The pilot reported he found an incorrect tire installed on [Aircraft X]. The findings were reported to ZZZ Maintenance on 06/XX/19 and a log page was created changing out tire and wheel assembly correcting the problem that same day. I was notified today that I may have incorrectly installed this tire on 06/XY/19 as I replaced the wheel and tire assembly due to cord showing. After looking into and researching what may have been wrong with the tire or installation I discovered that the [Aircraft X]is a [Large Transport] with carbon brakes and by closely looking at my parts tag I installed a tire and wheel assembly for a [Large Transport] Carbon. I can recall when I changed this tire I needed a carbon assembly; and also knowing that; the wheels for the [aircraft] I needed were marked with green dust covers; as mine was. I installed the wheel and tire assembly correctly but unknowingly installed the wrong part number. I recall pulling the tire and wheel assembly from the proper rack and noting the green dust covers on it. I can't recall checking for the correct part number and this is where I made my error. I do recognize my mistake and the importance of following all proper steps in part identifying and inspecting selected parts and part numbers to be installed.	While I was retracing my steps trying to remember and think about what may have happened when changing this tire assembly I walked the process in terminal two of pulling a tire assembly from the tire storage area. What I found was shocking! The location where [Large Transport] carbon tires are kept I noted one in stock and it had installed on it one side dust cover yellow and the other side dust cover green. Located next to this are more stored tires with two signs on the same wall located right below each other. One reads [Large Transport] and below that sign another sign reads [Large Transport]. All the tires located in this area had yellow dust covers. All the [Large Transport] should have green covers and they did not. The terminal two tire storage area needs to be remarked and reorganized. There is room for improvement in this area and I would be more than happy to assist with making any changes to improve this process.
Maintenance Technician reports that aircraft tire storage area has signage that is confusing.
