The alloys installed were originally sourced from Shershah Scrapyard and then they were lying around with us for around 2 years (atleast) so there were chances of problems after installation.
Our fears came true when one of the tires got flat while the car was parked. After refilling the air, the tire got flat again in less than 5 minutes. So on 6th Sep, I took that rim with tire to Ghareebabad for getting it inspected and repaired.
Luckily the problem was not very big, and was resolved by buffing/ grinding inner edges of the rim.
