Every offroad traveller knows that your tires perform best when they’re set at a pressure that’s appropriate for the terrain. While highway use calls for a relatively high pressure rate, lowering your air pressure will dramatically improve your 4×4’s traction in a range of off road environments. Compressed air allows you the freedom to adjust the tyre inflation level of your vehicle to suit the conditions. An equally beneficial feature is the ability to re-inflate tires that have been repaired – in gruelling off road conditions, it’s not unusual to get several punctures in one day.
