Wheel studs breaking
I change wheels and tires in spring and fall-- aggressive snow tires for winter. So far, I've broken two wheel studs while using a torque wrench to tighten the lug nuts. They both broke at about 80 ft...

You don't state what your vehicle is. If you are using aftermarket wheels, they may not fit the hub close enough. Meaning the weight of your rig is being supported by the studs. In heavier vehicles, particularly 3/4 ton and higher, the wheels fit the hubs very close. Hence the problems some have removing the wheels on dual wheel setups. Dodge and Ford usually have pretty close to the same hub size, while GM was a little smaller. While the wheels will bolt on all 3, GM had a gap between the hub and wheel. You could bolt the Ford or Dodge wheel on the GM, but not GM on a Ford or Dodge. In an attempt to keep stock down, the aftermarket people will make a wheel to fit all 3 and trailers too. With the weight on the studs, it stresses them and will cause them to fail. In heavy applications, the studs are strictly for clamping force and to keep the wheel from spinning on the hub.
