J.T. Brooks Automatic Tire Deflators PRO (ATDP4)

This item is now discontinued and has been replaced by the new J.T. Brooks Automatic Tire Deflators PRO II.

The differences between the new PRO II and older PRO are:

• PRO II is up to 30% faster than PRO
• larger activation knob on PRO II to prevent inadvertent loss of lock ring
• more legible PSI scale on PRO II

The older PRO deflators remain excellent and there is really need to replace them if that is what you already have.  While the PRO II Deflators may be faster, you will find that you are never the last one in your group to air down because you are airing down all four times at once.  So deflating at faster than even PRO speeds will just mean more waiting for your mates to finish.

An alternative to the Brooks Deflators is the Over-Sand Fully Adjustable Automatic Tire Deflators, which like the Brooks adjust by a scale rather than trial and error.

If you prefer to air down with a conventional deflator, or you want to minimize your gear by combining your inflator and deflator into a single tool, take a look at the ARB Digital Tire Inflator/Deflator.

No matter which method you use to air down, you will have to air up before hitting the highway and will require onboard air on your vehicle.  You will also require onboard air to repair flat tires, which will likely be 90% of your trail fixes.
