I believe it's at least the third time in this past year, yesterday (Thursday) when Nadia said the tire got punctured again, this time, on the new back tire, driver's side. I last parked the car in the free parking lot of the train station, close to the Station Bay construction, which is a suspect. The one before this was the back tire on the passenger's side, and we drove it flat for so long that it exploded during examination (pumping) by Costco service guy, a good excuse for him to work overtime just to give us a new tire, gave him like $20 as a tip.
After complaining on South Amboy Facebook, someone advised that not keeping the tires well pumped is also prone to nail punctures.
