Why every 4x4 needs a 12V air compressor

UK off-roading often means adjusting tyre pressures for mud, sand or rocks. A compressor lets you air down for grip, then reinflate for road driving. Other uses include:

  • Inflating tyres (standard and oversized 35″+)
  • Powering air lockers
  • Operating air tools
  • Emergency tyre repairs

ARB Comparison – How TRE4x4 & XT stack up

ARB is well-known in the UK for compressors. However, TRE4x4 and XT Automotive now offer equally strong performance, often at more competitive prices. For example:

  • ARB Twin (174L/min) vs TRE4x4 Twin (178L/min) – similar performance, better value with TRE4x4.
  • ARB Portable Single vs XT Single – XT delivers higher 160L/min flow vs typical ARB outputs.

This makes TRE4x4 and XT Automotive the smart choice for UK 4x4 owners looking for performance and reliability at the best price.
