to dTPMS, more sensitive to the influences of different tires and external influences like road surfaces and driving speed or style. The reset procedure, followed by an automatic learning phase of typically 20 to 60 minutes of driving under which the iTPMS learns and stores the reference parameters before it becomes fully active, cancels out many, but not all of these. As iTPMS do not involve any additional hardware, spare parts, electronic/toxic waste, or service (beyond the regular reset), they are regarded as easy to handle and customer friendly. As mentioned however, the sensors must be reset every time changes are done to the tire setup, and some consumers do not wish to have this added responsibility.

so-called "run-flat warning systems" were introduced. These are most often first generation, purely roll-radius based iTPMS, which ensure that run-flat tires are not used beyond their limitations, usually 80 km/h (50 mph) and 80 km (50 miles) driving distance. The iTPMS market has progressed as well. Indirect TPMS are able to detect under-inflation through combined use of roll radius and spectrum analysis and hence four-wheel monitoring has become feasible. With this breakthrough, meeting the legal requirements is possible also with iTPMS.

also measure and alert temperatures of the tire as well. These systems can identify under-inflation for each individual tire. Although the systems vary in transmitting options, many TPMS products (both OEM and aftermarket) can display realtime, individual tire pressures whether the vehicle is moving or parked. There are many different solutions, but all of them have to face the problems of exposure to hostile environments. The majority are powered by batteries, which limit their useful life. Some sensors utilise a

pressure sensors in the wheels. First-generation iTPMS systems are based on the principle that under-inflated tires have a slightly smaller diameter (and hence higher angular velocity) than a correctly inflated one. These differences are measurable through the wheel speed sensors of ABS/ESC systems. Second generation iTPMS can also detect simultaneous under-inflation in up to all four tires using spectrum analysis of individual wheels, which can be realized in software using advanced signal processing techniques.

drags the lower pressured tire 2.5 metres per kilometre (13 feet per mile). Moreover, running a tire even briefly on inadequate pressure breaks down the casing and prevents the ability to retread. Not all sudden tire failures are caused by under-inflation. Structural damages caused, for example, by hitting sharp curbs or potholes, can also lead to sudden tire failures, even a certain time after the damaging incident. These cannot be proactively detected by any TPMS.

for new models and on June 30, 2014 for existing models". Japan is expected to adopt European Union legislation approximately one year after European Union implementation. Further countries to make TPMS mandatory include Russia, Indonesia, the Philippines, Israel, Malaysia and Turkey. After the TREAD Act was passed, many companies responded to the market opportunity by releasing TPMS products using battery-powered radio transmitter wheel modules.

mechanical overload caused by overheating and subsequent, sudden destruction of the tire itself. Additionally, fuel efficiency and tire wear are severely affected by under-inflation. Tires do not only leak air if punctured, they also leak air naturally, and over a year, even a typical new, properly mounted tire can lose from 20 to 60

not transmit information when parked (which eliminates spare tire monitoring) or apply a more power expensive two-way communication which enables wake-up of the sensor. For OEM auto dTPMS units to work properly, they need to recognize the sensor positions and must ignore the signals from other vehicles.

TPMS became obligatory for every vehicle under 3.5t sold after 2013. Later in 2015, every vehicle had to have TPMS regardless of its size. In 2011, Hyundai Mobis successfully developed the TPMS and first applied it in the Veloster. As a result, the sensor's power usage is about 30% lower than that of
