AUBURN HILLS, Mich. (June 7, 2001) — Chrysler Group will offer tire pressure monitors as optional equipment on its 2002 Jeep Grand Cherokee sport-utility vehicle and Chrysler Town & Country and Dodge Grand Caravan mini-vans, becoming the first manufacturer to offer the pressure-based devices on these class vehicles, the company claims.
``We have been studying tire monitoring systems for quite some time and we feel that we have the right systems for our vehicles today, well in advance of TREAD,´´ said Bernard Robertson, senior vice president-engineering technologies and regulatory affairs, in a prepared statement. ``We will move forward to install tire pressure monitoring systems on all of our vehicles.”
TREAD is the Transportation Recall Enhancement, Accountability, and Documentation Act, legislation passed last year that mandates pressure warning systems by 2004.
``A recent survey found that two out of three cars, light trucks and SUVs have at least one significantly under-inflated tire,´´ Mr. Robertson said. ``There are a lot of people driving in potentially dangerous situations. By offering this technology ahead of schedule on a wide variety of our vehicles, we are helping to remind our customers of the importance of proper tire pressure for their safety.´´
Unlike tire pressure monitors that are activated by anti-lock braking systems and measure the rate of a tire´s rotation, pressure-based monitors determine the actual pressure of the tire, Chrysler said. Schrader-Bridgeport will supply the sending units, while Johnson Controls Inc. will supply the receiving units, Chrysler said.
The sensor is attached to the rim of the wheel, flush against the tire. A radio frequency signal emitted from the sensor relays the tire´s pressure to a central receiver. Once a tire becomes significantly under-inflated, a visual and audio warning is given to the driver
Chrysler also will equip its Chrysler 300M and Concorde Limited passenger cars with the pressure monitors.
At this time, Chrysler has no plans to offer run-flat tires on these vehicles, a spokesman said.
