reason i ask is because i measured mine at like 1/16 to 1/8 over 10” which would put me right at the discard spec assuming .090 over 10”. Also i noticed my shoes werent wearing as much at the top and bottom of the shoe. Theres about a inch on the top and bottom of the shoes where it doesnt really look like they have wore. Of course the car may get driven 15-20 miles a week or every two weeks so not a lot of braking going on
