I have Michelin LTX MS/2s on my '06 Ranger and they've been excellent. I used to have the OEM Goodyear Wrangler RT/S and they were fine in dry weather, absolutely horrible in the rain and snow. I also have the 5-spoke wheels and mine are also corroding around the centers like yours.
I also have Michelin Defender LTXs on my Sienna and they're great tires as well.
