- In 2003 Bridgestone took a stronger proactive position advocating dry, high purity nitrogen inflation (Should You Stop Putting Air In Your Tires, Vol 8, Issue 3, www.trucktires.com)
- Michelin, BF Goodrich, Uniroyal, Riken, Cavalier issued a joint Technical Bulletin in November, 2003 which stated that, "Michelin supports the use of nitrogen on its ability to better retain air over a period of time".
- Goodyear, in a June 14, 2004 Product Service Bulletin #2004-09 stated, "Goodyear supports the use of nitrogen, as an inflation gas, in all Goodyear, Dunlop, Kelly, and Associate Brand and Private Brand products, based on the ability for the tire to retain pressure for a longer period of time. The use of nitrogen will not affect the tire warranty".
- In 2005, The Retread Information Bureau issued a news release, "Why Inflating Tires With Nitrogen Makes Sense" and included the statement, "By extending the useful life of a tire, retreading offers additional environmental benefits."
- Air Liquide in France claimed a... "25% improvement in tire life since tires stay inflated longer because nitrogen migrates 3 times slower than air and nitrogen eliminates internal oxidation of the tire so more retreads can be achieved." Liquide claimed... 30% savings on tires and fuel.
- In a September 20, 2004 technical article in the largest international rubber industry trade paper, Rubber and Plastics News, Dr. J Baldwin of Ford presented his peer reviewed findings "Passenger Tires Inflated With Nitrogen Age Slower". Some of his conclusions included, "lower permeability than oxygen (better gas mileage), more controlled inflation pressure due to the absence of moisture, expected improvement in structural durability due to significant reduction in rubber oxidation (oxidation caused by air from the cavity being forced into the tire carcass".
- Herzlich, a tire industry consulting Chemical Engineer with 50 years industry experience stated in a Tire Business Article October 24, 2005 that "Nitrogens slower permeability characteristics coupled with its bone-dry nature may partially ameliorate some field abuse conditions, including long term inflation maintenance neglect, improper repairs and certain types of tire pressure monitor malfunctions. Even though high purity nitrogen is no guarantee of performance and will not undo the many forms of damage or abuse that can lead to tire failure, it offers a low cost, risk free and positive service opportunity that has finally become commercially and technically practical".
- Volvo Cars Nederland RV in a press release "Nitrogen in Auto Tires Helps the Environment and Safety. Volvo Prefers Nitrogen in Auto Tires (Volvo Prefereert Stiksof in Autobanden)" Volvo stated that "scientific research has proven that the use of nitrogen as inflation gas for auto tires gives many advantages compared to normal compressed air. A tire with 20% under inflation uses 2 to 3% more fuel than a tire with the proper pressure. Volvo Cars Netherlands expects that the Volvo dealers will follow and implement this environmentally beneficial initiative ... every tire is eligible to be filled with nitrogen." Volvo is a division of Ford Motor Company.
