Factory Specs on Tire Pressure?

Seems to me that a 235/60 would need less pressure in the rear than the front, because the usual way to do it would be less pressure in the rear to keep the tire from wearing more in the center from that much pressure with less weight on it.

Going by what the tire says is your best bet though, and just watch for more wear in the center of the tire.
Then if it does wear more in the center of the tire I'd bring the pressure down a little.

Just an oppinion, and how I determin what you asked.
