One of the tires on our 10 year old car keeps losing air rather fast (2 psi/week). Got it checked from multiple shops but they didn't find any punctures and valve is fine as well. Researched online and found that it might be related to bead leakage because of corrosion inside alloy wheel.
Recommended method is to take off tire, sand/scrub the wheel bead area thoroughly and remount the tire. Is there any decent shop in lahore experienced in this?
