Whether you are competing in a local RC club event or practising at home, these tyres deliver the professional-grade performance that separates winners from the rest. RC car UK enthusiasts know that tyre selection is absolutely critical to success, and RC4WD has invested significant engineering into these Bully Competition tyres to give you a genuine competitive advantage.

What makes these tyres stand out in the crowded RC tyre market is RC4WD's Advanced X2S³ compound technology. This is not a generic rubber mixture — it is a scientifically developed formula that has been refined through countless hours of real-world testing. The compound strikes an exquisite balance between grip and durability, ensuring that you maintain consistent traction lap after lap without excessive wear. For competitors and serious hobbyists running ready to run RC vehicles or custom crawler builds, consistency across multiple heats is essential, and these tyres deliver exactly that. The 1.9-inch wheel fitment is the industry standard for modern precision crawling, making these tyres compatible with a wide range of current RC crawler platforms and wheel designs from RC4WD itself.

Each pair comes supplied with two-stage foam inserts, which are absolutely essential for maintaining proper tyre structure and preventing deformation during high-pressure competition runs. This attention to detail, combined with competitive pricing and genuine RC4WD quality assurance, makes these tyres an intelligent choice for anyone serious about their RC crawling performance. Available now through RC Model Shop, your trusted authorised UK RC retailer, these tyres are ready to ship and ready to improve your competition results.

Key Features

• Advanced X2S³ Compound Technology — RC4WD's proprietary rubber compound is engineered to deliver superior grip characteristics whilst maintaining exceptional durability throughout extended competition sessions. This specialized formula responds consistently across varying terrain and conditions, which is absolutely critical when you are competing against other pilots where every fraction of second counts.
• Precision Competition Profile — Sized at 4.21 inches (107mm) outer diameter and 1.25 inches (32mm) width, these tyres offer a compact, focused footprint specifically optimised for competition crawling. This geometry has been tested extensively to provide optimal ground contact and predictable handling characteristics that experienced pilots demand.
• Included Two-Stage Foam Inserts — Each pair of tyres comes complete with two-stage foam inserts that provide essential structural support to the tyre carcass. These inserts prevent the tyre from collapsing under load and maintain consistent sidewall stiffness, ensuring repeatable performance run after run. This is a critical feature that many competitor tyres force you to purchase separately.
• Lightweight Construction — Weighing just 1.51 ounces (43.0 grams) per tyre, these are engineered for minimal unsprung weight, which directly improves vehicle handling, suspension response and overall agility during precise crawling manoeuvres. Less rotating weight means faster directional changes and more responsive control.
• 1.9-Inch Wheel Compatibility — These tyres are specifically designed to fit 1.9-inch wheels, which is the current industry standard for serious RC crawlers and competition vehicles. RC4WD tyres and wheels are engineered to work harmoniously together, offering optimal fitment and consistent performance characteristics.
• Designed for Serious Competitors — Every aspect of these tyres, from the compound selection to the dimensional specifications, has been optimised for the dedicated competitor who takes their RC crawling seriously. These are not beginner-level tyres; they are professional-grade components for pilots who understand that equipment quality directly influences results.

Technical Performance

The RC4WD Bully Competition 1.9'' Scale Tyres represent a significant engineering achievement in the precision crawling tyre category. The Advanced X2S³ compound has been developed through extensive real-world testing to provide consistent grip across a variety of terrain conditions whilst maintaining structural integrity through multiple competitive heats. The 107mm outer diameter and 32mm width create an optimal footprint that balances ground contact area with manoeuvrability — critical factors in competition crawling where precision and control are paramount. The inclusion of two-stage foam inserts is essential engineering; the dual-stage design provides both structural support and some degree of compliance, allowing the tyre to conform to irregular terrain whilst maintaining consistent sidewall support. With each tyre weighing approximately 43 grams, the overall mass is kept to a minimum, which reduces unsprung weight and significantly improves the vehicle's ability to respond quickly to control inputs. The inner diameter of 46.0mm ensures compatibility with standard 1.9-inch wheel designs. These tyres are purpose-built for RC crawler UK competition enthusiasts who demand reliability, consistency and measurable performance advantages from their equipment. The tread depth specification (TBC) will be confirmed by RC4WD as this product moves through quality assurance, ensuring that the final production tyres meet exacting standards for grip and durability across competitive terrain.

