[Aerolla]

I know about the manufacturer's recommendation, and I have ruined at least one set of very nice performance tires on a Mercury Marauder by over inflating them, but those tires had side walls so stiff they were practically run flats. These tires on the Corolla... aren't. They're spongy and soft, and they roll on their sidewalls in sharp turns (which I still do when I'm entering an onramp). In the short period I've owned this car, I've noted wear is greater on the edges than it is in the center, which is yet another motivation to inflate these above the manufacturer's specifications. Tire brand is just as important in determining this as is the label. That is interesting about the Chevy Cruze, but I suspect that the low rolling resistance tires on the Eco also require, or can handle a higher PSI.
