While checking wheel rims and lug nuts, which finding suggests a wheel may be loose?
- A.Rust streaks or shiny metal around the lug nuts
- B.A valve stem that points straight out
- C.A hub cap with road dust on it
- D.Tire pressure that matches the sidewall rating
Correct answer
A. Rust streaks or shiny metal around the lug nuts
Why
Rust trails and bright, polished metal around lug nuts are classic signs that the nuts have been moving and the wheel is working loose. The other choices are normal conditions that do not by themselves indicate a fastening problem.
