America's Leading Dual Tire Pressure Equalization System Saves You Time and Money.

Dual tires have a set of problems all their own. In motion, the inner tire's temperature increases due to in-board brakes and poor air circulation. This causes increased air pressure, which expands the inner tire's diameter. As a result, the dual tire configuration is now distorted- the diameters are unequal. Crossfire is a pressure equalizing and monitoring valve that is mounted between dual tires. It bolts easily to the lug, hub cap, or drive axle end. Properly mounted, air freely flows from one tire to the other, maintaining equal tire pressure and load distribution.


The Crossfire Dual Tire Pressure Equalization system:
  • Maximizes tire life
  • Decreases rolling resistance for increased fuel mileage
  • Cuts maintenance time due to single-point inflation and the visual pressure gauge
  • Improves stability, braking and overall safety
  • Installs in minutes and requires little maintenance
  • Pays for itself in less than a year
  • American-made and guaranteed for two years


  • This Crossfire System is for ONE dual tire set and comes with:
  • 2 Stainless Steel Hoses, one with straight fitting and one with 180° fitting
  • 3 mounting bracket types:
      Bracket A: installed on the 5/8" or 3/4" drive axle bolts of both disc and spoke wheels. If the wheel has a hubcap, it can be snapped on over the bracket.
      Bracket B: mounts directly on the 1-1/4" lug bolt.
      Bracket T: mounts on the 1/4" bolt that secures the hub cap to either a disc or spoke wheel.
