Default Tire pressure

I am on my 2nd set of tires on my 17x9 rims running 275/40/17 tires. The first set went bald in the center prematurely due to over inflation at only 30psi. these are also wearing out the center. So my question is what pressure should i be running?

I have mine at 32 psi, I would not consider 30 psi over inflating a tire. Are you sure you don't have other problems? Like bad suspension parts.....Are all four tires balding in the center?

The fronts are wearing in the center faster than the rears. But they are a softer compound tire and are due for a rotation. I took my wheels off of my old V6 to put on this car before I sold it. and the tires have done it on both cars. a 25000mile tire wore out in less than 17000 on a V6 that couldnt do a true burn out, the best it could do once they heated up was a quick chirp, and i rarely did that.
The tires that were on the car when I bought it were fine, and they were 17x9 also
Same make and tire design with both sets. I have tried no other tires/makes with these rims.

Thats weird, I run 'high' pressures of ~36-38psi in my tires in a staggered setup that I can't rotate and I'm not getting any excessive center wear.

Its getting irritating. Being in college I cant afford to buy a new set of tires. I need them to last as long as possible. And I dont feel like it is safe to run below 30psi. Hell I dont even like them being that low
