Background to the Proposal. Dual Technology
Need for Wheels with Improved Resistance communicated in presentations by the Spanish Army in previous FZ35 Workshop 5 (Maneuver - June 2019).
Spanish companies Advantaria SL and Mixtire Technologies SL have developed the world first mix pneumatic-non pneumatic wheel technology.This techno
MIXTIRE™ patented technology has been originally developed for the civil sector, specially for autonomous vehicles where tire failure is considered the main cause of accidents.

Protected Mix Wheels. Military Applications
Combining this higher tire endurance with armored plates that protect the pneumatic volume provides a breakthrough innovation for its application in the Defense Industry. This technology allows armored vehicles to maintain their speed, increasing their load, stability and driving range, while using wheels resistant to small arm impacts.

Improved Off-Road Performance
Mud and sand terrains pose a relevant difficulty for the mobility of wheeled Armored Fighting Vehicles.

An analysis of off-road characteristics for R20 military tires (395/85R20, 14.00R20 and 16.00R20) shows that R595 MixTire Wheels can increase the Maximum Load and Contact Area, while reducing the Rolling Resistance Coefficient.

Increased Protection and Increased Mobility
MixTire wheels provide a number of advantages for wheeled AFVs performance:
- Pneumatic Volume Armoring.
Increased - Increased Weight of the Vehicle up to 64 ton: Protection Increased Armor and Protection Systems. Increased Armament and Lethality.
- Puncture Resistance.
- Increased Wheel Contact Area: Better Off-Road Performance. Increased Higher Stability. Mobility - Reduced Rolling Resistance Coefficient: Lower Fuel Consumption. Lighter Logistics Footprint. Extended Driving Range.

Future Developments
MixTire Tehnologies and Advantaria are currently working on a number of developments:
- Short Term - Possible Force (Fuerza Posible): 2024 Anti-puncture Mix Wheels for different kind of vehicles. Protected Mix Wheels for 8 wheeled AFV Dragon (Operational Phase).
- Medium Term - Advanced Force (Fuerza Avanzada): 2030 Protected Mix Wheels for 8 wheeled AFV Dragon (Additional Features). Protected Mix Wheels for different kind of vehicles. Protected Mix Wheels for new concept evolved AFV (Initial Development *).
- Long Term - Advantageous Force (Fuerza de Ventaja): 2035 Protected Mix Wheels for new concept evolved AFV (Advanced Development **).
*/** Collaboration with AFVs manufacturers is expected to enable a new concept for wheeled AFVs with increased weight, protection and armament.
