A tire inflator having an air compressor to inflate a tire to a predetermined pressure threshold. A central OBD module plugged into in a vehicle uses a short-range radio to transmit to the inflator the predetermined pressure threshold fit for a vehicle. An OBD vehicle bus reader can obtain a VIN of an associated vehicle model. A predetermined tire pressure threshold memory contains a predetermined look-up table of tire pressure thresholds for models. A processor uses the VIN to identify the vehicle model in the look-up table to select the one of the predetermined tire pressure thresholds including a spare tire pressure threshold. A short-range radio wirelessly transmits the looked-up tire pressure threshold including a spare tire pressure threshold to each inflator. The tire inflator has an optical moisture sensor on air inlet or air outlet. The air compressor is disabled when moisture is detected.

A direct tire data collection and communication device is adapted for use in a pneumatic vehicle tire. The device incorporates a tire-mounted electronics module comprising a microcontroller, and at least one tire property sensor in electronic communication with the microcontroller and capable of measuring at least one operational property of the vehicle tire. The threshold operational property value defines a positive tire safety condition and a negative tire safety condition. The electronics module calculates accumulated travel data of the vehicle tire while in the negative tire safety condition. A transmitter transmits the travel data to an electronic remote terminal.

Provided is a tire information acquisition device that includes a sensor unit including a sensor that acquires tire information, a first band that is for fixing the sensor unit (1) to a rim (R) and has an adjustable band circumferential length by fastening another end reversibly with a fastening portion provided to one end, and at least one second band that fastens the sensor unit and the first band integrally.

An in-tire electric device having a bracket and an electric circuit unit detachably held by the bracket includes: an engagement protrusion and an engagement hole provided on the electric circuit unit and the bracket to engage with each other to restrict, through a two-step operation where the electric circuit unit is moved in a first direction and then moved or rotated in a second direction intersecting the first direction, all movements and rotations except for a reverse of the second direction; a retainer mounted on the bracket from a direction intersecting the second direction and facing the electric circuit unit in the second direction to restrict the electric circuit unit from moving in the second direction; and retainer locking portions formed on the bracket and the retainer and engage with each other by elastic deformation of one of the retainer locking portions to lock the retainer to the bracket.

A tire pressure sensor mounting system for mounting a tire pressure sensor directly to a wheel rim. A mounting base is disposed on the wheel rim. A linear rim strap groove is disposed across a top surface of the mounting base. A plurality of side strap through-slots is transversely disposed through the side surfaces of the mounting base. A portion of a rim strap is disposed in the rim strap groove. A first locking mechanism tightly encloses the rim strap around the wheel rim to secure the mounting base on the wheel rim. A portion of a side strap is disposed through the side strap through-slot. A second locking mechanism locks the side strap around the tire pressure sensor to secure the tire pressure sensor on the mounting base.

Disclosed is a device for attaching a sensor for a TPMS. The device for attaching a sensor for a TPMS includes: a module housing including a sensor module for a TPMS; a binding unit including a wire that is long enough to be wrapped on a wheel circumference portion of a vehicle and a rotation shaft installed in the module housing to wind or unwind the wire by a normal/reverse rotation; an engaging and fixing unit including an engaged groove and an engaged protrusion formed to generate an engaging and contacting force while being able to control an unwinding rotation corresponding to the rotation shaft of the binding unit; and a rotation unit disposed to rotate the rotation shaft of the binding unit and formed to release an engaging and contacting state of the engaging and fixing unit in connection with the rotating.

A combination vehicle tire sensor assembly and in-tire wheel balancer is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. The combination comprises a flexible mounting cable secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable inside the pneumatic tire a spaced distance from the sensor assembly. A substantially hollow balancer belt resides inside the pneumatic tire adjacent the sensor assembly and counterweight, and defines a circumferentially-extending exterior groove designed for receiving and locating said mounting cable, and a circumferentially-extending interior cavity adapted for loosely containing a wheel-balancing medium.

A bracket that is pressed against and fixed to an outer peripheral surface of a rim of a tire wheel by a belt wound around the outer peripheral surface of the rim, and detachably holds an electric circuit unit includes: a pair of rim contact portions that are provided at both ends in a circumferential direction of the rim in a rim facing surface facing the outer peripheral surface of the rim, and come into contact with the outer peripheral surface of the rim in such a way as to cause a portion between the both ends to be spaced apart from the outer peripheral surface of the rim.

An in-tire vehicle tire sensor assembly is adapted for residing inside a pneumatic tire mounted on a wheel rim of a motor vehicle. A flexible mounting cable is secured to the sensor assembly, and adapted for extending circumferentially within an annular space formed between the tire and wheel rim. A counterweight is secured to the mounting cable a spaced distance from the sensor assembly.

An apparatus for monitoring a tire and/or a wheel including a sensor system; a wireless communication interface; a processor connected to the sensor system and the wireless communication interface; a power source; and a mounting system for attaching the apparatus to a wheel. The mounting system is configured to allow movement of the sensor system relative to the wheel in use.
