Self-Inflating tires are a new technology, still in the testing phase. They are only available for limited commercial applications, and only for the purpose of testing, at this time. It is expected this testing period will last approximately 18 months. After which, if the testing is successful, the technology will be available for passenger tires.
Under inflation causes poor fuel economy and reduced tread life. The additional cost of this product, along with the convenience of not having to maintain the air pressure yourself, will be the deciding factors if this product is for you. — Will C. Sparks, owner
