I purchased these tires for a custom wheel set. I have hundreds of miles on them and haven't had anything except smooth low-resistance rides. They corner very well. They handle wet like it wasn't and they feel very smooth on the longest of rides. I see others had issues, but I have pounded potholes, swerved into and up curbs and run over water bottles with no problem. Perhaps there are profile issues between rim width and tire width, who knows. These are soft and I expect about 1000-1200 miles will be when I replace them. My experience has been all good.
