LOS 1/8 420 ATX 4.1 Tires with Foam (2): LST2, XXL/2 G-LOSB7202

Overview

The LOS 1/8 420 ATX 4.1 Tires with Foam represent premium all-terrain rubber compound engineered for Losi RC vehicles, specifically designed for the LST2 and XXL/2 monster truck platforms. These 1/8 scale tyres come as a pair with integrated foam inserts, offering exceptional versatility across multiple surfaces. Whether you're pushing your RC monster truck across tarmac, carpet, or hard-packed dirt, the ATX compound delivers consistent grip and predictable handling that serious RC enthusiasts across the UK demand. The foam liners are pre-installed, saving you setup time and ensuring perfect fit every time—ideal for competitive racing, weekend bashing, or serious hobby driving.

If you run a Losi LST2 or other compatible monster truck platform, upgrading to quality replacement tyres makes a measurable difference to performance and durability. These are genuine OEM Losi parts, manufactured to exacting standards and trusted by RC racing teams and dedicated bashers alike. The 4.1-inch diameter is perfectly sized for 1/8 scale monster truck racing, delivering the right balance of ground clearance and rolling diameter for optimal vehicle dynamics.

This product is currently discontinued by Losi, making any remaining stock valuable for collectors and restoration projects. If you maintain a Losi LST2 or require replacement tyres for your existing monster truck setup, securing a set of these genuine ATX tyres ensures you have authentic Losi components engineered to work seamlessly with your vehicle.

Key Features

• All-Terrain ATX Compound — The ATX tyre formulation is engineered to deliver exceptional performance across a diverse range of surfaces, including smooth tarmac, indoor carpet racing venues, and hard-packed dirt tracks, making these tyres versatile enough for nearly any RC racing environment or bashing location.
• Pre-Installed Foam Inserts Included — Each tyre in this pair arrives with foam inserts already fitted inside, eliminating the need for separate purchase or time-consuming installation, and guaranteeing proper shock absorption and tyre stability during aggressive cornering and high-speed runs.
• 420 Series Wheel Compatibility — These tyres are engineered to fit all 420 Series wheels from Losi, ensuring seamless fitment on your existing chassis or allowing flexible wheel and tyre combinations across your RC fleet.
• Losi LST2 and XXL/2 Specific Design — Optimised dimensions and sidewall construction make these tyres an ideal replacement for Losi's flagship monster truck platforms, with specific fitment notes for alternative monster truck models from manufacturers including Traxxas and HPI.
• 1/8 Scale Monster Truck Sizing — The 4.1-inch outer diameter is precisely sized for 1/8 scale competition and recreational driving, delivering the correct rolling circumference for accurate speedometer readings and optimal gearing performance.

Technical Performance

These LOS 1/8 420 ATX 4.1 tyres represent carefully engineered rubber compound and construction designed specifically for demanding 1/8 scale monster truck applications. The ATX compound formulation balances grip consistency across asphalt, carpet, and loose dirt surfaces—a critical requirement for drivers who compete at multiple venue types or enjoy bashing anywhere their RC car UK setup allows. The 4.1-inch front and rear diameter suits the LST2 and XXL/2 chassis geometry, maintaining proper weight distribution and suspension geometry that Losi engineered into these vehicles. Pre-installed foam inserts absorb impacts and vibrations during aggressive acceleration and braking, reducing stress on wheel bearings and improving overall drivetrain longevity. The sidewall construction and tread pattern deliver predictable handling through corners and maintain traction during high-speed straights on prepared tracks. Quality Losi engineering ensures these genuine OEM components integrate perfectly with your existing drivetrain, whether you're running the latest brushless RC monster truck setups or maintaining a classic LST2 platform that remains a favourite among UK RC enthusiasts.

Frequently Asked Questions

• Do these LOS 1/8 420 ATX tyres fit my Losi LST2? — Yes, these tyres are engineered specifically for the Losi LST2 monster truck platform. To use them on an LST2, you will require either LOSB7010 or LOSB7011 wheels. If you own a different monster truck from Traxxas, HPI, or another Losi model, you can use these tyres with LOSB7012 universal wheels instead.
• What makes the ATX compound different from other Losi tyre options? — The ATX formulation is an all-terrain compound specifically designed to excel on multiple surfaces including pavement, carpet racing venues, and hard dirt tracks. This versatility makes ATX tyres ideal if you race at different venues or enjoy both track and outdoor bashing with your RC car.
• Are foam inserts already included? — Yes, these tyres arrive with foam inserts pre-installed and ready to use. You do not need to purchase liners separately, and the pre-installed foam ensures correct fitment and optimal shock absorption from the moment you unbox them.
• Is this product still in production? — No, the LOS 1/8 420 ATX 4.1 Tires are discontinued by the manufacturer. If you require replacement tyres for your LST2 or XXL/2, availability may be limited, making current stock particularly valuable for maintaining your existing vehicle or completing a restoration project.
• What is the 4.1-inch measurement? — The 4.1-inch specification refers to the outer diameter of the assembled tyre, which determines rolling circumference and affects speedometer accuracy and gearing performance on your 1/8 scale monster truck.
• Can I use these tyres on other RC vehicles? — These tyres are optimised for Losi LST2 and XXL/2 platforms, though they can work on other monster trucks if you obtain the correct wheel adapters. For Traxxas, HPI, and other Losi monster truck models, you will need LOSB7012 universal wheels to ensure proper fitment.
