Overview
Experience the future of Class 1 rock crawling performance with the Pro-Line 1/10 Class 1 Hyrax G8 Front/Rear 1.9" Rock Crawling Tires. Designed from the ground up for maximum grip on the toughest terrain, these Class 1 legal tires are the perfect choice for serious RC rock crawlers across the UK who demand uncompromising performance on challenging landscapes. Whether you're tackling rocky mountains, slick surfaces, or technical terrain, the Hyrax represents a revolutionary advancement in scale crawling tyre technology that will transform your RC climbing experience.
Pro-Line has engineered these 1.9" tyres specifically for rock crawling enthusiasts who refuse to compromise on performance or scale authenticity. The Hyrax builds on decades of Pro-Line's legendary reputation—the company has claimed 12 IFMAR World Championships and hundreds of U.S. National and European Championships since 1982. These tyres are made in the USA using Pro-Line's time-proven G8 compound, delivering reliability and performance you can depend on, whether you're a competitive racer, weekend basher, or dedicated scale crawler exploring new RC terrain.
The Hyrax G8 represents a significant leap forward in tyre design philosophy. Rather than simply upgrading existing patterns, Pro-Line designed the Hyrax completely from scratch to maximize grip on the toughest rock crawling conditions. From the aggressive tread pattern to the innovative sidewall design, every element has been carefully engineered to give your 1/10 scale crawler the mechanical grip it needs to conquer obstacles that would stop lesser tyres in their tracks.
Key Features
- Class 1 Legal Design — These tyres meet all Class 1 competition regulations, making them perfect for organised RC events, competitions, and sanctioned rock crawling challenges across the UK and beyond. You can use them with complete confidence in any Class 1 event without worrying about rule violations.
- Ground-Up Design Philosophy — Rather than modifying existing tyre patterns, Pro-Line engineered the Hyrax completely from scratch specifically for rock crawling performance. This means every aspect of the tyre's design—from the tread blocks to the sidewall geometry—was optimised for maximum grip on unforgiving rock terrain.
- Aggressive Open Tread Pattern — The distinctive tread design features widely spaced blocks that prevent mud and debris from packing into the tyre, maintaining consistent grip even in wet or muddy conditions. The open layout also reduces rolling resistance on looser surfaces.
- Multiple Sipes Per Tread Block — Each individual tread block contains multiple small sipes (thin cuts) that create additional gripping edges and allow the rubber to flex and conform to irregular surfaces. This delivers incredible tread flex whilst maintaining the structural integrity needed for climbing steep slopes.
- Highly Detailed Connected Sidewall Tread — The sidewalls feature intricate, connected tread patterns that extend outward from the main tyre body. This design is engineered specifically for side-hilling performance, ensuring your crawler maintains grip when traversing slopes at extreme angles where traditional tyres would slip.
- Futuristic Stepped Tread Blocks — The innovative stepped block design creates multiple forward-gripping edges at different heights across the tread surface. These stepped edges dig into slick rock surfaces with unmatched efficiency, providing grip where conventional flat-block designs fail.
- Legendary G8 Compound Material — Pro-Line's proprietary G8 rubber compound has been laboratory certified and specifically formulated for rock crawling applications. The G8 material provides excellent grip on a variety of surfaces whilst maintaining the durability needed for extensive terrain exploration. The compound is designed for warmer temperatures and general rock crawling use, offering ultra-long-lasting performance that won't prematurely wear out during extended crawling sessions.
- 4.19" Outer Diameter — The tyres feature a 4.19-inch overall diameter with a 1.4-inch width, providing optimal scaling for 1/10 scale crawlers. This size strikes the perfect balance between ground clearance, traction, and realistic proportions on your scale adventure rig.
- Universal 1.9" Wheel Compatibility — These tyres fit Pro-Line's extensive range of 1.9" wheels, giving you flexibility in choosing the exact wheel design and style that matches your crawler's aesthetic whilst maintaining proven performance.
- Made in the USA Since 1982 — Manufactured in the United States using quality control standards developed over four decades of RC racing and crawling, these tyres represent genuine American engineering excellence that UK RC enthusiasts have come to trust.
- Sold as a Pair — This package includes two complete tyres, allowing you to upgrade either your front and rear, or replace a complete set across multiple crawlers.
- Scale Looks with Performance Engineering — The detailed tread pattern and sidewall design deliver impressive realism on your scale rig, looking at home on the most authentic build. The technical engineering underneath ensures performance matches the appearance.
Technical Performance
The Pro-Line Hyrax G8 1.9" tyres represent the pinnacle of rock crawling tyre engineering, combining aesthetic realism with genuine performance innovation. Built using Pro-Line's legendary G8 rubber compound—a laboratory-certified material specifically developed for rock crawling applications—these tyres deliver exceptional grip across varied terrain types including dry rock, wet surfaces, and loose soil. The G8 compound is optimised for warmer temperature conditions and provides the ultra-long-lasting durability required for extended rock crawling sessions without premature degradation. The 4.19-inch outer diameter and 1.4-inch width dimensions provide optimal scaling for 1/10 scale crawlers, ensuring proportions remain realistic whilst delivering the mechanical advantage needed for serious climbing performance. The innovative stepped tread block design creates multiple gripping edges that dig into unforgiving rock surfaces, whilst the multiple sipes within each block allow the rubber to flex and conform to irregular terrain whilst maintaining structural integrity. The highly detailed sidewall tread pattern specifically addresses one of the most challenging aspects of scale crawling: side-hilling performance, where vehicles traverse slopes at extreme angles. Traditional tyre designs struggle in these situations, but the Hyrax's connected sidewall tread pattern provides the grip necessary to maintain control on steep angled climbs. The open, aggressive tread pattern prevents mud, clay, and debris from packing into the grooves—a critical feature for maintaining consistent performance when crawling wet or muddy terrain. These tyres have been engineered for compatibility with Pro-Line's complete range of 1.9" wheels, giving builders the freedom to choose their preferred wheel design without compromising tyre performance. Class 1 legality ensures these tyres meet all competition regulations, making them suitable for organised events across the UK and internationally.
