What are the Benefits of TPMS?

2 minutesread


Benefits of TPMS:

The dynamic behavior of a tire is closely connected to its inflation pressure. Key factors like braking distance and lateral stability require the inflation pressures to be adjusted and kept as specified by the vehicle manufacturer. Extreme under-inflation can even cause thermal and mechanical overload caused by overheating and subsequent, sudden destruction of the tire itself. Additionally, fuel efficiency and tire wear are severely plagued by under-inflation. Tires don’t only leak air if punctured, but they also leak air naturally, and over a year, even a typical new, properly mounted tire can lose from 20 to 60 kPa (3 to 9 psi), roughly 10% or maybe more of its initial pressure.

The significant advantages of TPMS are summarized as follows:
  1. Fuel savings: Per the GITI, for each 10% of under-inflation on each tire on a vehicle, the tenth reduction in fuel economy will occur. The Department of Transportation estimates that under-inflated tires waste 2 billion US gallons (7,600,000 m3) of fuel annually.
  2. Extended tire life: Under-inflated tires are the quantity one reason for tire failure and contribute to tire disintegration, heat buildup, ply separation, and sidewall/casing breakdowns. Further, a difference of 10 pounds per area unit (69 kPa; 0.69 bar) in pressure on a group of duals drags the lower pressured tire 2.5 meters per kilometer (13 feet per mile). Moreover, running a tire even briefly on inadequate pressure breaks down the casing and prevents the power to retread. It’s important to notice that not all sudden tire failures are caused by under-inflation. Structural damages caused, for instance, by hitting sharp curbs or potholes, also can result in sudden tire failures, even a particular time after the damaging incident. These can not be proactively detected by any TPMS.
  3. Improved safety: Under-inflated tires cause tread separation and tire failure, leading to 40,000 accidents, 33,000 injuries, and over 650 deaths per annum. Further, tires properly inflated add greater stability, handling, and braking efficiencies and supply greater safety for the driving force, the vehicle, the loads, et al. on the road.
  4. Environmental efficiency: Under-inflated tires, as estimated by the Department of Transportation, release over 26 billion kilograms (57.5 billion pounds) of unnecessary carbon-monoxide pollutants into the atmosphere every.


Further statistics include:

The French Sécurité Routière, a road safety organization, estimates that 9% of all road accidents involving fatalities are due to tire under-inflation, and therefore the German DEKRA, a product safety organization, estimated that 41% of accidents with physical injuries are linked to tire problems.

The European Union reports that a median under-inflation of 40 kPa produces a rise in fuel consumption of twenty-two and a decrease of tire lifetime of 25%. the ECU Union concludes that tire under-inflation today is accountable for over 20 million liters of unnecessarily-burned fuel, dumping over 2 million tonnes of CO2 into the atmosphere, and for 200 million tires being prematurely wasted worldwide.

In 2018, a field study on TPMS and tire inflation pressure was published on the UN ECE unit on Brakes and Running Gear (GRRF) homepage. It covered 1,470 randomly selected vehicles in three EU countries with dTPMS, iTPMS, and without TPMS. the most findings are that TPMS fitment reliably prevents severe and dangerous underinflation and hence yields the specified effects for traffic safety, fuel consumption, and emissions. The study also showed that there’s no difference in effectiveness between dTPMS and iTPMS which the TPMS reset function doesn’t present a security risk.
