1. An apparatus, comprising: at least one onboard stereoscopic imaging unit (SIU) mounted for each vehicle tire, configured to couple with a vehicle tire and operative to capture a plurality of three-dimensional tire tread image pairs, a plurality of three-dimensional outer tire sidewall image pairs, and a plurality of three-dimensional inner tire sidewall image pairs;an image processing code operative to process the plurality of three-dimensional tire tread image pairs, the plurality of three-dimensional outer tire sidewall image pairs, and the plurality of three-dimensional inner tire sidewall image pairs for a tire inspection and a detection of tire condition defects;at least one image processor and hardware control unit (IPHWCU) operative to store and run the image processing code;a program instruction code operative to run the IPHWCU and host the image processing code, wherein the program instruction code provides hardware circuit interfaces drivers to communicate with the SIU and other interface circuits;a physical transmission media operative to couple with the at least one SIU on a first distal end and operative to couple with the at least one IPHWCU on a second distal end for transmitting image pairs; anda code configured to execute a service request upon the detection of tire condition defects, wherein the service request triggers a tire maintenance operation for a vehicle. 2. The apparatus according to claim 1, further comprising an accelerometer configured to trigger the IPHWCU to capture image pairs upon measuring a G-force above a substantial threshold, wherein the IPHWCU captures a plurality of three-dimensional tire tread image pairs, a plurality of three-dimensional outer tire sidewall image pairs and a plurality of three-dimensional inner tire sidewall image pairs to inspect tires for damage from the G-force above a substantial threshold. 3. The apparatus according to claim 1, wherein the vehicle is an autonomous self-driving vehicle. 4. The apparatus according to claim 3, further comprising a 5G radio frequency (RF) communications unit coupled with said at least one image processor and hardware control unit and operative to communicate with an external network for vehicle insurance compliance. 5. The apparatus according to claim 4, further comprising a camera lighting device operative to couple with said at least one stereoscopic imaging unit SIU for illuminating vehicle tire treads and tire sidewalls; non-volatile memory configured to store the tire inspection and the detection of tire condition defects;the stereoscopic imaging unit SIU uses CMOS image sensors; anda power supply circuitry supplying direct-current (DC) voltage from a vehicle battery operative to power said apparatus. 6. The apparatus according to claim 5, further comprising a display configured to execute a service request, wherein the service request triggers a vehicle tire maintenance operation. 7. The apparatus according to claim 6, further comprising an IP67 water resistance rating and an operating temperature range substantially between −40° C. to 125° C. 8. A method of imaging and inspection of vehicle tire treads and sidewalls comprising the steps of: capturing an outer sidewall as a first three-dimensional image pair and operative to transfer the first three-dimensional image pair to at least one image processor and hardware control unit (IPHWCU);capturing an inner sidewall as a second three-dimensional image pair and operative to transfer the second three-dimensional image pair to at least one IPHWCU;capturing a tread as a third three-dimensional image pair and operative to transfer the third three-dimensional image pair to at least one IPHWCU;processing said first three-dimensional image pair, said second three-dimensional image pair and said third three-dimensional image pair in at least one IPHWCU utilizing image processing software for inspecting tires;detecting tire condition defects in said first three-dimensional image pair, said three-dimensional second image pair and said third three-dimensional image pair;recording a tire status information to a non-volatile memory configured to store a tire inspection and a detection of tire condition defects data; andtriggering a service request for a tire maintenance service for a vehicle. 9. The method of claim 8, further comprising the steps of: communicating to a vehicle display tire status information; anddisplaying tire status information for a vehicle safety compliance. 10. The method of claim 9, further comprising the step of: recording the tire status information to a non-volatile memory configured to store a tire inspection and a detection of tire condition defects data for an insurance compliance policy and as a defense against legal actions. 11. The method of claim 8, further comprising the steps of: capturing an image comprising a sidewall tire date of tire (DOT) code;checking the DOT code for a manufacturer tire recall database via a network connection;alerting a vehicle display of the manufacturer tire recall;displaying warning message of the manufacturer tire recall; andsaving the manufacturer tire recall information in non-volatile memory. 12. The method of claim 8, further comprising the steps of; capturing a sidewall tire code;checking a tire date code from a manufacturer tire database;determining if said tire date code is expired;displaying warning message; andsaving said tire date code and tire age information in non-volatile memory. 13. The method of claim 12, further comprising the step of: detecting one-side wear condition triggers a display message for a vehicle alignment, springs, and ball joints service warning. 14. The method of claim 13, further comprising the step of: detecting a flat spot wear condition triggers a display message for a check brakes and replace tire warning. 15. The method of claim 14, further comprising the step of: detecting a cupped wear condition triggers a display message for a worn shock absorber and a faulty suspension system warning. 16. The method of claim 15, wherein the vehicle is from a leasing fleet and the vehicle transmits tire status information to a network as a component of a vehicle fleet management procedure for a safety and insurance compliance inspection. 17. The method of claim 8, wherein the vehicle is an autonomous self-driving vehicle. 18. The method of claim 17, wherein the autonomous self-driving vehicle transmits tire status information to a network as a component of a vehicle fleet management procedure. 19. The method of claim 18, wherein the autonomous self-driving vehicle must pass a safety compliance inspection before driving and receive an insurance compliance approval to proceed. 20. The method according to claim 8, wherein triggering a service request is using a 5G radio frequency (RF) communications network service.
