Why are my lugnuts so hard to undo?
• Moisture on the threads or the angled mating surfaces between nut and wheel. If you changed your tires in the rain and water got on the lugs, or you dropped the nuts in a puddle, rust will later form, which can make the nuts very hard to undo without an impact wrench. If at all possible, try to keep rain off the lugs and nuts, or wipe them off before putting the nuts on. Rust can also form simply through disuse. If the wheels are not removed for several years, you can get a simlar effect to having changed a flat tire in the rain. • Overtorquing. Garages are notorious for applying varying torque amounts to the nuts, unless you insist (and watch to make sure) they use a hand torque wrench. You may later notice that the nuts do not all require the same amount of force to remove the next time you take them off yourself. Sometimes overtorquing is caused by tiny-brained owners who think they have to jump on the wrench to tighten the lug nuts. You don’t need 300 lbs on them, and that much m
