Key Features
- Class 1 Legal Trencher Tread Design — These tyres feature a highly aggressive tread pattern that meets Class 1 competition standards, allowing you to compete in sanctioned RC crawler events whilst maintaining that authentic rock terrain look that complements scale rigs.
- Extremely Aggressive Tread Pattern with Multiple Sipes and Levels — Each tread block contains multiple sipes (thin cuts in the rubber) and operates at multiple depth levels, creating incredible tread flex that adapts to every rock contour and surface variation your RC crawler encounters.
- Highly Detailed Connected Side Tread for Optimum Side-Hilling Performance — The connected tread pattern extends across the sidewall of each tyre, providing the next level of side-hilling performance and grip when your RC crawler is at extreme angles, which only slides out when you want it to for controlled, predictable handling.
- Inspired by Pro-Line's Popular All-Terrain Trencher Design — Pro-Line took their insanely popular all-terrain Trencher tread pattern and adapted it specifically for Class 1 rock crawling, meaning you get proven tread technology refined for serious off-road performance.
- Super Soft Predator Compound — The Predator compound offers a super-soft rubber formulation that maximises traction across varied rock surfaces, wet conditions, and challenging terrain where grip is absolutely critical for RC crawler success.
- Suitable for Scale Rigs and Competition Use — With their detailed, realistic appearance and genuine performance credentials, these tyres look fantastic on scale rigs whilst delivering legitimate competitive advantages, proving that style and substance can go hand-in-hand in RC crawling.
- Versatile Front or Rear Fitment — These tyres work equally well on the front or rear axles of your 1/10 scale RC crawler, giving you flexibility in tyre management and allowing you to rotate tyres for even wear across your RC car.
- American-Made Quality Since 1982 — Pro-Line has manufactured premium RC tyres in the USA for over four decades, with a proven track record of durability, performance consistency, and innovation that serious RC enthusiasts trust.
Technical Performance
The Pro-Line Class 1 Trencher Predator tyres deliver exceptional technical performance through their meticulously engineered construction and material science. At 4.19 inches in outer diameter and 1.49 inches in width, these 1.9" wheel-diameter tyres provide the optimal size-to-performance ratio for 1/10 scale RC rock crawlers, offering a substantial contact patch without compromising manoeuvrability. The Predator compound rubber, classified as super-soft, is specifically formulated to bite into rock surfaces and maintain grip across temperature ranges typical of UK outdoor conditions. The open-cell foam inserts included with the tyre pair absorb impacts and provide structural support whilst allowing the tyre sidewalls to flex naturally—a critical feature for maintaining traction when your RC crawler is climbing steep inclines or traversing extremely uneven terrain. The tread design incorporates multiple depth levels and sipe configurations that work together as a system: as the tyre flexes under load, different tread blocks engage and disengage with the rock surface, continuously adapting grip levels throughout your RC crawler's movement. This dynamic traction system means the Trencher tyres perform effectively across boulder fields, shale, wet rocks, and technical obstacle courses, making them genuinely versatile for the diverse terrain conditions encountered across the UK and Europe. The manufacturing process and quality control standards that have defined Pro-Line's 40+ year reputation are evident in the consistent quality and performance you'll experience session after session.

Frequently Asked Questions
- What makes the Trencher tyre different from other Class 1 rock crawling tyres? — The Trencher combines Pro-Line's proven all-terrain tread design with Class 1-specific engineering, featuring multiple sipe levels in each tread block and highly detailed connected side tread for superior side-hilling performance. The combination of extreme tread aggressiveness with genuine scale appearance makes the Trencher unique among Class 1 options available to UK RC enthusiasts.
- Will these tyres fit my RC crawler? — These tyres are designed for standard 1.9" rock crawling wheels and work on any 1/10 scale RC crawler that accepts 1.9" tyres in the front or rear position. If your RC car currently uses 1.9" wheels, the Trencher tyres will fit directly—the included foam inserts handle mounting and support.
- What is the Predator compound, and how does it differ from the G8 compound option? — The Predator compound is a super-soft rubber formulation that prioritises maximum traction and grip across varied rock surfaces, wet conditions, and challenging terrain. Pro-Line also offers these Trencher tyres in their legendary G8 compound, which is firmer and better suited to smoother surfaces or warmer conditions. For UK rock crawlers who frequently encounter moisture and algae-covered rocks, the Predator compound's extra grip often proves invaluable.
- Are these tyres suitable for beginners to RC rock crawling? — Absolutely. The Trencher tyres are Class 1 legal competition-grade products, but their design makes them accessible and effective for any RC crawler operator. Beginners will appreciate the reliable grip and predictable handling, whilst experienced competitors will exploit the advanced tread technology for competitive advantage. There's no learning curve—they simply perform from the moment you mount them.
- How often will I need to replace these tyres? — Tyre lifespan depends heavily on usage intensity, terrain type, and maintenance. Rock crawling creates less tyre wear than high-speed bashing, so quality Class 1 tyres typically last many months of regular use. When tread depth diminishes or you notice reduced grip, replacement is recommended. The foam inserts can also be replaced separately if compressed over time.
- Do these tyres come with wheel rims included? — No, these are tyres and foam inserts only. You'll need to mount them on your existing 1.9" RC crawler wheels. The foam inserts are included to provide mounting support and impact absorption, but wheels must be purchased separately if you don't already have them.
- Can I use these tyres on both front and rear axles? — Yes, the Trencher design works equally well in front or rear positions, and the included pair allows you to fit both front and rear axles with identical tyres, or rotate tyres between sessions for even wear and consistent performance.
