We just had all 4 tires replaced, a week after we got a flat tire. In the past several years not a single flat tire.
The cost of each tire was $55 (with labor I paid $409). The car is a Honda Civic 2007 Hybrid. The tire model says LEAO / LION SPORT GP.
The Mechanics said he put air and he does not find any leaks, he did put the tire in water and no bubbles came out. We have been driving the car for a few days now, and so far there is no sign of any leaks.
I should also mention that I heard some noises right after replacing the tires, and I checked and did not see any issue with them, and only after a week, suddenly a flat tire.
I'm not an expert about cars but my logic mind assumes that the tire was not fully or correctly assembled when replacing the tires. Could that be the cause?
UPDATE - 8 MONTHS LATER
Tires still have no issues. This means it has to be incorrect first assembly, which was fixed on the second assembly.
