What causes one tire on my Changan Oshan X7 to repeatedly lose air while others remain stable?

Every few days, one of my tires s by 3–4 PSI while the others are fine. I’ve checked for punctures, but no obvious damage. Could this be a valve leak o r an issue with the rim o r tire bead?

If one tire is losing pressure frequently, it could be due to:

A small, slow puncture nail, thorn, o r sharp debris

A damaged valve stem o r corroded rim edge leading to bead leakage

Improper sealing between the tire and rim due to dirt o r rust

This is common in areas with unpaved o r debris-filled roads. To confirm:

Do a soap water test o r visit a tire shop for a leak test

Have the rim cleaned and resealed

If valve stems are worn, replace them
