Nissan Simplifies Tire Inflation With Its New Warning System
By Jake Lingeman
Nissan will install tire-pressure-measuring systems on its Quest and Altima vehicles that alert the driver filling the tire when it reaches an acceptable level.
Most people don't carry a tire-pressure gauge in their car. A new federal study shows that underinflated tires triple the risk of an accident. Low tires affect braking, accelerating, cornering and fuel economy.
People might be overconfident, considering that almost everyone has a tire-pressure-monitoring system in their car, as long as it's less than five years old. The government mandated the technology in 2005, but it wasn't required until September 2007. Unfortunately, those systems only tell the driver when the tire is low. Most don't say how low, or let the driver know whether he's overfilled the tire.
Nissan's system uses the car's four-way flashers to let the driver know air is coming in. Once the tire is full, the horn beeps once. If the driver puts in too much air, the lights blink faster and the horn beeps three times. When the tire is deflated to a proper level, the horn chirps one more time.
“It's one of those simple slap-your-forehead moments, as to why someone has not thought of it before,” said Vishnu Jayamohan of Nissan product planning and advanced strategy.
I am old school enough to think that that this is another unneeded expensive add-on with potential excessive cost of repair. Drivers/owners should be well aware of the condition of their vehicle and its wear items from tires to brake pads/shoes.
I am realistic enough to know that too many drivers neglect these items until the rim is on the ground.... or in the air after a roll-over.
