tire companys

[BW from AZ]

Two weeks ago take the wifes car in for two new tires. resist 4 new tire push, move rears to front new on back. life is GOOD.
7 days later both fronts are noticeably low (the old tires). pumpem up to 34 psi and life is OK.
7 more days and they are noticeably low again. go to different store same company they say they cant fix them.
Life starting to suck! too old he says. the car is a 2002 and they were originals but still no where near the wear bars. they showed signs of age with tiny hair line cracks on the side wall and outside tread edge. inside tire, beads even the side wall on the ball joint side looked great. 14 days ago they were good enough to go on the front. what gives?
Did i mention the small nail dead center of the tread, perfectly straight in, just enough to poke the point through tire. i challenge anyone to drop a 5/8 long brad on the road from any height and have it stand up right!!! any trucker knows if its laying in the road the front tires bounce it up and the rear tires pick it up. with luck like this maybe i should play the loto
