RC4WD Falken 1.7 BI850 1/14 Semi Truck Tyres with Foam Inserts Z-T0218

Overview

The RC4WD Falken 1.7" BI850 1/14 Semi Truck Tyres are officially licensed by Falken and represent a premium choice for 1/14 scale RC truck enthusiasts across the UK. These tyres are engineered specifically for scale trucking applications, bringing authentic Falken branding and realistic aesthetics to your 1/14 scale rig. Whether you're a seasoned RC modeller looking to upgrade your semi truck or someone new to the world of scale RC vehicles, these tyres deliver the quality and performance you'd expect from a brand trusted in both full-size and RC motorsport. RC4WD has developed these tyres using their advanced compound technology to ensure they perform reliably on various surfaces whilst maintaining that all-important scale appearance that serious RC truck builders demand.

These are not generic tyres—they are purpose-built for 1/14 scale semi trucks and come as a matched pair, meaning both tyres are calibrated to perform identically. The inclusion of foam inserts and a Falken decal sheet adds to the authentic scale appearance, allowing you to create a genuinely impressive-looking RC truck build. For anyone searching for quality 1/14 scale tyres online in the UK, the RC4WD Falken BI850 offers the perfect balance of scale realism, proven performance, and genuine manufacturer credentials.

These tyres are specifically designed to work seamlessly with RC4WD wheels, though cross-brand compatibility may vary depending on your setup. If you're building a complete Tamiya RC King Hauler or similar 1/14 scale semi truck, you should be aware that a complete truck requires two sets of these tyres—one set per axle configuration—so plan your purchase accordingly.

Key Features

• Officially Licensed Falken Branding — These tyres carry genuine Falken licensing, meaning you get authentic Falken branding and logos on your RC truck rather than generic imitations, adding genuine scale authenticity and collector value to your build.
• Advanced X4 Medium Compound — RC4WD's proprietary Advanced X4 Medium Compound formula provides a realistic appearance that closely matches the look of real semi truck tyres, whilst delivering dependable road performance across different surfaces and conditions.
• Matched Pair for Consistent Performance — Supplied as a pair, both tyres are engineered to deliver identical performance characteristics, ensuring balanced handling and predictable behaviour on your 1/14 scale truck.
• Foam Inserts Included — Each set includes foam inserts that provide the correct support structure inside the tyres, essential for maintaining tyre shape and ensuring proper fitment on 1.7" semi wheels.
• Falken Decal Sheet Included — A complete Falken decal sheet is provided, allowing you to add authentic Falken logos and branding to your truck for an ultra-realistic scale appearance.
• Optimised for 1/14 Scale Semi Trucks — Designed specifically for 1/14 scale applications, these tyres feature proportions and dimensions that deliver authentic scale appearance on vehicles like the Tamiya RC King Hauler.
• Compatible with RC4WD Wheels — These tyres are engineered to work in harmony with RC4WD's 1.7" semi wheels, providing the best fitment and performance when combined as part of the RC4WD system.

Technical Performance

The RC4WD Falken 1.7" BI850 tyres represent genuine engineering designed for 1/14 scale semi truck applications. With an outer diameter of 3.42 inches (87mm) and a width of 0.90 inches (23mm), these tyres are proportioned to deliver authentic scale appearance on 1/14 vehicles. The inner diameter of 1.701 inches (43.2mm) is engineered to fit standard 1.7" semi wheels, and each tyre weighs a modest 1.37 ounces (38.9g), contributing to overall vehicle balance and handling characteristics. The Advanced X4 Medium Compound used throughout the tyre construction strikes an important balance—it provides a realistic visual appearance that mimics genuine truck tyres whilst delivering consistent performance on various surfaces. Unlike harder compounds that might look less realistic or softer compounds that could wear quickly, the medium compound offers a practical middle ground for the scale trucking enthusiast. The tyre profile is engineered to maintain proper contact patch with the ground, essential for stability in a 1/14 scale truck where weight distribution and handling characteristics matter significantly. When paired with matching foam inserts, the tyres maintain their shape reliably, resisting deformation even under sustained use. RC4WD's commitment to quality engineering means these tyres will deliver predictable handling and durability across multiple scale trucking sessions.

Frequently Asked Questions

• Will these RC4WD Falken tyres fit my 1/14 scale semi truck? — Yes, these tyres are specifically designed for 1.7" semi wheels and are confirmed to fit the popular Tamiya 56336 RC King Hauler Black Edition. The 1.701-inch inner diameter (43.2mm) is engineered for standard 1.7" semi applications. However, RC4WD designs their tyres and wheels to work together as a system, and whilst our tyres may work with other manufacturers' wheels in some cases, we cannot guarantee fitment with non-RC4WD wheels due to varying design methodologies across the industry.
• How many sets of these tyres do I need for a complete truck? — For a complete 1/14 scale semi truck with dual wheels on multiple axles, you will need two sets of this product. One set provides two tyres; a typical complete semi truck configuration requires four tyres, necessitating two sets.
• Are these tyres suitable for beginners building their first 1/14 scale truck? — Absolutely. These tyres are an excellent choice for anyone new to 1/14 scale RC trucking. They're straightforward to fit, come with everything you need to get started (foam inserts and decals included), and the Advanced X4 Medium Compound delivers dependable performance without requiring specialist maintenance or complex setup.
• What makes the Advanced X4 Medium Compound better than other tyre compounds? — The Advanced X4 Medium Compound is specifically formulated to achieve two goals simultaneously: a realistic visual appearance that closely matches genuine truck tyres, and reliable road performance across various surfaces. Unlike harder compounds that might look unrealistic or softer compounds that wear quickly, the medium compound provides an excellent balance, making it ideal for scale trucking enthusiasts who value both authenticity and durability.
• Are these officially licensed Falken tyres? — Yes, these tyres are officially licensed by Falken, the globally recognised tyre manufacturer. The Falken logo and branding are authentic and used under proper licensing to RC4WD, giving you genuine branded products rather than generic imitations.
• Will these tyres work with wheels from other RC manufacturers? — RC4WD tyres and wheels are designed to work optimally together as a system. Whilst our tyres may work with other brand wheels in some cases, fitment and performance cannot be guaranteed due to the different design methodologies used across manufacturers. For best results and assured fitment, we recommend using RC4WD wheels with these tyres.
• What is the scale representation of these tyres? — These are 1/14 scale tyres, meaning they are sized proportionally for 1/14 scale RC trucks. At this scale, the 3.42-inch outer diameter translates to a realistic representation of full-size semi truck tyres.
