I guess I get to be the contrary one, again.
Here are my Roadsmart's after 3,288 miles:
Those are my second set. The first rear developed a puncture at 1,300 miles, so I didn't get to ride it out. That front was changed out at 2,300 miles. It still had some life left, but I was heading out on a 10K-in-2-weeks trip and didn't want to mess with tires so I changed them for ME880's. The ME880's sucked, by the way, but I did get 12,700 miles out of them so they served their purpose.
The Roadsmarts have dual-compound technology like the PR2's, which is the latest in tire technology. However, like the PR2's, the front didn't wear evenly between the harder center section and the softer sides. That gave a noticeable flat spot/cutoff transition that you could feel when falling into corners. I'd thought it was just that I do a lot of freeway miles, but this last set was run 1,000 miles on the twistiest roads in SoCal with minimal freeway time. All that did was wear the sides out well past the wear bars, but I still had that horrible transition into corners. The PR2's gave the same life as other tires I've tried, but the Roadsmarts gave less than half that. And both of those started to go off well before they were worn through. So neither of those was cost effective for me.
I've had the best luck with the Avon Storms. They stick like glue wet or dry and feel good all the way to the end of their life. If I absolutely had to have the mileage I'd go with a Storm front and ME880 Radial rear, otherwise it'll be Storms front and back for me.
