Z-T0087

Overview

The RC4WD Rock Crusher X/T 2.2" Tyres (Z-T0087) represent a premium tyre option designed specifically for demanding off-road RC applications. These are purpose-built tyres for serious RC enthusiasts in the UK who demand maximum grip, durability and scale realism in their crawler and trail builds. Whether you're tackling rocky terrain, muddy trails or challenging obstacle courses, the Rock Crusher X/T delivers the performance and aesthetics that dedicated RC 4x4 builders have come to expect from RC4WD's advanced tyre technology.

Supplied as a pair with foam inserts included, the Rock Crusher X/T 2.2" tyres are engineered for 2.2" wheels and are particularly well-suited to scale trail and crawler builds using 1/10 scale platforms such as the Axial Yeti. The extremely deep tread pattern isn't just for show—it provides genuine off-road traction across multiple terrain types whilst maintaining that authentic, aggressive appearance that modern RC scale crawlers demand. For a complete truck build, you'll need two sets of these tyres, making them an essential upgrade for serious RC bashers and competition crawlers across the UK.

RC car enthusiasts and RC crawler builders will appreciate the engineering quality that goes into every RC4WD product. These tyres have been designed with the understanding that real off-road performance requires more than just rubber—it requires advanced compound technology, structural integrity, and a proven tread design that has been tested in the field by experienced RC builders and competitors.

Key Features

• Advanced X3 Soft Compound — RC4WD's proprietary soft rubber compound delivers enhanced grip across varied terrain types, ensuring your RC crawler maintains traction on both rocky surfaces and muddy trails. The softer compound is especially beneficial in cooler UK weather conditions where standard compounds can become too hard and lose their grip properties.
• Super-Strong Sidewalls — The reinforced sidewall construction prevents tyre deformation during aggressive cornering and high-load situations, maintaining structural integrity even when climbing steep obstacles or navigating technical terrain. This strength is critical for scale crawlers and rock buggies that encounter extreme driving conditions and side loads during competition events.
• Extremely Deep Tread Pattern — The aggressive, deep tread design maximises mud evacuation and provides multiple edge points for grip, whilst simultaneously enhancing the authentic, realistic appearance that scale crawlers are designed to achieve. The deep treads work effectively across loose surfaces, packed earth, and rocky terrain common in UK trail centres and competition courses.
• Foam Inserts Included — Each pair comes with two foam inserts specifically designed for these tyres. Foams are essential for maintaining tyre shape during storage and transport, and they provide structural support during high-speed runs, preventing tyre rollover and maintaining consistent handling characteristics throughout your RC session.
• 2.2 Inch Wheel Compatibility — Designed specifically for 2.2" wheels, these tyres offer broad compatibility with popular 1/10 scale crawler and trail platforms. The standardised 2.2" mounting diameter makes it easy to upgrade existing builds without requiring new wheels or suspension modifications.

Technical Performance

The Rock Crusher X/T 2.2" tyres represent a significant advancement in RC crawler tyre technology, combining materials science with practical off-road design. At 5.5 inches (139mm) outer diameter and 1.97 inches (50mm) width, these tyres provide an ideal proportional footprint for 1/10 scale platforms, delivering realistic scale proportions whilst maintaining adequate ground clearance for technical terrain. Each tyre weighs 5.33 ounces (151 grams), giving a total unsprung mass of 302 grams per pair—a weight that experienced RC builders recognise as optimal for maintaining suspension geometry and reducing unsprung mass that could compromise handling. The tread depth is designed to be substantial enough for genuine off-road performance without becoming too soft or prone to degradation through repeated use on abrasive rock surfaces. RC4WD's advanced X3 soft compound has been engineered through extensive testing to maintain consistent grip temperatures across the range of ambient conditions experienced throughout the UK, from summer heat to winter cold. The sidewall construction utilises reinforced rubber that resists puncture and tearing whilst remaining flexible enough to absorb impacts from technical terrain and maintain tyre contact during articulation movements. This combination of material science and proven tread design makes the Rock Crusher X/T an excellent choice for competitive crawlers, casual bashers, and dedicated scale trail builders alike.

Frequently Asked Questions

• Are these tyres suitable for beginners building their first RC crawler? — Yes, absolutely. The Rock Crusher X/T tyres are an excellent choice for newcomers to the RC crawler hobby. They come with foams included, meaning there's nothing else to purchase separately, and their straightforward 2.2" compatibility works with many popular beginner-friendly platforms. The soft compound and aggressive tread make them forgiving on various terrains, helping new builders develop their skills without worrying about tyre performance limitations.
• What makes the X3 soft compound better than standard tyre rubber? — RC4WD's proprietary X3 soft compound is specifically formulated to maintain consistent grip across different temperatures and surface types. In the UK's variable climate, this means the tyres perform reliably whether you're running in summer heat or winter cold, and whether you're on dry rock, wet mud, or loose terrain. The softness provides enhanced bite on obstacles whilst still maintaining durability through extended use.
• Do I need to purchase anything else to use these tyres? — The tyres come complete with foam inserts, so you don't need to buy foams separately. You will need 2.2" wheels to mount them on, and obviously a complete RC crawler platform to install them in. If you're building a complete truck, you'll need two sets of these tyres (eight tyres total) rather than just one pair.
• How do these compare to other RC4WD tyre options? — RC4WD produces multiple tyre models for different applications. The Rock Crusher X/T offers the deepest, most aggressive tread pattern of their lineup, making it ideal for challenging terrain and rock crawling. If you compare it to models like the MudSlinger or Rock Stomper, the Rock Crusher X/T delivers more extreme tread depth and is optimised specifically for technical off-road performance. The X3 soft compound is consistent across their range but the tread design makes the Rock Crusher X/T the most capable option for serious crawling.
• Will these fit my existing 2.2" wheels? — These tyres are designed for standard 2.2" wheels. RC4WD recommends using them with RC4WD wheels for guaranteed fitment and performance, as the company controls both the tyre and wheel design together. Compatibility with third-party wheels cannot be guaranteed due to design differences between manufacturers, though in many cases they will work acceptably.
• What's the difference between the Z-T0087 and the older RCrusher2.2 part number? — These are the same product. RC4WD updated their part numbering system, and the Rock Crusher X/T 2.2" tyres are now designated Z-T0087 instead of RCrusher2.2. The tyre specifications and quality remain identical; this is purely a catalogue designation change.
• Are these tyres durable for frequent use? — Yes, the Rock Crusher X/T tyres are engineered for demanding off-road use and competitive applications. The super-strong sidewalls resist damage during technical climbing and articulation, and the advanced compound maintains its properties through extended use. Like all RC tyres, they will gradually wear with frequent use on abrasive surfaces like rock, but the deep tread design means you have substantial material to work with before replacement becomes necessary.
