DJ, The Smart Tire System, monitors the air pressure to the pound, and the temperature. Very accurate. I would not be without this, especially if I had conventional tires. It has an alarm if pressure falls below a preset pressure. You can scan all four tires in about 2-3 seconds.
If you go the conventional route, you really want to get this,
Here's what can happen to you,
low tire, highway speed, can't really feel it, tire gets very hot, tire sidewall shreads to peices, rim and tire are ruined, allmost wrecked, 1:00 AM in the morning, bad part of town, get home at 3:00 AM
This happened to me, just like that. I will never run a car without this system again. I did feel the car tug a bit when I accellerated, I thought I may have a low tire, when in fact it was down to 10 or lbs. Above that you really can't feel it. I was glad I wasn't in a spirited driving mood. You would have had to feel what it was like when the sidwall shredded.
They run about $300.00 give or take. I've been a dealer on them for about a two years, and have put them in many of my classis cars.
