When the wheel nuts are torqued properly, a Wheel-Check can be placed on each wheel nut in a uniform pattern; once a wheel nut has loosened, the attached Wheel-Check will appear out of sequence for easy identification. If a brake binds or a bearing seizes, Wheel-Check says the heat is transferred through the stud and nut; once the temperature exceeds 248˚F, the Wheel-Check will start to blister around the circumference and eventually begin to distort.
The company says 17 sizes are available in custom sizes and colors.
