Crossfire - Truck Tyre Pressure Equalisation System

The Leading Dual Tyre Pressure Equalisation System.

Saves You Time and Money

The Crossfire Dual^TM Tyre Pressure Equalisation system:

maximises tyre life (two sets of Michelin Tyres recently achieved 516,000 km on drive axle of a Scania 40t 4x2 tractive unit, without re-grooving! - see below)
decreases rolling resistance for better fuel consumption
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
easily pays for itself
stainless steel fittings and braided hoses
guaranteed for two years

"I came across this product largely by accident. I monitor the fuel consumption on my trucks closely and I noticed a sudden increase on one of the vehicles (20%). I couldn't understand what had happened until after 6 weeks, I personally checked the tyre pressures. One of the inner tyres on the drive axle was virtually flat (60 psi). The driver (and the service agent) had failed to notice. I estimate this oversight cost me around 500 GBP in extra fuel. I buy most of my fuel abroad so it could have cost me much more! This product gives a constant display of the tyre pressures from a distance. The improved fuel economy was an unexpected bonus and I believe it is due to the decreased rolling resistance."

How Crossfire works
Crossfire is a pressure equalising and monitoring valve that is mounted between dual tyres. It bolts easily to the lug, hub cap, or drive axle end. Properly mounted, air freely flows from one tyre to the other, maintaining equal tyre pressure and load distribution.

To fully appreciate how the Crossfire system can add 20% or more life to your tyres, let's look at a few problems.

Under-inflation
20% under-inflation can cause a minimum 30% loss in tyre life expectancy.

With just a glance from as far away as 20 feet, the Crossfire pressure equalising valve indicates an under-inflation problem.
Over-inflation
20% over-inflation can cause a minimum 10% loss in tyre life expectancy.

The Crossfire pressure equalising valve signals an over-inflation problem which can dramatically shorten tyre life.
Proper Inflation
Mounted correctly, Crossfire's yellow indicator verifies that air is flowing freely from one tyre to the other, equalising the load.

Blowouts and leaks
Crossfire employs a safety feature that automatically isolates the "good" tyre in the event of a blow-out. When a blow-out occurs, the internal safety valve closes immediately with only a slight loss of pressure to the "good" tyre.

In slow leak situations, the valve isolates both tyres after a pressure drop of approximately 10 P.S.I.

The Maths

If d1 = 115 cm
C = 3.142 x 115
C1 = 361.33
and if d2 = 114.8 cm
C = 3.142 x 114.8
C2 = 360.70
The difference in circumference being 0.63 cm
Therefore, every revolution of the wheel the larger tyre must drag the smaller tyre more than half a centimetre!.
