Ewww wrong. Tires can and do get flat spots after sitting for a period of time. The tires on my Jeep Gladiator flat spot every night. It takes about 10 miles of running above 45 mph to get them heated up and round again. The tires are 37/12.5-17's. Run 30 psi in the front and 25 psi in the rear. The only time I've seen 45 psi in tires are on truck tires. I run 35 psi on my Z. Tire construction plays a lot in if a tire flat spots or not too. I've had other brands of tires flat spot too.
