No ei todellakaan näin. Ja eihän nelivedolla sudi muutenkaan.
No kuinkas sitten? Jos asiasta kerran tietää niin kait pystyy antamaan muutakin kuin vaan leväperäisen vastauksen? Lisäksi missä mainitsin sanallakaan nelivedosta? Siitä miten sutii missä, milloin ja monellako renkaalla voidaan jatkaa ilomielin siinä toisessa topikissa, eikös?
.
Mutta itse asiaan, seuraavanlaisia esimerkiksi tuli vastaan Googlettamalla niin siitä vaan heräsi mielenkiintoni;
"Unfortunately, indirect tire pressure monitoring systems have several shortcomings. Indirect systems won't tell the drivers which tire is low on pressure, and won't warn the driver if all four tires are losing pressure at the same rate (as occurs during the fall and winter months when ambient temperatures get colder).
Additionally, our current experience with indirect systems indicates that they can generate frequent false warnings. We have found that false warnings may occur when the tires spin on wet, icy and snow-covered roads."
"Of the two, direct TPMS is more accurate, especially since indirect TPMS may not detect a problem if all four tires lose air at approximately the same time,
or it may generate a false reading if one tire spins on ice."
"Indirect TPMS is a much less expensive system than direct TPMS to add to a vehicle because it
doesn’t require any pressure sensors or other new hardware. It only requires reprogramming the ABS system to turn on a low pressure warning indicator when it detects a change in wheel speed that may be the result of a low tire.
Unfortunately, indirect TPMS may give false alarms if a tire is slipping for other reasons (such as an icy or slick road)."
