Why do Toyota lug nuts swell?

Why Toyota Lug Nuts Swell
Swollen Toyota lug nuts are caused by the rust and corrosion between the chrome decorative cap and the actual steel lug nut securing the wheel to the vehicle. This problem is prevalent in some Jeep, Toyota, Ford, Chrysler, and Dodge models. The issue arises from the way the lug nuts are made, with a thin, chrome-plated metal covering over the actual steel lug nut, which can trap moisture and lead to corrosion and swelling.
The problem occurs when moisture infiltrates the space between the chrome decorative cap and the actual steel lug nut securing the wheel to the vehicle. With road salt and other chemical ice melting agents, this situation worsens. Impact sockets can also damage the lug nuts during tire rotations and other types of vehicle service requiring wheel removal, and using a standard size hex socket on a metric hex nut or vice versa can cause damage to the corners of the thin chrome metal cap, leading to further issues.
The issue of swelling comes from corrosion and moisture getting trapped underneath the cover in between the cover and the metal lug nut itself. Over time, this can lead to rust and more corrosion, causing the lug nuts to swell and making it difficult for the correct socket to fit, which can be problematic when changing a spare tire on the side of the road.
In summary, the swelling of Toyota lug nuts is primarily caused by the corrosion and rust that develops between the chrome decorative cap and the actual steel lug nut, exacerbated by factors such as road salt, chemical ice melting agents, and improper use of impact sockets or hex sockets [[7]].
