How Overdue is Your Tyre Pressure Check?

LINKOPING, Sweden, October 15, 2012 /PRNewswire/ --
A recent Swedish study by TNS Sifo 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, CO emission and2
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: 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.

study
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 by NIRA, without additional sensors (indirect, or iTPMS). They are much cheaper, but
do they work?
TÜV SÜD has tested TPI by NIRA twice, along with a competitor's product. The results 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 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."
