Tire Pressure Warning Systems: An analysis by AutoSpeed

Soon all new vehicles will require low tire pressure warning systems. The move appears to be justified both on highway-safety and fuel economy grounds. Factory installed, the systems may cost no more than $70 per car. Nevertheless, there are two competing technologies. One relies on individual wheel speed measurements radio-transmitted from sensors in each wheel. The other involves measuring the relative speeds of each tire. When one tire is moving faster than another, the tire is likely underinflated. This article is the first I've seen to cogently explain the strengths and weaknesses of each approach.
