What's the best front/rear-'tire pressure' for a long road trip?

Most brands of steel-belted radial passenger tires do not do this, because they use a non-rubberized version of steel for those belts just barely under the tread. These steel belts stretch very very little, so the center doesn't have the flex to balloon out.

We have seen a very very few reports of excess center wear, but without enough detail to track down what really happened.

The old bias-ply tires clearly did balloon out and suffer excess center wear. Any radial tires with belts made of something other than steel, or with inadequate amounts of steel, might also be susceptible to this.

I have had the center wear out before the ends on my 4 runner due to my over-inflating and my daughter has the same problem on her Pathfinder. That’s 2 cases I can personally vouch for.
Interestingly both sets of tires were made by Goodyear.
