with the 2.2 inch outer diameter and 3.0 inch inner diameter dual profile fitting standard short course wheels. This class-specific design ensures perfect fitment and optimal performance characteristics for your SC truck platform.
- Made in the USA Since 1982 — Pro-Line's commitment to quality and American manufacturing excellence is evident in every aspect of these tyres. With over four decades of experience in RC tyre development, Pro-Line brings proven expertise and rigorous quality control to every product, ensuring you receive tyres that meet the demanding standards of competitive racers and professional drivers.
Technical Performance
The PRO 1/10 Prism CR3 Rear 2.2 inch/3.0 inch Carpet Short Course Tires represent the pinnacle of carpet racing tyre engineering and performance. The dual profile wheel compatibility—2.2 inch outer diameter with 3.0 inch inner diameter—ensures these tyres fit standard short course racing wheels and platforms perfectly. The CR3 medium carpet compound has been meticulously formulated and extensively field-tested by Pro-Line's factory team to deliver the optimal balance between raw grip, consistency, and longevity on high-grip carpet surfaces. The engineering breakthrough lies in the 1,280 ultra-sharp prism-shaped pins, which are significantly smaller than traditional pin-point designs but far more numerous, creating an unprecedented number of grip points per square inch of tyre surface. Each pin features a knife-edge geometry oriented for maximum cutting action into the carpet fibres in both longitudinal and lateral directions, ensuring grip is maintained through corners, acceleration zones, and braking areas. This multi-directional cutting action is what sets the Prism apart from competitors—the pins don't just sit on top of the carpet, they bite into it, providing the kind of raw grip necessary for shaving hundredths of a second off lap times in competitive 1/10 short course racing. The tyre construction maintains sharp pin definition throughout the wearing process, meaning your performance doesn't degrade as significantly as it would with traditional softer compounds that round off and flatten with use. For UK RC racers competing in indoor carpet championships and regional events, these tyres deliver the performance consistency and grip levels expected at the top levels of competitive short course racing.

Frequently Asked Questions
- What is the CR3 compound and why does it matter for carpet racing? — The CR3 is Pro-Line's medium compound specifically engineered for high-grip carpet track surfaces. Unlike generic tyres that must compromise across multiple surface types, the CR3 is formulated exclusively for carpet racing conditions, delivering superior grip and consistency on the dense, textured surfaces found in indoor carpet racing facilities across the UK. The compound has been tested by Pro-Line's factory racing team and proven at championship level with victories at the 2021 US Carpet Off-Road Championship.
- How many pins does the Prism have and why does that matter? — The Prism features 1,280 ultra-sharp prism-shaped pins laid out in a unique high-density pattern. This massive pin count creates far more contact points with the carpet surface compared to traditional pin-point tyres, delivering superior grip whilst the smaller individual pins actually reduce rolling resistance, resulting in faster lap times. More pins mean more consistent grip throughout the wear life of the tyre, which is essential for maintaining competitive pace throughout multiple qualifying heats.
- Will these tyres fit my short course truck? — These rear tyres are designed specifically for 1/10 short course trucks using standard short course wheels with a 2.2 inch outer diameter and 3.0 inch inner diameter dual profile configuration. Check your wheel specifications to confirm compatibility before ordering. If you're unsure about fitment, our expert RC team at RC Model Shop can advise you on the correct tyre size for your particular SC truck platform.
- Should I pair these with front Prism tyres for best performance? — Yes, Pro-Line specifically recommends pairing the Prism SC rear tyres with Pro-Line's Prism SC front tyres for optimum performance. Having a matched set of front and rear Prism tyres ensures consistent handling characteristics, predictable balance, and repeatable lap times throughout your racing day. Mixing different tyre patterns or compounds can create unpredictable handling traits that make it harder to dial in your truck's setup.
- How do these compare to other carpet racing tyres available in the UK? — The Prism CR3 tyres stand out due to the combination of 1,280 ultra-sharp pins in a unique high-density pattern, the medium CR3 compound specifically formulated for carpet, and the knife-edge pin orientation that maintains grip through the tyre's lifespan. Unlike universal tyres designed to work on multiple surfaces, the Prism CR3 is purpose-built for carpet racing, which is why Pro-Line's factory drivers have achieved championship-level results with this tyre range. The proven track record at elite racing events demonstrates the performance advantage these tyres deliver.
- How long do these tyres last during competitive racing? — The CR3 compound and robust construction deliver extended tyre life compared to softer compounds, and more importantly, the performance remains consistent throughout the wearing process. You won't experience the dramatic performance cliff that occurs with tyres that degrade rapidly. Most racers find these tyres last through multiple qualifying rounds and final heats in typical racing events, though exact wear rates depend on your driving style, track conditions, and truck setup.
- Are these suitable for casual bashing or only for competitive racing? — These tyres are specifically engineered for competitive carpet racing environments and will deliver their maximum benefit on high-grip indoor carpet surfaces. Casual bashers on outdoor surfaces or mixed terrain will not experience the same performance advantages, and the premium pricing reflects their focus on championship-level performance rather than general-purpose recreational use.
