EnTire is developing revolutionary self-inflating tire

Tires commonly leak slowly and "unnoticeably" during their usage. Almost
half of the vehicles on the road today have at least one tire under inflated
by more then 20%. Although 85 % of drivers are concerned about maintaining
proper tire pressure in their tires, only 25% of them use proper methods and
43% of them do not take an active role in maintaining their tire pressure.

EnTire is a patented system, which responds to tire pressure related safety
and economic issues in a simple and elegant manner – tire equipped with the
EnTire system keep itself properly inflated simply by tire use. Tires with
the EnTire inflation system utilize the motion of the tire to maintain small
"unnoticeable" leaks while driving. The EnTire system is also able to
eliminate the loss of air pressure caused by small perforations in the tire
that may occur while driving and would otherwise cause rapid deflation of
the tire. After the vehicle is safely parked, EnTire system stops working
and tire equipped with the EnTire system deflates through the perforation on
safe place. Because tires with such minor perforations behave like healthy
tires, driving on the perforated tire causes no additional damage and can be
then repaired with vulcanization or glue.

Currently there are two innovative products being utilized by tire
manufactures. One of products is a tire equipped with an emergency system
that enables the car to drive on a fully deflated tire for a limited time.
Upon deflation the tire carries the weight of the vehicle with a robust
composition wall or an internal support system. The Second product is a
system for monitoring the tire status that informs the driver of the current
tire pressure and temperature and warning the driver if there is a problem
with the tire.

EnTire is an independent, self-managed, self-inflating tire system that will
fill a gap in the tire market today.EnTire complements the two innovative
products described above, and brings additional value to both of them:

In the case of combining EnTire with a run-flat tire, EnTire will compensate
for small leaks and perforations while the run-flat tire will compensate for
immense tire damage. Tires with the run-flat system usually have very robust
walls and more room for integration of the EnTire system.
The Tire Monitoring System combined with EnTire could be used not only to
inform the driver of the tire status, but also could supply information to
an electronically managed valve if such a valve was used as a part of
EnTire. In the case of a typical perforation while driving, EnTire would
maintain proper tire pressure while Tire Monitoring System would warn the
driver that the tire may will need to be repaired. Such combination would
also enable a controlled EnTire inflation or controlled EnTire deflation.
Pressure decrease is necessary for some types of vehicles including
off-roads, military vehicles or trucks.

EnTire would increase the accuracy of the Indirect Tire Monitoring Systems.
The Indirect Monitoring System measures differences in the rotation speed of
the tires, which indicates a difference in pressure of tires and can give
inaccurate readings when two tires are equally under inflated. EnTire would
radically decrease the possibility of two tires being equally under
inflated.

The goal of EnTire development is to create a simple and reliable solution
that will enable permanent correct tire pressure. There are many
possibilities as to how the final EnTire product might be implemented. One
option is to integrate the EnTire system into new tires; another option is
to integrate the EnTire system into a used tire during re-treading along
with several other options. Each one of these options will be investigated
in order to provide the best possible scenario for safety and economic
concerns along market and industry requirements.

With the EnTire system, tire producers will be able to set the optimum tire
pressure for entire life of their tire, resulting in safer and less
expensive automobile usage.
Tire producers will be able to offer an entire product that maintains itself
for the utmost safety and comfort.
