No. A car will get better mileage with the correct tire pressure.

Inaccurate pressure can cause poor mileage, uneven tire wear, or a tire blow-out. To prevent these events from happening it is important to maintain proper tire pressure.
"Ideal" can be subjective. Are you looking for a smoother ride, or longer tire life/better fuel mileage? If a smoother ride is important, go by Subaru's recommended pressure for whatever weight you're carrying in the vehicle. This can normally be found on a decal along the edge of the driver's door. If, like me, you're more concerned about tire life and fuel mileage, run the pressure up to the max that's called out on the tire's sidewall. At this pressure, the tire can safely carry its maximum load, run cooler, last longer, and get better fuel mileage. The main contributor to this is the reduced sidewall flex at the higher pressures. With modern tire construction, you no longer need to worry about poor tread wear like we had back in the bias-ply tire era. The inverse is what got Ford and Firestone in trouble by dropping the tire pressure down to dangerous levels, looking to smooth out the inherently rougher ride on an SUV.
Marginally. Tire pressure has a greater effect! The harder the tire the better the mileage (but the ride is stiffer and the center of the tread wears out faster so it might be uncomfortable and economically a poor idea).
35psi is written on the door sticker of my 94 ex, but I usually run about 40psi all round. Max pressure printed on my tires sidwalls are 44psi. See what works best. Generally, higher pressure gives a firmer ride and slightly better mileage.
Find the maximum pressure on the sidewall of the tire. This depends on your ride preference since you are not using factory recommended tires. The closer to the maximum rated pressure on the sidewall gives you better mileage and less wear to the tire but a harder ride.
When air cools, it becomes denser and actually shrinks. If you check the tire pressure when cold and tire pressure when hot, you'll see that the tire pressure is higher when the tires are warm. Your tires were probably borderline low before the temperature changed. To minimize the effect, you can fill your tires with nitrogen instead. The pressure will fluctuate less. Check the pressure in your tires every time you fill up. You'll get better gas mileage, and your tires will last longer if you maintain the correct pressure in them.
Low tire pressure gives you better traction,especially in sand.Low tire pressure gives you better traction,especially in sand.
It's far better to follow the tire pressure recommended on the tire than on the vehicle.
To reset the tire pressure warning on an E200 Kompressor, use the dash menu settings. Scroll to the mileage menu. Open the Low tire pressure setting. Press the reset option.
It will show the PSI for the tire on the side wall of the tire. Usually it is 32 to 35 for best performance and fuel mileage. Hope this helps.
Yes to a degree. As the pressure is increased, there is less tire contact with the road surface (grip is reduced accordingly) and gas milaege improves slightly.
