1. Bead Seal Issue: After tire rotation, the bead may not have seated correctly, causing a slow leak.
2. Valve Stem Damage: The valve stem may have been damaged during the rotation process, leading to a leak.
3. TPMS Sensor Issue: Tires equipped with TPMS sensors can sometimes develop leaks around the sensor if not sealed properly.
4. Punctured Tire: A puncture that wasn't noticed during rotation can also cause a pressure loss.
5. Improper Tire Mounting: If the tire wasn't mounted correctly on the rim, a leak can occur.
Troubleshooting:
1. Check Bead Seal: Examine the tire bead to ensure it's properly seated against the rim.
2. Inspect Valve Stem: Visually check for any damage to the valve stem or any signs of a seal issue.
3. TPMS Sensor Check: Ensure the TPMS sensor is seated correctly and there's no leak.
4. Look for Punctures: Carefully inspect the tire tread and sidewall for any puncture or punctures that may have gone unnoticed.
5. Remount Tire (if Capable): If you're confident in your DIY skills and have access to the necessary tools, you may try remounting the tire to ensure a proper seal. (Note: This is not recommended unless you have experience and proper tools.)
If none of these issues seem to be the cause, it's best to take the car to a trusted tire shop for further evaluation and repair.
