Seriously...TPMS?

[GManBart]

[
Seems the government has studied this, and ound that cars with TPMS are more likely to have properly inflated tires....generally, a good thing.

Every person in the USA being granted a million dollars would generally be a good thing too, but it's not the place of the government to make it happen.

...whoops, that remark probably belongs in "friendly politics" delete if necessary...

Well, the NHTSA claims that low tire pressure causes 250,000 accidents annually...that's one for roughly every 1200 people in the country. I'd rather not be the victim in one of those 250K because some moron doesn't check his tires, or can't notice when it's driving strange, so I'm all for anything reasonable that will help reduce those numbers. When you look at what TPMS adds to the cost of a modern car, it seems pretty minor.

I've pulled more bodies, and injured people, out of wrecks than most folks, so I'm somewhat sensitized to the problems caused by stupid people when it comes to their cars. I certainly don't like big government, but when people have stopped taking responsibility for what they do in public, and largely that has already happened, I'm okay with reasonable attempts to at least minimize the damage those stupid people cause. Most people aren't "drivers", they are what I call "steerers"; they get behind the wheel, and do almost nothing but keep the car generally between the lines. If a light on the dash tells them it's time to pull over and get their tires checked, even though they didn't notice it was driving funny, that's a good thing.

I know I was pretty grateful when the light told me I'd picked up a screw in one of my tires on the way to work....I know enough to check my tires, and can feel when things aren't right...it just told me before it got dangerous.

I made a trip to the landfill during my day a few weeks ago. I must have picked a screw. About a mile away from the site I pulled over to check my tires. All looked okay. At my next job, the neighbouring business was a small town automotive repair shop. They fixed my tire during my service call. No down time changing a tire road side, no lost service call. I figure it saved me couple hundred bucks and a pita. I like tpms. I just wish the programming and serviceability was more user friendly.

It would be /could be better if, there were a standard. such as OBD 2. B-4 OBD 2. I think every manufacture had a different method of retrieving codes or different codes. Now ,with the OBD 2 standard, anyone can purchase 1 scan tool that will plug into just about any manufacture's port and read most codes

tire inflation also effects antilock braking an underinflated tire has a smaller diameter than one properly inflated, thus causing bogus wheel speed readings. regardless most people are too inept to check tire pressure themselves.

I've tested my car extensively (many hundreds of times), activating ABS from 115 mph on down, with tire pressures ranging from 16 psi up to 36 psi, ambient temps ranging from 45F up to 108F, and tire temps all over the map... and the ABS does it's thing flawlessly regardless.

PS - The tests were performed in a controlled on-track environment... not on public streets.

How does legislation requiring TPMS insure properly inflated tires and therefore prevent the few accidents caused by under inflated tires?

It doesn't. The same personality of person who drives with low tires, can/will ignore a little reminder icon.

I have a 2013 Chevy truck with TPMS and Onstar. It tells me on the dash display if a tire gets low. After I fill tire tire to the correct pressure and drive it the warning goes away. The next time I check the on board diagnostics it shows what the tire pressure in each tire is.
OnStar runs a diagnostic each month and sends me an Email report. They recently sent me a report that it was time to rotate the tires. I rotated the tires myself but saw no place or way to reset it on the report. The following months diagnostics must have sensed I had rotated the tires since I didn't get a warning to rotate the tires.

invest in CTIS instead

Well I always knew what PMS was but did not know that tires suffered the same symptoms.

Yeah, I thought this thread was going to be about one of the female TBN members' personal problem. But my truck and car is a 1999. And since were are on the subject, how come the modern vehicle doesn't just go ahead and air up the faulty tire?

Thats CTIS

Next time it reminds to rotate your tires, don't do it for a couple months to see if really sees it or just a one time reminder. Just for curiosity.
