This photograph shows product packaging and literature from Oasis Manufacturing (Oasis Off Road Mfg) of Laguna Hills, California, makers of hi-performance DC air systems and automatic tire deflators. The header card lists the company address (22971 Triton Way, Unit F, Laguna Hills, CA 92653), phone numbers (888-96-OASIS toll free, 949-768-4311), and website (www.oasismfg.com). Inside the sealed bag is a sliding 'Tire Deflation Guide' card advertising that you can 'air down while you drive with Automatic Tire Deflators.' The guide is a slide-rule style chart: the user selects a tire size from a list of sixteen common off-road sizes (from 215/75R15 through 38x15.50R15 and 225/75R16 through 295/75R16), then reads suggested tire pressure in psi across gross vehicle weight columns from 2,000 to 8,000 lbs. Visible in the window for the selected size are pressures such as 11, 13, and 15 psi, with 'N/R' (Not Recommended) shown for heavier vehicle weights. Fax number (949) 768-4677 and website oasis-off-road.com are also printed. The document is undated and is generic accessory literature, not vehicle-specific, so it does not contradict its association with a 1990 Ford Bronco.
