Built specifically for rock crawling applications, these Class 1 tyres provide an authentic scaled appearance with their 4.19 inch outer diameter, whilst the aggressive tread pattern is engineered to tackle the toughest obstacles. The super-soft C3 compound rubber bites into loose and muddy surfaces with exceptional gripping power, making them ideal for crawling over slippery rocks, muddy banks and challenging terrain that would defeat lesser tyres. If you are searching for rock crawler tyres UK or seeking pre-mounted 1.9 inch wheels for your RC crawler, the Ascend CR C3 represents outstanding value and performance.
These tyres arrive factory-mounted to durable black composite plastic wheels featuring 12mm hex connections, making them compatible with the vast majority of 1/10 scale rock crawlers and off-road RC vehicles. The package includes two complete tyre and wheel assemblies, providing front and rear coverage for your vehicle. Foam inserts are included to support the tyre sidewalls and maintain structural integrity during intense climbing and rock crawling manoeuvres.
Key Features
- Class 1 Size (4.19 inch Outer Diameter) — The Class 1 specification ensures maximum scale appearance that matches the proportions of full-size vehicles, giving your RC crawler an authentic, purposeful look that enthusiasts appreciate. This larger apparent tyre size is specifically designed for rock crawling where scale detail matters.
- Super-Soft C3 Compound Rubber — The C3 compound is engineered to be exceptionally soft, providing maximum grip and conformability to uneven surfaces. This softer compound allows the tyre to deform and grip irregular rock surfaces, muddy terrain and loose ground far more effectively than harder compounds, which is essential for serious rock crawling performance.
- Aggressive Tread Pattern — The tyre features a purposefully aggressive tread design that actively bites into loose and muddy surfaces. This tread pattern is not aesthetic—it is functionally engineered to enhance grip on the types of challenging surfaces that rock crawlers encounter, from slippery rocks to muddy climbs and treacherous obstacles.
- Pre-Mounted on Black Composite Wheels — These tyres arrive already mounted on durable black composite plastic wheels, eliminating assembly time and reducing the risk of installation errors. The black composite material provides strength whilst remaining lightweight, and the wheels are finished in an attractive black colour that complements most RC crawler colour schemes.
- 12mm Hex Fitting — The standard 12mm hex connection is universal across 1/10 scale RC vehicles, ensuring compatibility with the vast majority of rock crawlers, buggies and off-road RC cars available in the UK market. This standardised fitting means simple, tool-free installation on most vehicles.
- Foam Inserts Included — The included foam inserts support the tyre sidewalls and maintain structural integrity during aggressive manoeuvres. These inserts prevent tyre collapse when climbing vertical obstacles and absorb impacts, protecting both tyre and wheel from damage and extending the lifespan of your investment.
- Suitable for Front and Rear Use — These versatile tyres are equally at home on the front or rear of your RC crawler, providing consistent grip and performance regardless of position. This versatility means you can purchase multiple pairs with confidence that they will perform equally well across your vehicle.
- Factory-Mounted and Ready to Install — There is no need for tyre mounting tools, bead-seating procedures or wheel balancing—simply open the package and install these pre-mounted assemblies onto your vehicle. This ready-to-run approach is perfect for RC enthusiasts who want to spend more time driving and less time in the workshop.
Technical Performance
The DURATRAX Ascend CR C3 tyres represent careful engineering optimised for the specific demands of rock crawling. The 1.9 inch inner diameter wheel combined with the 4.19 inch outer tyre diameter creates a tall, narrow profile that mimics full-size off-road tyres whilst maintaining the scale appearance critical to realistic rock crawling setups. The super-soft C3 rubber compound is deliberately chosen for this application—harder compounds would bounce and skip across obstacles, whilst the C3 compound conforms to irregular surfaces and maintains contact, translating to superior grip. The aggressive tread pattern is not random; each element is positioned to maximise surface contact and create mechanical grip through texture rather than relying solely on rubber grip. The black composite plastic wheels are injection-moulded for consistency and durability, able to withstand the repetitive impacts and stresses of rock crawling without cracking or deforming. The 12mm hex standard ensures zero compatibility issues with modern RC vehicles. Foam inserts provide progressive damping as the tyre compresses under load, absorbing shock and protecting both tyre and wheel from the sudden impacts that come from dropping over rocks or landing from elevation changes. This combination of materials, compounds and engineering makes these tyres a serious choice for UK RC enthusiasts who demand performance and reliability from their rock crawling setups.

Frequently Asked Questions
- Are these tyres suitable for rock crawling and obstacle courses? — Yes, absolutely. These tyres are specifically engineered for rock crawling applications. The super-soft C3 compound and aggressive tread pattern provide exceptional grip on rocks, mud and challenging terrain. The Class 1 size and scale appearance make them ideal for serious crawling setups.
- What vehicles are these tyres compatible with? — These tyres feature standard 12mm hex fittings, making them compatible with the vast majority of 1/10 scale RC vehicles including rock crawlers, buggies, trucks and off-road cars. If your vehicle uses 12mm hex connections, these will fit. Check your vehicle manual if you are unsure.
- Are these pre-mounted tyres ready to use straight from the box? — Yes, these tyres arrive factory-mounted on wheels and ready to install directly onto your RC vehicle. There is no mounting, balancing or preparation required—simply fit them to your vehicle using standard hex adapters and you are ready to drive.
- What is the difference between the C3 compound and other compounds? — The C3 is a super-soft compound specifically designed for grip and conformability. Softer compounds grip better on irregular surfaces and loose terrain, which is critical for rock crawling where the tyre needs to conform to rock surfaces and uneven ground. Harder compounds are faster but sacrifice grip on obstacles.
- Can I use these on the front and rear of my vehicle? — Yes, these versatile tyres are suitable for both front and rear positions. You can use them anywhere on your vehicle and they will deliver consistent performance and grip.
- Are foam inserts necessary? — Yes, the foam inserts included with these tyres serve an important function. They support the tyre sidewall, prevent tyre collapse during aggressive climbing, absorb impacts and help protect the wheel and tyre from damage. They should be left in place for optimal performance and durability.
- What makes these Class 1 tyres different from other sizes? — Class 1 tyres have a 4.19 inch outer diameter, making them larger and providing greater scale appearance compared to smaller tyre sizes. The larger contact patch and additional sidewall provide better grip and obstacle conformability, which is why serious rock crawlers prefer Class 1 sizes.
