Setup and Compatibility
Proper wheel selection is crucial for optimal performance and fitment of your Losi 420 ATX Tires. These tires are designed to be used with specific wheel types depending on your RC vehicle model.
- For Losi LST2 Models: To use these tires specifically on Losi LST2 vehicles, Losi wheels with part numbers LOSB7010 or LOSB7011 are required.
- For Other Monster Trucks (Traxxas, HPI, etc.) and Losi Monster Trucks: For universal application on various monster trucks, including those from Traxxas, HPI, and other Losi monster truck models, use LOSB7012 universal wheels.
Ensure that the chosen wheels are clean and free of debris before mounting the tires. The foam inserts should be placed inside the tire before mounting onto the wheel.
Operating Considerations
The Losi 420 ATX tires are versatile and perform well across a range of surfaces. Consider the following for optimal operation:
- Surface Adaptability: These tires are designed to provide good grip on hard dirt, pavement, and carpet. Adjust your driving style according to the surface conditions.
- Tire Break-in: New tires may require a short break-in period to achieve full grip. Drive cautiously for the first few runs.
- Temperature Effects: Tire performance can be affected by ambient temperature. In colder conditions, tires may be stiffer, while in warmer conditions, they may become softer.
Maintenance
Regular maintenance will extend the life and performance of your Losi 420 ATX Tires.
- Cleaning: After use, especially on dirt or dusty surfaces, clean the tires to remove any accumulated debris. A soft brush and mild soap with water can be used, ensuring to rinse thoroughly and dry completely.
- Storage: Store tires in a cool, dry place away from direct sunlight and extreme temperatures. Prolonged exposure to UV light can degrade rubber compounds.
- Inspection: Periodically inspect tires for cuts, tears, or excessive wear. Replace tires if significant damage is observed to maintain optimal performance and safety.
- Foam Inserts: Check foam inserts for degradation or compression. Worn foam inserts can negatively impact tire performance and should be replaced if necessary.
