Deflation Comparison Test

We conducted a deflation comparison test between three methods of deflating your tyres. A Jeep Wrangler with 37″ Tyres was used. The tyres were deflated from 2.2Bar to 0.8Bar. The three methods were:

1. Stick deflation (i.e. pressing a sharp object into the tyre valve to let the air out)

2. Removing the valve core with a valve key, and using a gauge to interrupt the deflation to see if enough air has been left out, until the 0.8Bar was reached

3. Installing the tyFlate quick valves on the tyres and deflate using the tyFlate Control Unit.

The results were as follows:

1. Stick: 4 times 3:40 mins plus walking around the vehicle to each tyre brings this to almost 15minutes

2. Valve key: 1:10 per tyre, plus walking around the vehicle equals 5 minutes

3. tyFlate: 3 mins, including getting in and out of the vehicle, that is, from stop to go a flat 3 minutes.

Added to that, the “style” which the tyFlate brings to the deflation means no sitting or squatting at the wheels, no blown away valve cores, AND all four tyres are at exactly the same pressure.
