The car maker picks the oem tire for the attributes the want, and calculates the proper pressure from the cars weight so the tire will keep its tread flat on the road. Too high, or low, pressure will cause the tire to wear out the center or edges of the tread prematurely.
Also, it seems Civics for '06, '07, and part of '08, have a control arm problem, that causes vibration and tire wear.
