TRX9469X

Overview

The Traxxas Tyre Inserts, moulded (2) (for #9475 rear Tyres) (+2 firmness) TRX9469X are precision-engineered foam inserts designed specifically for drag racing enthusiasts and serious RC competitors across the UK who demand maximum customisation and performance tuning. Whether you're setting up your 1/10 scale drag racing machine for competition or experimenting with different track conditions, these stiffer moulded-foam inserts provide the extra firmness needed to fine-tune your tyre setup and achieve consistent, predictable handling characteristics.

As an authorised Traxxas retailer, RC Model Shop supplies genuine OEM parts that meet the manufacturer's exacting standards. These rear tyre inserts are engineered with precision moulding techniques to ensure consistent performance lap after lap. The +2 firmness rating means they are two steps stiffer than the standard insert, allowing you to dial in your drag racing setup with surgical precision. Whether you're running on a smooth carpet track, a tacky clay surface, or a grip-heavy competition venue, having multiple insert options in your spares box is essential for any serious RC drag racing competitor in the UK.

Drag racing is one of the most demanding disciplines in RC motorsport, and tyre inserts play a crucial role in determining how your vehicle launches off the line and maintains traction throughout the run. These Traxxas moulded inserts are made to last and engineered to deliver the stiffness characteristics you need when your standard setup isn't providing quite enough support for the rear tyre sidewalls. Compatible with #9475 rear tyres, these inserts are the perfect upgrade for anyone looking to expand their tyre tuning options.

Key Features

• Stiffer +2 Firmness Rating — These inserts are two firmness steps stiffer than standard options, giving you access to a wider range of tuning possibilities for different track conditions and racing scenarios. A stiffer insert reduces tyre deformation and sidewall flex, which is critical for consistent drag racing launches and maintaining vehicle stability at high speeds on smooth surfaces.
• Precision Moulded Foam Construction — The moulded-foam design ensures uniform density and consistent performance characteristics across both inserts, eliminating variables that can arise from compressed or hand-packed inserts. This precision engineering means you get reliable, repeatable results every time you swap your inserts between runs.
• Genuine Traxxas OEM Parts — These are factory-manufactured Traxxas components, not third-party copies or alternative brands, ensuring perfect compatibility with your #9475 rear tyres and guaranteeing the exact firmness specifications promised. Buying genuine parts means you avoid fitment issues and performance inconsistencies.
• Pack of Two Inserts — You receive a complete pair of inserts suitable for both rear wheels, so no additional purchases are needed to complete your tyre setup. Having matched pairs ensures consistent left-side and right-side behaviour during acceleration and braking.
• Compatible with #9475 Rear Tyres — These inserts are specifically engineered and tested to work with Traxxas #9475 rear tyres, ensuring optimal tyre profile, grip characteristics and sidewall support. This ensures you're not guessing about compatibility when making your purchase.
• Essential Tuning Tool for Drag Racing — In drag racing, small changes in tyre pressure and insert firmness can make the difference between consistency and inconsistency off the line. Having multiple firmness options available allows you to match your setup to ambient temperature, track surface grip level and your vehicle's power characteristics.

Technical Performance

These moulded-foam tyre inserts represent Traxxas's engineering approach to drag racing tyre tuning. The +2 firmness designation means they fall into the stiffer end of the insert spectrum, designed for applications where standard inserts allow too much sidewall deflection. In 1/10 scale drag racing, the rear tyre inserts directly affect how power is transferred from your motor and gearbox to the track surface during the critical launch phase. A firmer insert reduces squat and maintains a more consistent tyre contact patch, leading to better traction consistency and more predictable launch characteristics. The precision moulded construction ensures that both inserts in the pair have identical density and firmness characteristics, eliminating any left-right asymmetry that could cause handling issues. These inserts work in conjunction with your #9475 rear tyres to create a tunable system where you can adjust overall tyre stiffness without changing tyres completely. For competitive drag racing in the UK, where track conditions vary seasonally and between venues, having a selection of insert firmness options in your spares bag is considered essential. The moulded-foam material is durable and resistant to degradation from repeated use, temperature changes and the stresses of high-acceleration runs.

Frequently Asked Questions

• What are tyre inserts and why do I need them for RC drag racing? — Tyre inserts are foam or cellular supports that fit inside your RC car's tyres to control sidewall flex and maintain tyre shape under acceleration and cornering. In drag racing specifically, inserts are critical because they affect how much your rear tyres squat when launching. A firmer insert reduces squat, maintains a more consistent contact patch, and helps you achieve more consistent acceleration from one run to the next. Different track conditions and ambient temperatures may require different insert firmness levels, which is why having multiple options is valuable.
• What does the +2 firmness rating mean? — The +2 designation indicates these inserts are two firmness steps stiffer than the standard or baseline insert option for this tyre size. If your vehicle currently uses standard inserts and you find that your rear tyres are deforming too much on launch, upgrading to +2 firmness inserts will reduce that deformation and provide a firmer, more supportive feel. This is particularly useful on high-grip surfaces like tacky clay or freshly treated asphalt.
• Are these inserts compatible with my current tyres? — These inserts are specifically designed for Traxxas #9475 rear tyres and are engineered to fit perfectly within that tyre profile and sidewall thickness. Do not attempt to force them into other tyre sizes, as this will compromise both the insert and the tyre. Always verify that your vehicle is fitted with genuine #9475 rear tyres before purchasing these inserts.
• How do I install these tyre inserts? — Installation involves carefully opening your rear tyre bead (usually by gently prying with a flat tool or using a dedicated tyre lever), inserting the moulded foam insert, and then re-seating the tyre bead back onto the rim. Most RC enthusiasts wrap their inserts with tape to help them stay in place during installation. If you're unsure about the installation process, our team at RC Model Shop can provide guidance or assist you in-store.
• How often should I replace my tyre inserts? — Moulded-foam inserts like these are durable and typically last through many racing seasons with proper care. You should replace them if they become compressed, cracked, or permanently deformed. Signs of degradation include noticeable changes in handling characteristics or visible cracks in the foam. For competitive racing, many teams keep multiple sets in different firmness levels and rotate them based on track conditions and temperature.
• Can I use these on a ready to run RC drag car? — Yes, as long as your ready to run RC car is equipped with Traxxas #9475 rear tyres, these inserts are a direct fit. Many ready to run Traxxas vehicles come with standard inserts, so upgrading to +2 firmness gives you a tuning option for better performance on high-grip surfaces or in cooler conditions.
