Giải thích
You should inspect all trailer tires for proper inflation, adequate tread depth, and freedom from cuts, bulges, or uneven wear. Wheels and rims must have no cracks, and lug nuts must be present and tight with no rust streaks indicating looseness. Trailer tires are easy to overlook but critical to safety.
