I have em' and I hate em' I really liked the Avon Tech M500 I had before, stuck like glue, but wore out in 6k miles. The SPT grips good as long as the road suface is consistant and smooth, as soon as there is a road suface variation the SPT hunts for grip and does not respond quickly leaving you with a floating feeling until it decides to grip the road again. I purchased the SPT based on Tire Racks tests and I now I wish I had just bought the Avons again and dealt with crappy tire life.
