Tire tread integrity monitoring system and method
First Claim
1. A tire monitoring system comprising:
- a sensor to monitor a parameter of a tire of a vehicle;
a memory device to receive signals from said sensor indicative of said parameter over time and to store said received signals; and
a processing device to couple to said memory device and to compare information regarding said parameter over time with a reference threshold of said parameter over time.

Abstract
A tire monitoring method and apparatus is provided to predict tire tread separation for a tire on a wheel of a vehicle. This may involve monitoring a parameter of a tire of a vehicle over time and comparing information regarding the monitored parameter (over time) with a reference threshold value of the parameter (over time). The method may also include providing information to a driver based on the comparison. The parameter may be acceleration (axial, radial or longitudinal) along an axis of the tire. The parameter may also be tire imbalance, temperature inside the tire, speed of the tire, load and/or pressure, for example. Information regarding the comparison may be transmitted to a driver if the monitored parameter exceeds the reference threshold value for a predetermined amount of time.
