Expensive tire sidewall cracks; slow leak

All the tires have needed to be refilled every few weeks anyway - perhaps because they are rated to 42 PSI, but the car maker, Toyota, says to only use 32 PSI on that vehicle.

This is a baffling statement. Why would you expect a tire to leak if the recommended pressure for the car is 32 PSI and the maximum pressure for the tire is 42 PSI?
