Tire pressure

I have always kept my tire spot on at 30psi. They are wearing in the center indicating overinflation. Should I run them with less pressure, 26-28???? Or would that be dangerous. They are Michelin Xone tires, stock rims and tire size.

30 psi sounds low. I would stop by a good tire store and get their opinion.

That's strange. I'm running 32 PSI in Michelin LTX M/Ss on a
1999 2WD Ranger 3.0L FFV, and with 43K miles on them, they
are wearing even.

Hi Hammy211
Are you testing the pressures w/ a hand held tire gage? Maybe you should do several checking w/ 2-3 gauges to see if you end up w/ a constant psi! (this is what you want to know, isn't it!)

Hammy211, one of the very frustrating things nowadays is ... all radials are different ... from one manufacturer to another, and, one DESIGN to another within the same manufacturer. In the old bias ply days, it was ALWAYS the case that over inflation caused increased center wear, and under inflation caused outer extremity wear. However, not always so with radials. Increasing pressure can actually flatten the footprint BETTER, reducing the center wear that you are referring to. But, as stated, you really need to ask someone who knows THOSE tires by heart, and actually DOES know what they're talking about.

My 235/70/16 Good Year's also have worn in the center and have certainly never been overinflated. I too have been wondering how this could possibly occur, I have been unable to come up with any reasonable explanation for it. My original Firestones did not do this. If there are any tire experts out there please clue us in...

BTW 30 PSI is the recomended pressure at least for my front tires..

Just had Goodyear's put on. The Goodyear techs put 34psi all around my 99 Ranger. Original Firestones were kept at 32psi throughout the 64K miles I had on them. Even wear on the Firestones, and they were probably good for another few thousand miles, but I wanted new rubber for this winter.
