H89151

Overview

The HoBao 1/8th Dual Compound Inserts (4) (Hard Shoulders) H89151 are premium tyre inserts designed specifically for competitive 1/8 scale RC on-road racing. These inserts are essential components for serious RC enthusiasts and competitors across the UK who demand maximum grip, stability and control on both smooth and textured racing surfaces. Hard shoulder inserts provide a firmer sidewall construction that benefits drivers who require precise handling characteristics, reduced tyre flex and improved cornering performance during high-speed racing sequences.

Whether you're preparing your HoBao Extreme VTE2 1/8 on-road racer for club competitions or weekend practice sessions, these dual compound inserts deliver the performance advantage you need. The hard shoulder design works in conjunction with softer tyre compounds to create a balanced setup that excels across varying track conditions. For UK-based RC racers and bashers looking to optimise their 1/8 scale on-road RC cars, these inserts represent a worthwhile investment in your racing setup.

HoBao is recognised globally for manufacturing precision RC components and complete vehicles that compete at the highest levels of the sport. The H89151 inserts are OEM components that meet the exacting standards demanded by professional and amateur racing teams alike. If you're serious about extracting maximum performance from your 1/8 scale on-road RC vehicle, upgrading to quality tyre inserts like these will make a noticeable difference in handling, consistency and lap times.

Key Features

• Hard Shoulder Construction — The hard shoulder design provides increased sidewall stiffness and support, reducing unwanted tyre flex during aggressive cornering and high-speed manoeuvres, resulting in more predictable and responsive handling characteristics.
• Dual Compound Technology — These inserts utilise dual compound construction to balance grip and durability, combining softer contact patches with harder shoulder sections that work together to deliver optimal performance across different track conditions.
• Set of Four Inserts — This pack includes four complete inserts, providing full coverage for all four tyres on your 1/8 scale RC on-road vehicle, ensuring consistent handling across the entire chassis.
• HoBao OEM Quality — Manufactured by HoBao, a leading RC component manufacturer, these inserts are engineered to precise tolerances and specifications, guaranteeing fitment and performance with HoBao 1/8 scale vehicles and compatible platforms.
• Competitive Racing Application — Designed specifically for on-road racing rather than general bashing, these inserts are ideal for competitors seeking to gain every marginal performance advantage in club races, regional competitions and serious practice sessions.
• Improved Cornering Stability — The reduced flex provided by hard shoulders delivers more consistent cornering grip and more predictable tyre behaviour, allowing drivers to maintain higher speeds through technical corner sequences with greater confidence.

Technical Performance

The HoBao 1/8th Dual Compound Inserts (4) (Hard Shoulders) H89151 represent precision engineering at the component level for competitive 1/8 scale on-road RC racing. These inserts are engineered to work seamlessly with HoBao 1/8 scale platforms, particularly the Extreme VTE2 series, which features an advanced chassis design incorporating lightweight hard anodised aluminium weighing just 390 grams. The inserts' hard shoulder compound provides significantly reduced sidewall flex compared to soft compound inserts, a characteristic that becomes critical when operating at the elevated speeds and aggressive driving angles typical of competitive on-road racing. The dual compound construction ensures that whilst the shoulders provide structural support and reduce deformation during high-load cornering, the tread contact area maintains sufficient grip levels for acceleration, braking and mid-corner traction. When paired with quality on-road racing tyres and properly inflated to recommended pressures, these inserts deliver measurable improvements in lap consistency, reduced understeer characteristics and improved responsiveness to steering inputs. The H89151 specification integrates perfectly with the VTE2's fully adjustable suspension geometry, including its front and rear sway bars, adjustable caster and camber settings, and oil-filled 17mm big bore shocks, allowing drivers to fine-tune their complete setup for maximum performance.

Frequently Asked Questions

• What is the difference between hard shoulder inserts and soft compound inserts for 1/8 scale on-road RC racing? — Hard shoulder inserts provide increased sidewall stiffness and reduced flex during cornering, improving handling consistency and allowing higher corner speeds, whilst soft compound inserts offer maximum grip but more tyre movement. Hard shoulders suit competitive racing and smooth tracks, whilst soft compounds work better for newer drivers or rougher surfaces.
• Are these inserts suitable for the HoBao Extreme VTE2? — Yes, the H89151 inserts are specifically designed for HoBao 1/8 scale on-road vehicles including the Extreme VTE2 1/8 On Road EP roller, which features a lightweight 390-gram hard anodised aluminium chassis and full suspension adjustment capabilities that benefit from performance-oriented tyre setups.
• How do I fit these tyre inserts to my RC tyres? — Tyre inserts are fitted inside your racing tyres before mounting them onto the rims. You will need quality tyre glue and tyre mounting tools to install them correctly. Most RC racers apply tyre glue to the inside of the tyre and the outer surface of the insert, then roll and press the insert into position, allowing the adhesive to cure fully before mounting the tyre onto the wheel rim.
• What is the benefit of upgrading to OEM HoBao inserts? — OEM inserts like the H89151 are engineered to match your vehicle's suspension geometry and performance targets, providing predictable handling that allows you to make more confident driving inputs and achieve faster, more consistent lap times compared to generic alternatives.
• Can these inserts be used with other 1/8 scale on-road RC vehicles? — These inserts are specifically designed for HoBao 1/8 scale on-road vehicles. Whilst they may be compatible with other 1/8 scale vehicles with identical tyre dimensions, fitment and performance cannot be guaranteed outside the HoBao platform.
• Are these suitable for beginners? — These are competitive racing components designed for drivers who understand setup tuning and are seeking performance optimisation. Whilst not exclusive to experienced drivers, they represent an investment that offers greater benefit to racers who understand how tyre construction affects handling and can consistently drive at higher levels.
