How Overdue is Your Tyre Pressure Check?

October 15, 2012

LINKOPING, Sweden, October 15, 2012 /PRNewswire/ –

A recent Swedish study [http://www.niradynamics.se/scripts/resource.php?id=77 ] by TNS
Sifo [http://www.tns-sifo.se ] on tyre pressure has shown that people who check tyre
pressure as often as advised by the car manual are a small minority. A majority still
tolerate increased fuel consumption, CO2 emission and tyre wear, plus degraded vehicle
handling instead of spending a few minutes getting their fingers a little dirty now and
then. How does one persuade drivers to maintain tyre pressure levels? Authorities are
convinced, and the study confirms it, that the only way is to make tyre pressure
monitoring systems (TPMS) mandatory. This was implemented first in the US, and recently in
the EU; TPMS will become mandatory for new vehicle models from next month. Countries like
Korea and Russia have joined in, with China determined to follow soon. But adding features
to vehicles adds cost which has to be covered. With the vehicle industry facing another
crisis, car manufacturers are reluctant to make their products any more expensive. Vehicle
owners have a crystal-clear opinion on this according to the study
[http://www.niradynamics.se/scripts/resource.php?id=77 ]: neither purchase nor maintenance
cost will be accepted. The way forward is to find low-cost, maintenance-free solutions
which simply work in everyday life.

There are two types of system on the market: one with sensors which directly measure
the pressure (dTPMS) and one purely software-based, like TPI
[http://www.niradynamics.se/products/tire_pressure_indicator ] by NIRA
[http://www.niradynamics.se ], without additional sensors (indirect, or iTPMS). They are
much cheaper, but do they work?

TÃœV SÃœD [http://www.tuv-sud.com/home_com ] has tested TPI
[http://www.niradynamics.se/products/tire_pressure_indicator ] by NIRA
[http://www.niradynamics.se ] twice, along with a competitor’s product. The results
[http://www.niradynamics.se/resource.php?tag=itpms_myths_english ] make clear that iTPMS
not only fulfil the legal requirements but have reached a degree of maturity and
performance not considered possible beforehand.

TPMS are effective – but there are drawbacks. If warning thresholds are too strict,
drivers hesitate to take immediate action. The TNS Sifo study
[http://www.niradynamics.se/scripts/resource.php?id=77 ] found that warnings at 20%
pressure loss, the current EU limit and the strictest worldwide, are regarded as too early
by every fourth driver. At 15% pressure loss, more than half of drivers would perceive the
warning as too early and ignore it the next time.

A tire pressure warning is always bad news and making drivers pay for it neither makes
it more popular nor effective.”
