what should my tire pressure should be? the size is 205/50/r15

My r15 came from the dealer at 44 psi, i checked w/ a digital gauge. I kept it at 44 for fuel economy. But people have been running pressures from 32-60. On the safe side, just stick to max side wall, and lower to 32 if you want a smooth ride.

A good balance would be about 36 psi. More than 45 is getting into what many consider too firm/harsh which can also prematurely wear on suspension components. Though good things will happen for fuel efficiency. Tire manufacturers/automakers almost always recommends 32 for cars for what is considered a perfect balance of ride, performance, safety, wear, and fuel efficiency. It's up to you to determine your priorities. Just as there're tons of different tires intended for all kinds of individual conditions, tire pressure is variable as well. No one tire does it all, no one pressure does it all. Just don't run lower than 32 or higher than the sidewall indicated max.
