Heat softens the bond you just made
Pressure-sensitive adhesive has a working range. Cold makes it stiff; heat makes it soft. A weight applied to a hot wheel bonds fast and feels solid, and then the wheel keeps living at highway temperature, where a softened adhesive can creep. Add cornering loads and the weight migrates before it lets go.
The failure looks different from winter's. Winter weights pop off clean. Summer weights slide first, and a weight that has moved half an inch is already a comeback, it just has not called you yet.
