Firestone's new model, the Firehawk Wide Oval Indy 500 did a nice job covering up some of the harsh expansion joints and some of the smaller cracks in the road. In my opinion, it let loose just a bit on the off ramp, but all around is a good addition to the category.
The Yokohama S.drive started out with a low drone as that didn't seem to get much better as I drove. However, it did do a nice job of handling the car on the off ramp. It did feel a little rough on the expansion joints, but not too bad.
The BF Goodrich g-Force Sport tire had a growling noise from the start. And it would get louder over different types of pavement. The ride was fairly comfortable, but I could feel the tires give a little when pushed on the off ramp.
That brings us to my winner...the Kumho Ecsta SPT KU31. While there was a little road noise, it was able to fade into the background and didn't become a distraction. This tire was the best over the big expansion joints for ride comfort, and I felt very in control on the off ramp.
We'll see how the tests shake out from the rest of our team, but my vote goes for the Kumho!
