I do 37psi. Figure couple more psi might help mpg but I won't go extreme enough to drastically affect handling. Plus since one tire has a slow leak the few extra psi gives me a day longer before i need to refill .
The placard on the door jamb of my V says 33 psi. That is where I keep the pressure. No abnormal tire wear or handling problems but I guess there shouldn't be if you follow the specifications.
The higher you inflate your tires, the less rolling resistance there will be, which should give you slightly better fuel economy at the expense of a rougher ride, and possible improper handling and tire wear at the middle of the tread if you take it up too far above the recommended inflation pressure.
I go with what is recommended by the factory. Just because the tire manufacter so 44ppsi. Doesnt mean that will be ideal for the car. They research this stuff pretty good has to do with the weight of the car n so on. Im happy with 35 cold, and getting 34 mpg out of it. Gas n tires are not cheap. So I shoot for a good middle ground. :thumb2:
