Frequency, warning

First, a question:

What frequency do these TPMS's operate at?

Answer: Frequency of operation depends on the regulations of the communications authorities in each country, but is generally restricted to bands used for "low power short range" communication, i.e., 315 MHz and 433 MHz —Preceding unsigned comment added by 58.167.83.211 (talk • contribs)

Second, a warning:

I have been told by VisiTyre that RF type TPMS's can be interfered with by the automotive's components such as the axles, brakes and rotors, etc. Can anybody collaborate with this?

US DOT NHTSA acknowledges that up to 1 percent of replacement tires make battery powered Radio Frequency based tire pressure systems inoperative (or 2.25 million of the 225 million replacement tires sold annually in the United States). This is due to the ferrous and carbon black content in the tires which causes them to shield the RF energy, much like a Faraday Cage.

Reports are also being made that some RF based TPMS take more than 20 minutes to register tire under-inflation because the vehicle geometry and metal components block or attenuate the low power signal's "radio path" to the receiver electronics.—Preceding unsigned comment added by 58.167.83.211 (talk • contribs)

This page could do with a rewrite?

This Wiki page is in need of a rewrite. There are very few inline citations to reliable third party sources. The information on the page is also not presented in a user friendly manner. Most contributions seem to be from anonymous IP addresses which is okay, but not ideal etc. Where possible original data should be retained though again inline citations could be sourced etc I guess I am offering to do this?

Hi yes this page is a real mess. For such an important subject on Wiki the quality of this article is low and is in need of a rewrite. The format of the page is also in need of a revamp. the inline citations are abused for external links rather than refernce points for additional information.

I started to do some minor copyediting, then got sucked into the abyss that is the rewriting need of this article. I did some work, but after trying to finish up small parts and getting dragged down again, I've just stopped where I am right now. Consequently, some parts of this article remain unclear, needlessly verbose, and/or poorly formatted, and I'm sure I failed to make at least some WP:MOS-recommended changes consistent across the article. I leave the remaining work in the hands of future editors. ~ Jeff Q (talk) 07:34, 4 September 2009 (UTC)

Merge with "tire-pressure monitoring system"?

Merge this page with this one: tire-pressure monitoring system. They're the same title except for the hyphen. Banjodog (talk) 01:35, 15 June 2011 (UTC)

I agree. The page tire-pressure monitoring system covers the same subject but in more depth Imark73 (talk) 08:02, 26 August 2011 (UTC)

Yes this needs to be merged. Who goes about doing this? Jgodbey (talk) 19:20, 5 September 2011 (UTC)

Article bias

Mentioning the advantages of TPMS without mentioning the disadvantages shows bias in the article. — Preceding unsigned comment added by 173.174.59.205 (talk) 00:14, 11 December 2011 (UTC)

Civics

The Clinton Administration signed the TREAD Act into law. The legislation was done by the 106th Congress. BenFranklinPearce (talk) 22:40, 27 February 2012 (UTC)

Question Re:TMP experts

Who are the experts in the tire pressure monitoring industry? I'm doing some market research on the industry. Thanks in advance for the help. —Preceding unsigned comment added by 76.230.117.206 (talk • contribs)

I've worked in TPM systems since 1998 and know quite a lot about them. What do you need to know? Cwbeal (talk) 10:14, 22 July 2008 (UTC)cwbeal

Please describe the actual pressure sensor. How is pressure translated into an electrical signal? How does the sensor attach both to the internal pressure and the outside air pressure? GoodExplainer

What radio signalling system is used? Put the frequencies mentioned above into the article. Is there a named standard for the radio protocol? How does the receiver obtain good data from many transmissions from 4 tires? GoodExplainer

Unanswered questions

This article basically states the obvious (Tire pressure sensor that sends radio signal to the car - duh!). Questions needing answers:

• Are the sensors vehicle brand specific? Or are there standardized/universal specs?
• Do the sensors have to be "paired" with the vehicle?
• What are the radio frequencies used? What are the protocols?
• Are there any handheld sensor monitors (for example to locate a bad/dead sensor).

Recheck for errors and misinterpretations

The given article contains some errors. Please find and correct it. An example would be the statement, "increased tire wear" in the introductory part. 2409:4073:301:E7B2:240E:7ABD:A60A:78BE (talk) 10:45, 22 January 2022 (UTC)

Benefits - Environmental

A figure for carbon monoxide saving is given. Is this meant to be carbon Dioxide? Whichever it is, it needs to be sourced, and preferrably expressed in SI units with an appropriate multipler rather than billions of pounds. Apostrostomper (talk) 08:17, 6 April 2022 (UTC)

absolute or gauge?

Do they measure absolute or gauge pressure? Absolute seems easier, but gives the wrong reading at different altitudes. Gauge requires a reference to outside air, which is tricky from inside the tire. Gah4 (talk) 18:19, 30 April 2022 (UTC)

Indirect TPMS, potential creation of new article
