Those without Tyre Pressure Monitoring System (TPMS) on their vehicles, over 70% of the drivers realize tyre leaks too late that the tyre is damaged beyond repair.<\/p>\n\n\n\n<p>To enhance vehicle safety, the U.S. was the first to legalize TPMS to be equipped on the vehicle in 2005, then followed by the E.U, Japan, South Korea, China and some other. Places that are not mandated by the law, TPMS normally is not included except European made vehicles like Benz and BMW.<\/p>\n\n\n\n<p>I am supposed to convince you to get a set of DIRECT TPMS. But before going into detail, we first need to know the two types of original equipped TPMS in the automobile market. If you do not have any TPMS on your vehicle, you can click <a href=\"#directTPMS\" data-type=\"internal\" data-id=\"#directTPMS\">here<\/a> to direct you to the beneficial of direct TPMS.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">TWO TYPES OF TYRE PRESSURE MONITORING SYSTEM (TPMS)<\/h2>\n\n\n\n<p>Indirect and direct. Both systems assist drivers to inform tyre leaks and meet the law requirement in some countries. However, indirect TPMS comes with several weakness that drivers fail to notice.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Indirect TPMS<\/h3>\n\n\n\n<p>Indirect TPMS does not have any sensor inside the wheel. It leverages on ABS sensor to detect the tyre circumferences. If one of them has tyre leak, circumferences of the tyre changes as compared to opposite tyre, triggering TPMS light on.<\/p>\n\n\n\n<p>Indirect TPMS has one major flaw. If both tyres leak , lets say both drop to 26psi, low pressure light may not get triggered. Furthermore, some vehicle may not trigger the low pressure light even both tyre pressures have 10 psi differences or more. Without knowing the pressure value of a tyre, a driver hardly know what happens in each tyre.<\/p>\n\n\n\n<p>Indirect TPMS met the legal requirement in some countries, providing almost no cost for vehicle owner to maintain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Direct TPMS<\/h3>\n\n\n\n<p>A sensor is installed with tyre nozzle in each rim to detect the tyre pressure value directly. Tyre pressure is shown on the dashboard but not on the older generation vehicle.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"537\" height=\"569\" src=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/direct-TPMS-example.jpg\" alt=\"\" class=\"wp-image-3841\" srcset=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/direct-TPMS-example.jpg 537w, https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/direct-TPMS-example-283x300.jpg 283w\" sizes=\"auto, (max-width: 537px) 100vw, 537px\" \/><\/figure>\n\n\n\n<p>Direct TPMS normally is an option payment on European made vehicles in places like Hong Kong, making it a lot more expensive to purchase as original equipment.<\/p>\n\n\n\n<p>Vehicles with direct TPMS have a minimum tyre pressure value set in the ECU. For instance, Tesla minimum tyre pressure is 38psi. There are two types of direct TPMS available &#8211; Bluetooth TPMS, original equipped in Tesla (for year 2021 and thereafter), and Wifi TPMS, mostly used in other vehicle brands like Toyota, Ford, BMW and more.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><\/td><td>Bluetooth TPMS<\/td><td>Wifi TPMS<\/td><\/tr><tr><td><strong>Means of data transfer<\/strong><\/td><td>Bluetooth<\/td><td>Wifi 315Mhz \/ 433 Mhz<\/td><\/tr><tr><td><strong>Accuracy<\/strong><\/td><td>Depending on the sensor chips.

If you know how to exploit it, it is the greatest weapon in the world that assists your driving and maintains your tyre in good condition. It can shrink the tyre market size, hence no technicians willing to take the initiative to tell you the benefits of TPMS.<\/p>\n\n\n\n<p>Over the years, vehicles equipped with direct TPMS are more likely \u201csave\u201d their punctured tyres beyond repair. Following examples of tyre leak beyond repair. These vehicles do not have direct TPMS installed on the vehicle.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"538\" height=\"717\" src=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/tyre-sidewall-bulb.jpg\" alt=\"\" class=\"wp-image-3830\" srcset=\"https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/tyre-sidewall-bulb.jpg 538w, https:\/\/tyrehood.com\/articles\/wp-content\/uploads\/2026\/09\/tyre-sidewall-bulb-225x300.jpg 225w\" sizes=\"auto, (max-width: 538px) 100vw, 538px\" \/><\/figure>\n\n\n\n<p>Tyre sidewall bulb (bulge) arises as tyre goes too low pressure.