Frequently Asked Questions

• Are RC4WD Bully Competition tyres suitable for beginners or do I need to be a competition pilot? — Whilst these tyres are specifically engineered for competitive crawling and will certainly benefit beginners by providing consistent, predictable grip, they are optimised for pilots who take their RC crawling seriously. If you are just starting out with RC crawling as a hobby and are not competing, you might find these tyres offer more precision than you require. However, if you aspire to competition or want the best possible performance from your crawler setup, these tyres will deliver immediate and noticeable benefits. The choice ultimately depends on your ambitions within the hobby and how seriously you intend to pursue RC crawling.
• What wheels do these RC4WD Bully Competition tyres fit? — These tyres are designed to fit 1.9-inch wheels, which is the current industry standard for serious RC crawlers and competition vehicles. RC4WD tyres and wheels are engineered to work optimally together, and the fitment with RC4WD's own 1.9-inch wheel range is guaranteed. However, due to the many different design approaches used by other manufacturers in the RC industry, fitment with non-RC4WD brand wheels cannot be guaranteed. We always recommend confirming compatibility with your specific wheel model before purchasing, or contacting our knowledgeable team at RC Model Shop who can advise on cross-brand compatibility for your particular setup.
• What does the Advanced X2S³ compound mean and why does it matter? — The Advanced X2S³ compound is RC4WD's proprietary rubber formula that has been scientifically developed and extensively tested to deliver optimal grip and durability for competition crawling. This is not a generic tyre compound; it is specifically engineered to maintain consistent traction across varied terrain and conditions, which is essential for competitive success. The compound resists excessive wear during extended sessions whilst providing the grip characteristics that serious crawlers demand. By investing in a proper competition-grade compound, RC4WD ensures that you get repeatable, predictable performance rather than gradual degradation through your competition heats.
• Why are the foam inserts so important and are they essential? — Yes, the included two-stage foam inserts are absolutely essential components. They provide structural support to the tyre carcass, preventing the tyre from collapsing under load and maintaining consistent sidewall stiffness throughout your crawling sessions. This structural consistency is critical for maintaining predictable handling and ensuring that your tyres perform the same way in your first run as they do in your final heat. Many RC tyre manufacturers sell foam inserts separately, forcing customers to purchase them at additional cost; RC4WD includes them as standard, recognising their importance to proper tyre performance.
• How much do these tyres weigh and why does that matter? — Each RC4WD Bully Competition tyre weighs approximately 1.51 ounces (43.0 grams), making them relatively lightweight for a competition-grade crawler tyre. This lightweight construction directly benefits your vehicle by reducing unsprung mass, which improves suspension response, enhances manoeuvrability and allows your crawler to react more quickly to terrain changes and control inputs. In competition crawling, every fraction of a gram contributes to overall performance, and lighter tyres mean a lighter, more responsive vehicle.
• What is the difference between these competition tyres and recreational crawler tyres? — Competition-focused tyres like the Bully Competition range are engineered with several critical differences from recreational options. The Advanced X2S³ compound is specifically developed for consistent grip across multiple heat cycles, whereas recreational tyres may prioritise durability over consistency. The geometric specifications (diameter and width) are optimised for predictable handling and control during precision manoeuuvres, and the included two-stage foam inserts represent an understanding of how serious competitors need their tyres to perform. Additionally, competition tyres are produced with tighter quality control to ensure consistency between individual units, whereas recreational tyres may have more variation between samples. If you are competing or aspire to compete in RC crawling, investing in purpose-built competition tyres like these will deliver measurable performance advantages.
